How Long Can Bed Bugs Live Without Eating
How Long Can Bed Bugs Live Without Food?
Science can be frustrating. You may have been researching “how long bed bugs can survive without food” for a while now and found 63 different answers. Why are there 63 different answers? Why can’t you just get one answer and be done with this? You may read on a website that they can survive 18 months or more without food and how on Earth is that possible? Let me clarify and provide you the answer you’ve been looking for…..sort of….
The reason there are 63 different answers is because different factors and influences can change how long bed bugs can survive without food. Let’s take age for example. We know that 1st instar or “baby” bed bugs (right after they hatch out of an egg) can’t survive without food as long as adult bed bugs. Seems fairly simple and straightforward as a newborn human couldn’t survive as long as an adult without food. Activity level can also change the time it takes for bed bugs to die in the absence of food. If a bed bug is in a vacant apartment actively searching for food, they can’t survive as long as a bed bug in a jar on a scientist’s desk. As the bug in the vacant apartment wanders around looking for food, it is using energy and, therefore, will succumb sooner than the bug sitting in the jar. Again, using humans as an analogy, if someone is starving in a desert and wandering around looking for food they will succumb to the conditions sooner than if someone is stuck in a cave and can’t move around and use energy as quick as the person wandering. Make sense why there seem to be 63 different answers?
So the answer to the question depends upon why you are asking? If you have a vacant apartment that has bed bugs, and you want to know when it can be rented out, the answer is probably nine months or more. Research has found live bed bugs in vacant apartments six months after they vacated and how long they survive depends upon how active they are, the temperature in the apartment and what stresses they may have been exposed to. Because of all of these factors, there is no way to guarantee how long you should leave an apartment vacant to starve the bed bugs inside. In fact, you may be putting surrounding apartments at a higher risk as the bugs in the infested, vacant apartment are probably going to search for food, and that may increase the chance that a surrounding apartment becomes infested.
In a similar scenario, I have found live bed bugs in summer camps ten months after they were vacated. The difference in this setting is that the cabins were not heated over the winter, and the cold temperatures assisted the bed bugs in surviving longer than normal. How long could they have survived? The world may never know….
Lastly, many ask this question because they have personal belongings they want to seal in bags or in storage and want to know how long they have to leave the items before they can use them again. Unfortunately, this may be the toughest question to answer. You can find reports online that state people have observed bed bugs surviving 18 months or more when placed inside a jar and left in storage. To be honest, 18 months seems a bit long to me but bugs inside a container or bag and unable to search for food could probably survive 9-12 months or maybe much more. A good recommendation for this scenario is to add stresses to the setting to make the situation as difficult as possible on the bugs. Increasing the temperature, adding pesticidal dusts when possible (by label directions) and other treatment options can increase the stress on bed bugs in these situations and decrease the time they can survive.
So the answer to the question is…….don’t rely on starving bed bugs as a treatment option. Too many factors can influence how long they can survive and unless you can survive without an item for 12-18 months or more I would recommend finding a way a way to treat the item.

Bed bugs are blood-sucking insects in the family Cimicidae. Both nymphs and adults feed on sleeping or sedentary humans, mostly at night, a time when this pest’s stealthy habits are difficult to observe.
Bed bugs are found worldwide in association with human habitations. The common bed bug,Cimex lectularius, is a widely distributed species most frequently found in the northern temperate climates of North America, Europe, and Central Asia. It occurs more sporadically in southern temperate regions. In tropical regionsC. hemipterus, the tropical bed bug, is the dominant species. The most common species found in California isC. lectularius.
The growth and development ofC. lectulariusis optimal when it feeds on humans; however, this insect also feeds on other species of mammals and on birds found near the home including chickens, mice, rats, and rabbits. Bat bugs and swallow bugs, close relatives of bed bugs, may also be found in and around human dwellings and may sometimes bite humans, although their preferred hosts are bats and birds, respectively.
Until recently, bed bug infestations were thought to be associated primarily with crowded and dilapidated housing. However, bed bugs have undergone a resurgence in pest status and can now be found even in the finest hotel and living accommodations. The reasons for this resurgence aren’t totally understood but appear to involve increased global travel and commerce, ease of movement of infested items, widespread insecticide resistance, and changes in pesticides available to control this pest.
IDENTIFICATION AND LIFE CYCLE
Adult bed bugs are oval, wingless, about 1/5 inch long, and rusty red or mahogany. Their bodies are flattened, they have well-developed antennae, their compound eyes are small, and the area behind the head (the pronotum) expands forward on either side of the head, bearing many small hairs. The immatures, called nymphs, appear identical to the adults except for their smaller size (1/20 –1/5 inch), thinner outer skeleton (cuticle), and lighter yellowish-white color.
Bed bugs are readily distinguished from another common blood-sucking species, conenose bugs (also known as kissing bugs), by their smaller size, more rounded shape, and lack of wings as adults. Conenose bugs may be up to 3/4 inch long. (SeePest Notes: Conenose Bugs.)
Bed bugs can be distinguished from their close relatives bat bugs and swallow bugs by comparing the length of the hairs on the pronotum to the diameter of the eye; this requires a hand lens or microscope. These hairs are shorter than the diameter of the eye on a bed bug and longer than the diameter of the eye on bat bugs and swallow bugs. This distinction is sometimes important to make, since managing these bed bug relatives involves managing their vertebrate hosts (i.e., bats and swallows) nesting in, on, or near homes.
Female bed bugs lay 200 to 500 tiny (1/20 inch) white eggs during their lifetimes, usually two to five eggs per day, on rough surfaces such as wood or paper near their hosts’ sleeping places, resting places, or both. Gluelike material covers the eggs, which hatch in about 10 to 15 days at room temperature. After hatching occurs, the eggshells frequently remain stuck in place.
There are five progressively larger nymphal stages, each requiring at least one blood meal before molting to the next stage. The entire life cycle from egg to adult requires anywhere from five weeks to four months, depending on temperature and availability of food (blood). Development occurs most rapidly when temperatures are between 70° and 82°F.
Both nymphs and adults generally feed at night and hide in dark cracks and crevices during the day, although hungry bugs may feed any time hosts are nearby and sedentary. Common hiding places are typically located within 6 or fewer feet from areas where humans sleep or rest and include: along mattress seams and tufts; beneath covers; in wood joints of box springs; in cracks and joints of bed frames; behind baseboards and headboards; under loose wallpaper; behind picture frames; and inside furniture, appliances, electronics and upholstery. Bed bugs are more likely to harbor in or on materials made of wood, paper, or fabric as compared to those made of metal or plastic.
Occasionally, people may pick up bed bugs in theaters or on buses and trains. People can also bring bed bugs into their home on infested clothing, bedding, furniture, and luggage.
Bed bugs can go without feeding for 20 to 400 days, depending on temperature and humidity. Older stages of nymphs can survive longer without feeding than younger ones, and adults have survived without food for more than 400 days in the laboratory at low temperatures. Adults may live up to one year or more, and there can be up to four successive generations per year.
Bed bugs feed on humans, usually at night when they are resting. This insect feeds by piercing the skin with its elongated mouthpart, which consists of four stylets that normally fold under its body when at rest but fully extend during blood feeding. Two maxillary stylets form canals, a small salivary canal that carries saliva into the wound and a relatively large food canal through which body fluids from the host are taken in.
A bed bug can take up to six times its weight in blood during one feeding event, which takes between 3 and 10 minutes. Usually people aren’t aware they have been bitten until afterward; bites occur while people sleep, and bed bugs are known to inject a natural anesthetic while feeding. However, saliva injected during the feeding can later produce allergic dermal reactions such as large itchy swellings on the skin. These may become irritated and infected when scratched. Swelling may not develop until a day or more after feeding, and some people show no symptoms at all. Bed bugs have never been shown to transmit human disease.
Distinguishing bed bug bites from the bites of other arthropods such as mosquitoes, fleas, and spiders is difficult to impossible. People often confuse itching bed bug welts with mosquito bites. The only way you can really confirm bed bugs as the cause is to find the bugs or their signs in your bed or bedroom. Often people are bitten when traveling and may be unable to produce a specimen, making diagnosis even more difficult.
In addition to direct injury to humans, bed bugs leave odors and unsightly fecal spots on bed sheets and around the insects’ hiding places. These spots are usually reddish brown or dark brown to black, sometimes yellowish, roughly round (although sometimes they appear as streaks), and can be very small.
How to inspect for bed bugs(2:20)
Confirmed bed bug infestations should be managed by trained professionals. Managing a bed bug infestation is a difficult task that requires removing or treating all infested material and follow-up monitoring to ensure the infestation has been eliminated. Management will require employing several nonchemical methods such as vacuuming, washing bedding at a high temperature, using steam or heat treatment, and sealing up hiding places.
Insecticides may be required to eliminate serious infestations. Several active ingredients are federally registered for bed bugs for over-the-counter use, but few have been demonstrated as effective. Pest management professionals (PMPs) have access to a wide range of effective registered products; however, insecticide resistance among bed bug populations is increasingly common. The best approach is to combine chemical and nonchemical tactics with increased sanitation and habitat modification practices. Prevention and monitoring of bed bug infestations are paramount and should be ongoing.
Monitoring and Detection
The presence of raised wheals, blisters, rashes, or any other dermal symptom associated with arthropod bites should never be used for diagnosis, since several household pests are known to bite humans, and since reactions vary widely between individuals. You can confirm a bed bug infestation only by detecting the pests themselves or their signs, which include fecal spots, blood spots, egg cases, and shed skins (exuviae).
Current research indicates 85% of bed bugs are found in or near the bed, so inspections for infestations should initially focus on the mattress, box spring, bed frame, and headboard. Lift the mattress and inspect all its seams and surfaces as well as those of the box spring. You may need to dismantle the bed. Keeping in mind bed bugs can utilize cracks and crevices as small as the width of a credit card, make sure to thoroughly inspect all potential harborage sites. Use a flashlight and a small mirror to aid in the inspection process. It can take a good deal of time, patience, and perseverance to detect low-level infestations.
Remember, these nocturnal insects are small. Although you can see adults and aggregations of nymphs with the unaided eye, seeing the eggs requires a hand-magnifying lens. Make sure to look for dark spots of dried bed bug excrement, blood spots where engorged bugs were inadvertently crushed, or the insects’ light-colored shed skins. A foul, rotting, bloody meat, or acrid “buggy” smell might be present in heavily infested areas.
The remaining 15% of infestations usually are in upholstered furniture other than beds; in bedroom cabinets; along baseboards; under wallpaper; and in carpets, wall hangings, and similar hiding spots. Bed bugs prefer fabric or wood surfaces to metal or plastic. When there are heavy infestations, keep in mind that adjoining rooms, filing areas, and clutter can be out-of-the-way shelters.
Recent research has shown that canine detection utilizing dogs conditioned to the scent of bed bugs can be an effective tool for detecting bed bug infestations. Laboratory and simulated field studies have shown this method can be very accurate; under actual field conditions, however, canine detection accuracy has been highly variable. Therefore, third-party certification and ongoing training of any canine team should be verified before hire, and any canine detection alert should be confirmed with a detailed inspection by a trained PMP.
Other recent research indicates monitors that attract or intercept bed bugs moving between a hiding place and a host can aid in bed bug detection, particularly when using several monitors near beds or suspect locations. Pest management professionals are already widely using these monitors. Although quite diverse in terms of size, appearance, and price, monitors generally fall within one of two categories: active monitors or passive monitors. All monitors have the benefit of ease of inspection as compared to potentially having to disassemble furniture and other household items to find bed bugs.
Active monitors employ an attractant—usually heat, carbon dioxide, host odors (kairomones), pheromones, or a combination of these—to lure bed bugs out of their harborage areas and into a pitfall or sticky trap within the monitor. These devices have the potential, especially in the absence of a host, to detect bed bugs that would normally remain hidden. Airborne aggregation pheromones and other behavior-modifying chemicals might someday help detect low-density infestations.
Passive monitors either exploit a bed bug’s affinity for dark crevices or rely on chance encounters with pitfalls or sticky traps.
Interceptor monitors are a hybrid between active and passive (pitfall) monitors in that they rely on the presence of a host (a sleeping human) to attract hungry bugs and then trap the parasites on route to their meal. These small double-cupped monitors are easily installed under the legs of beds and other furniture items. Research has demonstrated that such interceptors trapped six times more bed bugs than were found from human visual searches alone.
People may bring bed bugs into their homes in luggage or on clothes after visiting an infested dwelling or hotel. If you travel frequently, look for signs of bed bugs in your hotel room by checking behind headboards and under sheets and by inspecting mattress seams and tufts, especially if you have been bitten. If you suspect bed bugs are present, change rooms or hotels. Inspect your luggage before leaving, and as soon as you get home, wash and dry all your clothes at the hottest settings the fabric will permit. Frequent travelers may want to store luggage away from the bedroom, such as in the garage or a hall closet.
You may also inadvertently bring bed bugs into your home on infested bedding or furniture. If you purchase second-hand furniture, especially beds or mattresses, thoroughly inspect the item before bringing it into your home. If you remove infested mattresses or furniture from your home, don’t leave them on the curb or porch. Take such items immediately to the dump or clearly mark them as infested by bed bugs so others won’t unknowingly bring the items into their homes.
Managers of hotels, furnished apartments, dormitories, homeless shelters, and other facilities that house transient populations need to train staff to recognize signs of bed bug activity and take action as soon as they find an infestation. One proactive step a manager can take is to regularly replace beds, mattress, and bedding materials. Frequently laundering bedding and placing potentially infested items into walk-in freezers or heat units during tenant turnover can help prevent the spread and establishment of bed bugs. Keep clutter down, so it is easier to inspect and so bed bugs have fewer hiding places. Also, seal up cracks, crevices, and holes in bedding, furniture, and other potential hiding sites. It is much easier to manage a bed bug infestation when the population is small.
A number of nonchemical control methods can be used to manage bed bugs. These methods are directed at killing or removing bugs or restricting their access to beds or bedding material.
You can remove bed bugs and eggs with the suction wand of a strong vacuum; however, you must target the seams of mattresses and box springs, along perimeters of carpets, under baseboards, and in other areas where bed bugs live. A single vacuuming rarely gets all bugs and eggs and should, therefore, be repeated. Portable steam cleaners and other steam delivery devices can kill all bed bug life stages, so these items can also be used to clean mattresses and furniture. Care must be taken, however, to ensure steam penetrates into the areas harboring bed bugs and their eggs.
Commercial heating services are available to treat entire rooms in homes for bed bug infestations. The current recommendation for effective commercial heating services calls for a temperature of at least 140°F for two hours or 130°F for three hours (the minimum lethal temperature is 113°F), which will kill most bed bugs and eggs. In California, providers of heat services must be licensed and bonded by the Structural Pest Control Board. Chilling to a temperature of 32°F or lower and maintaining this temperature for several days will also kill bed bugs.
For suspected infestations in clothing or bedding, a home laundry drier at the hottest setting can be effectively used to deliver the necessary heat. At least 10 to 15 minutes exposure will be needed. Before using this method, consider whether heat will damage the fabric.
Mattress encasements specifically designed to prevent bed bugs from establishing harborages on mattresses are commercially available and have been shown to be effective through laboratory research. Encasements are particularly useful for hotels or other facilities with many beds. Encasements can also be used to contain bed bugs within mattresses when they can’t be discarded or when control tactics such as steam or insecticide application are unavailable or undesirable. Bugs trapped inside encasements will eventually die due to starvation.
Other management practices include sealing up hiding places where bed bugs can hide such as cracks and crevices in walls and around windows and doors. As a temporary measure, you can sometimes exclude bed bugs by using commercially available double-cupped monitors that are easily installed under bed legs.
Insecticide applications alone won’t control bed bug infestations. Insecticides must be combined with infestation prevention measures—a program of removing and cleaning infested beds, bedding, and other harborage sites—as well as nonchemical tactics such as steam or heat delivery and an ongoing evaluation and detection program to ensure treatment was effective and to manage future infestations early on.
The most effective bed bug pesticides are available to commercial pesticide applicators only. Professionals also have the equipment and expertise that allow for a more effective and precise application of insecticides. In addition, professionals have the training to detect and isolate infestations, which often allows for more effective long-term management.
Insecticides may be applied as liquids directly to cracks, crevices, bed frames, baseboards, and other similar sites, or they may be applied as dusts in cracks and crevices. Pesticides aren’t generally applied to mattresses or bedding because of potential risk to people. Using over-the-counter total-release aerosol foggers has been shown to be ineffective for bed bug control and potentially harmful to residents; therefore, they aren’t recommended.
Liquid insecticide formulations, many of which are available for use only by PMPs, include:
- Products containing the botanical insecticide pyrethrin, which gives quick knockdown but little long-term control
- Various synthetic pyrethroid products (e.g., cyhalothrin, bifenthrin, deltamethrin, and permethrin)
- Mixtures of pyrethroids and neonicotinoids (e.g., Temprid and Transport)
- Various botanical oils
- Newer types of products including the pyrrole insecticide chlorfenapyr (Phantom) and the insect growth regulator (IGR) hydroprene (Gentrol)
Fumigation using the active ingredient sulfuryl fluoride is commercially available for bed bug control in California and can be highly effective. However, this is a highly specialized and regulated treatment method, best for remedial control only. Since fumigants have no residual effects, other methods or a combination of methods will be needed to prevent reinfestations.
Some bed bug populations have developed resistance to pyrethroid insecticides and no longer can be effectively controlled by them. Therefore, there is growing interest in alternatives such as the mixtures, botanicals, and IGR listed above. Some studies, however, suggest that mixtures containing pyrethroids continue to drive resistance, that oils have little to no residual action, and that chlorfenapyr and hydroprene may take many days to kill bed bugs.
Insecticides applied as dusts cling to the pest’s cuticle, wearing away the insect’s protective wax covering or poisoning the insect when it grooms itself. Several dust products used in bed bug management include borates, diatomaceous earth, silica gel, and formulations containing pyrethrin or pyrethroids. These materials can provide long-term control as part of an integrated program if they are placed in out-of-the-way places, such as under baseboards or in wall voids, that don’t get wet. Bed bugs may not groom themselves to the same degree as other pests, such as cockroaches, so insecticide dusts requiring consumption, including borates, may be less effective than anticipated.
Although over-the-counter pesticide products that have bed bug control written on the label can be found on store shelves, they aren’t generally recommended. Performance of these products under actual field conditions isn’t known. If you need to use a pesticide, you are better off hiring a licensed professional pesticide applicator with experience in treating bed bugs; seePest Notes: Hiring A Pest Control Company.
Residents do have an important role to play when their homes are infested with bed bugs. Once professional treatment has occurred, you should continue to monitor for bed bugs daily. Also, keep down clutter, and vacuum previously infested areas regularly.

HOW LONG CAN BED BUGS LIVE WITHOUT FEEDING?
How long can bed bugs live without blood? The answer depends on the age of the bed bug, if it is resistant to certain pesticides and the temperature range it is exposed to. “How long can bed bugs live without feeding before becoming adults?” is the first question to ask yourself.
A newly hatched bed bug is called a nymph. Nymphs go through five stages before becoming mature adults. When a bug molts, it sheds its skin. Immature bed bugs molt five times before reaching maturity and must feed in between every molt. For that reason, nymphs must feed more often. Despite their young age, newly hatched bed bugs can still survive for at least a few weeks without feeding.
But if nymphs can survive weeks without feeding, how long can bed bugs live without blood after maturity? That depends. When living in warm conditions, bed bugs will usually try to feed at regular intervals. Adult bed bugs can survive for about five months without a blood meal.
Once the bed bug settles on a host, it will feed for a few minutes. Length of feeding depends on the stage of development, how much it ate last time and how long it’s been since it last fed. After the bed bug is full, it will leave the host and return to a crack or crevice, typically where other bed bugs are gathered.
Bed bugs usually feed every three to seven days, which means that most of the population is in the digesting state, and not feeding much of the time. However, because bed bug infestations can spread so rapidly, it can often feel like you are waking up with new bites every morning. This can lead to high stress levels and a lack of sleep.
Don’t let bed bugs get the best of you. A pest control specialist can help you kick bed bugs out of your house and keep them out.

How long can bed bugs live without eating?
How long can bed bugs live without eating?
Lab testing says 20-400 days. Other sources say anywhere from 2 weeks to 2 years, depends on where you get the information. The one concrete piece you get across the board is temperature. Basically the colder it is, the longer they live, because their body goes into a state of hibernation to conserve energy as it is too cold for them. Not only that but with warmer temperatures they’re more inclined to feed, as they are attracted by body heat, because they use heat to seek out food sources.
In normal room temperature and humidity conditions, up to 6 months, often longer, especially when colder. In high temperatures their metabolism is faster and they will feed more often, which can also shorten their life drastically with no food, anywhere from 2 weeks from 2 months depending on lifestage and exact conditions. Bedbugs are quite hardy, and waiting them out of a house requires high temperatures and a lot of time.
Do you use fabric softener on your bedding? I have found I am allergic to it and wake up with red itchy spots all over if i sleep on bedding if fabric softener was used on it.
Same shit with dryer sheets.
I’m guessing your roommates do not react to bed bug bites, like a healthy swath of the population.
How Long Can Bed Bugs Live Without Food?
If you’re hoping that staying with friends for a week will take care of your bed bug situation at home by starving the little pests out, you may want to come up with a new extermination plan. Let’s look at how long bed bugs can live without food, so you’ll know what you’re dealing with.
You’ve probably never wanted to be an expert on bed bugs, but if you’re the one facing an infestation, you may want to get to know your enemy better. By the end of this article, you’ll know everything there is to know about a bed bug’s life span and feeding habits.
How Long Do Bed Bugs Live On Average?
Bed bugs are no slouches when it comes to longevity. While you might not think a bug will live very long, bed bugs have a lifespan of a year to 18 months.
That is part of the reason infestations can spiral out of control so quickly. Bed bugs live a relatively long time and they can produce a lot of offspring during that time. The average lady bed bug can produce anywhere from one to seven eggs every day after she has had a meal.
During her lifespan, a female bed bug can lay up to 250 eggs if she is feeding regularly on a human’s blood. Because of all the children they produce who will in turn reproduce, one single female bed bug can lead to a bed bug infestation of over 5,000 bed bugs just in a six-month time frame.
That’s why it’s essential to take any bed bug sighting seriously because, in no time flat, you could have a full-on invasion happening.
Bed bugs have several stages throughout their lives. But under perfect conditions, they go from being an egg to a nymph to an adult in 37 days or so. Nymphs, which are baby bed bugs, shed their skins five times before becoming an adult.
The warmer the weather is, the faster the bed bug will reach maturity.
How Often Do Bed Bugs Usually Feed?
When they can, bed bugs like to be regular feeders. If a food source is available, they like to eat one time every week. And if they’re living in a house, that usually isn’t a problem because their food source will be living there with them. But if you’re on a two-week vacation and your pets are with you, the bed bugs in your house won’t be able to feed as often as they want to.
To get out of the nymph phase, bed bugs must feed. For every time a nymph sheds its skin on its way to adulthood, they need to feed on blood. Without a meal, they won’t shed their skins and reach adulthood.
Although they prefer regular meals, sometimes conditions don’t allow for that to happen.
How Long Can Bed Bugs Live Without Feeding?
While bed bugs like their food sources to hang around so they can have unlimited blood meals after dark, they can likely go much longer than you think they can without a meal. Many organisms would die long before a bed bug if they stopped feeding, but a bed bug’s greatest trick might be surviving a long time without a host (so tightly wrapping your infested bedding up in a plastic bag for a few of weeks isn’t going to work, unfortunately).
The colder it is, the longer a bed bug can go without feeding, due to its reduced activity level.
In colder weather, bed bugs can get away with feeding much less than their preferred once a week. If the temperature drops below 60 degrees Fahrenheit, bed bugs aren’t as active as they are in warmer temperatures, meaning their energy requirements aren’t as high. This also means they’re rather good at surviving outside as well as indoors, even in the cooler months.
In that case, bed bugs can live for several months without feeding on blood as adults. Nymphs, although they won’t grow without feeding, can make it to around three months without a meal.
In the winter, bed bugs can go even longer without feeding. In low humidity conditions and temperatures of 44 degrees Fahrenheit, bed bugs have survived an astounding 560 days with a meal in a laboratory setting.
That means, in cooler conditions, you won’t be able to stay out of your house long enough to kill off those bed bugs by means of starvation. Since they can go so long without having to have blood, you won’t be able to stay away from your house long enough to kill those bugs.
They’ll just slow down their activity level until you’re back in the house and they can feed on you. If you live in an apartment building, they might try to check out your nearest neighbor if they get desperate and there’s no one in your unit for a couple of weeks. But that’s not a good extermination plan – you don’t want to stick your neighbors with your bed bug problem.
Will Bed Bugs Feed On Other Animals If Desperate?
It’s always nice to be wanted – until the one who wants you is a bed bug. But even though we wish we weren’t, the fact is that humans are a bed bug’s preferred food source. They are attracted to the carbon dioxide and warmth you put off.
As we exhale, we put off carbon dioxide. Since we’re fairly big creatures, especially to a bed bug, we put off a lot of it. This is one of the primary reasons bed bugs are drawn to us – because of our carbon dioxide output.
But since bed bugs also thrive in warmer conditions and enjoy heat, they’re drawn to us for that reason as well. That’s especially true while we’re all bundled up in our blankets in our bed. And if there are two people in the bed, that’s even better for bed bugs because the shared body heat will make things even hotter. And that’s irresistible to a bed bug.
Although we’re their favorite snack, bed bugs will hunt out whatever food source is available if times get tough. That includes animals that live in your household like cats, birds, and dogs.
But before you start wringing your hands being worried about your pet’s health, keep in mind that they’re a lot of trouble for bed bugs to feed upon. They have a lot of fur and hair that a bed bug has to work their way through before they are able to get to the skin. They’d rather bypass the pets and go straight for us.
They aren’t as well equipped as other types of pests, like fleas, to deal with your pet’s fur.
If you’re worried because you’ve seen bed bugs on your pet, you can take the cat or dog bed you keep in your house and toss it in your dryer for 30 minutes. Make sure the dryer is on a high heat setting. You can wash the bedding first if you want, particularly if you haven’t washed it for a while. But the heat from the dryer is what’s going to kill the bed bugs, not the water from the washer.
After you’ve washed the bedding, you should make sure you don’t put it back in your bedroom until your bed bug problem is taken care of by an exterminator.
You should also keep it away from any couches or chairs because although bed bugs like to stay within several feet of your bed, they have been known to spread out to hide in the crevices of couches and chairs in living rooms. And if your pet’s bed is nearby, they’ll continue to be a bed bug target – although not as desirable of a one as you are.
Can Bed Bugs Reproduce Without A Meal?
Bed bugs need blood for just about everything they do. They need it to grow. And they need it for reproduction purposes as well.
Before bed bugs can become adults capable of reproducing, they must first have several blood meals. If they don’t eat, they won’t become adults. They’ll stay in the nymph stage until they have five meals.
After they become an adult, the female bed bugs must eat if they want to lay eggs. If you cut off a bed bug’s food supply, they won’t be able to reproduce. This a good method of preventing bed bugs, but is unlikely to work if the infestation is very large.
But again, since bed bugs don’t have to eat regularly, it’s really hard to find a way to cut off their food source.
How To Get Rid Of Bed Bugs With DIY Treatment Methods
Hiring pest control professionals can be costly, and while it’s usually the best option, there are some preliminary steps you can take to get rid of bed bugs yourself.
1. Carefully bag and wash all of your bedding and clear any clutter around the room. Bed bugs love to hide in piles of clothes, so remove these and wash them before you start cleaning.
3. Use a high-powered vacuum to clean around the bed to take care of stray bugs and eggs. Using a vacuum with a HEPA filter is vital to ensure bed bugs cannot escape once captured. The Shark Navigator Upright Vacuum easily ticks all of the boxes while remaining lightweight and easily maneuverable.
4. Use a specialist, non-toxic bed bug spray to clean your bed-frame, headboard, and surrounding furniture. Bed Bug Patrol Bed Bug Killer is a completely natural spray that has a reported 100% kill rate against live bed bugs in controlled tests, and most importantly, it’s child and pet-friendly.
5. Pull your bed away from the walls and place bed bug interceptor cups under each leg. These will isolate your bed and help to prevent the spread of bed bugs. Additionally, interceptors can serve as tools to help you track progress. Ideally, the interceptors should contain fewer bed bugs every time you empty them. My favorites are these Bed Bug Blocker Interceptor Traps.
6. Using a bed bug mattress protector to encase your mattress will either help to save it if it’s yet to be infested, or otherwise keep bed bugs trapped in and around it until they eventually die of starvation. My favorite is the SureGuard Mattress Encasement which is thick, strong, and will help to stop bed bugs of all sizes from getting to, or from, your mattress. A SureGuard Box Spring Encasement is also available.
7. If you wish to be extremely thorough, specialist bed bug heaters can be purchased to raise household items to a temperature that is sure to kill all bed bugs and eggs. ZappBug is the most popular option, and is designed to automatically reach the all-important killing temperature to eradicate all stages of the bed bugs life cycle. Large and small versions are also available.
So now that you know how long bed bugs can live without food, you’ll have a better idea of just how tough and resilient these little pests are. They can survive a lot of harsh conditions, including starvation and cold temperatures. When you factor that with their speed and great hiding skills, it’s no wonder bed bugs can be so hard to eradicate.
If you find yourself with a bed bug problem, before you decide to handle it on your own terms, you should call in the experts. They’re used to dealing with bed bugs and they know just how difficult they can be to fully knock out. And now you know that trying to knock out a bed bug’s food supply won’t work, so you’ll likely gladly cough up the money needed to get rid of them once and for all.
