How Bed Bugs Die

Will Bed Bugs Die if They have Nothing to Feed On?

In the case of many insects, homeowners get rid of them by simply taking away their food source. If someone has an ant problem, they’ll clean the surfaces in their kitchen and ensure there was no food lying around. They are a living creature and so, they cannot live without a food source. It makes sense then, that bed bugs would work the same way, right? The answer to that question is not as cut and dry as you may think. For example, going down and checking into a hotel for a few days isn’t going to solve the problem. While bed bugs do need a food source to survive, they can go quite a long time without one.

How long a bed bug can live without food depends on several factors. These include the age of the bug, if it is resistant to any pesticides, and the temperature of its environment. It also depends on the maturity of the bed bug.

Newly hatched bed bugs are called nymphs. These baby bed bugs go through five different stages before they are considered mature bed bugs. During each nymph phase, the bed bug molts and it must feed with each molt. Due to this, nymphs must feed more often than adult bed bugs. Even with this more frequent feeding, nymphs can still live for several weeks without a food source nearby.

Fully mature bed bugs typically feed every three to seven days. When they are living in a warm environment, they will feed quite regularly. When a bed bug wants to eat, it will leave its crevice and find the host. The length of feeding time will depend on several factors such as how much the bug ate at their last feed, how long since it has fed, and the developmental stage it is in.

Adult bed bugs can go five months or more without a meal. Even though they don’t feed as often as nymphs, and most of the colony is in a digestive phase, bed bug bites are still a real nuisance.

How long does it take for bed bugs to die without human contact

Scientific studies have shown that bed bugs (cimex lectularius) adults can live as long as 400+ days without feeding in a laboratory at low temperatures.

Adult bed bugs can live for more than a year and it was found that there can be up to four successive generations per year. As for nymphs the life span is shorter than adults.

  • Adult bed bugs can live 14 months without feeding
  • Nymphs live 5 months without blood meal
  • Females need first blood meal to lay eggs

Starving a bed bug is not an effective strategy in removing an infestation.

Pest management professionals follow specific guidelines to get rid of bed bugs permanently . These procedures will help identify the necessary effort to quickly remove a bed bug infestation in any size property.

To help reduce outbreaks please share with friends and family.

Do bed bugs die if they do not feed?

Bed bugs do require to feed (blood meal) in order to survive, yet there is a 14 month life span of a adult bed bugs without human contact found in scientific studies.

The complete life cycle of a bed bug requires at least one blood meal before molting to the next stage, this again depends on temperature and availability of food/blood meal.

Keep in mind development occurs more rapidly at temperatures between 70° and 82°F.

Can bed bugs live in a vacant house?

Due to an adult bed bug life cycle can last 400+ days without a host. It’s very common bed bugs can live in a vacant home.

Due to the feeding cycle of bed bugs, they may migrate to where a blood meal can be found. This may be the cause of an infestation from a neighbors home that is in your living vicinity.

What is the average lifespan of bed bugs?

The life stages of a bed bug are based on five nymphal stages (not including the egg). Each stage requiring a blood meal before molting to the next stage.

  • Egg – Eggs are white and oval shaped (about 1/16 long)
  • Tiny white nymph – Difficult to see (about 1.5mm) Look like specs of dirt until they move
  • Light nymph with black spot – (about 2mm) Noticeable black spot in abdomen area
  • Light brown nymph – Lager in Size (about 2.5mm) Resembles an apple seed in shape
  • Medium brown nymph – Size increases (about 3mm) smaller version of the adult bed bug
  • Darker brown nymph – Larger in size (about 4.0mm) More pronounce black spot on abdomen
  • Adult – Reddish brown “rust color” flat oval shaped body (about 4.5mm)Egg

How long can a bed bug live with a host

Can bed bugs or eggs travel on the botshoesr to of your shoes

Yes they can, it is very common they travel from suitcases into your home. Another way we have a lot of readers get them is from their kids backpacks in school. They then come home with the bed bug in the back pack and that night, they begin burrowing into the beds and start feasting. A week later you begin to start noticing the bites.

So its very common these bed bugs migrate on shoes, luggage, clothing, etc.

I had a K 9 detect bed bugs in 1 room in my apartment. I had to pack up the entire apartment in plastic bags in the middle of the flood. I had 3 treatments. The last treatment was in November. there has been no known activity since. We can I finish unpacking and know that the treatments were successful

AWESOME. to hear your bed bug issue is gone. If your not feeling bites for a two week period or so, you can assume a success.

Although… please be aware, neighbors, public transportation, kids backpacks… other external things outside your home. This can bring back bed bugs. It’s possible… not always likely but it happens.

So its always recommended, while you do a monthly cleaning, simply SPOT-Treat your beds, couches, and walls, clothing areas with GreenBeanBuddy residual bed bug spray. This will prevent the pests from migrating from any outside sources.

Thankyou for sharing your story, we’re so thrilled you got rid of your bed bugs! We love it when customers tell us this.

Nobody seems to address specifically: Can bedbug EGGS lie dormant to hatch at a later time, when conditions are more favorable? How long can they last? Will adding moisture to dry old bedbug eggs reactivate them?

Hi Tom, thanks for reaching out. I will be happy to answer your questions. We have bed bug specialist on staff that confirm the answers as well.

As for EGGS being dormant and hatching, yes nymphs(hatchling bed bugs) do lay dormant then hatch later. This is why we recommend a re-treatment around the 7 day point, because this 2nd treatment cycle will get the nymphs that look to feed. These are usually very tiny ones you cannot see very well, yet you feel the bites. (And their bites are usually the more painful ones because they do not inject you with the numbing agent that the large bed bugs do when feeding.).

EGGS cycle usually hatch every 7 to 14 days.

Adding moisture to dry eggs will not re-activate them. In fact, Green Bean Buddy is so effective because the formulation kills bed bugs using a dehydration method that seals out the bed bugs moisture from the inside out, thus causing them to die without becoming immune to our formulation. So the nymphs are affected in the same way.

Thanks for contributing, your questions will help the community and assist us in which guides we should add to help more of bed bug victims and our clients.

Let me know if you have any more questions.

I noticed there are bed bugs in my house and I used pesticides on them, though most of them died but I realized their eggs were still there, my question is, can the pesticide kiilbthe eggs? If it can’t how long can I one use the pesticides on d nymph

Most pesticides will not kills the eggs.

You will notice after a treatment, another cycle occurs of bites a few days later… likely 5 to 7 days. This is the hatchlings from the eggs and these are the most painful bites. The little nymphs do not have a numbing agent like the larger adults when they bite, so you feel it.

What You Want To Do For The Eggs:

We found a way to get rid of the hatchlings and egg cycle with our residual bed bug treatment. You simply spray Green Bean Buddy bed bug killer on any surface (clothing, bed, boxspring, and around the bed on the floor). This will prevent and kill these pests from reaching you. In fact most will avoid the area of treatment and if hatchlings get near it they die. So we recommend a nice barrier every few days until all the hatchlings are gone.

Let us know if you have other questions and thanks for contributing to the community.

which is the most efficient pestside for bedbugs…Iv treated mine for 6months with no success

Hi Lizzy, it’s a process. I would advise the following steps below. It’s important to do a treatment and stay consistent. The reason of being consistent is because these bed bugs can hide in many locations. So it’s important to treat all the areas. To combat this difficulty, you may wish to consider a residual bed bug treatment spray. This allows you to spray the areas, then it leaves a clear residual to protect from re-infestations. This is how health facilities, resorts, and pest managers are using the bed bug treatment sprays.

I think one reason they been around for 6 months is you may not know the true source of the problem. This is very common. We’ve found the bed bugs hiding in picture frames way up on the wall. Then other times they were in electrical outlets. And of course… neighbors or when you travel on public transportation. They literally can hitch a ride.

We had someone who was a mechanic, and they worked in a car which had bed bugs. He didn’t know that they were jumping on his clothes from the vehicle he was working on. So they can come from multiple sources. This is why we have had such great success in residual bed bug spray. The simple fact that is kills and then spray along your doors, windows, walls, bed, couches, linens, etc. This will be like a shield which these bed bugs will either come near and die or simply evacuate due to the formulation.

Steps To Follow & Products To Use:

1. Identify what a bed bug looks like – so you can identify the different sizes of them.

2. Where do bed bugs hide – so you know where to treat.

3. How to treat bed bugs yourself – You can use these procedures during treatment.

Lastly, how to keep bed bugs away permanently with re-treatment. This is because re-infestations can come from external sources.

You can consider a Residual Bed Bug Spray to combat the problem. You may also want to consider a bed bug steamer as well.

Thanks for sharing with the community. Let me know if you have other questions. I think the guides will definitely help, just be consistent and remember when doing a treatment, SPOT TREAT… don’t drench. This will give you more product to use later on just in case you need to re-treat or want to prevent the infestation after its gone.

What Causes Bed Bugs and How to Get Rid of Them

Finding out your home has been exposed to bed bugs is enough to give anyone chills. These pests are notorious for entering a home, spreading quickly, and causing a deep infestation. When bed bugs take up residence in and around your bed, they turn toyouto keep them alive. That’s right — as you sleep, bed bugs pierce your skin and feed on your blood. Sounds awful, huh?

A bed bug infestation can be a nightmare to deal with. Obviously, the best course of action is prevention. But even if you’ve already found a bed bug (or ten), there are steps you can take to get rid of them and prevent them from entering your home again. Let’s take a look at what causes bed bugs, how to tell if you have them in your home, and actionable steps you can take to prevent and eliminate bed bugs.

What causes bed bugs?

Bed bugs are small, oval-shaped pests that feed on the blood of humans and other mammals. The presence of a single female bed bug is enough to start an infestation. In fact, a female bed bug can lay 2 to 5 eggs each day, and as many as 500 in her lifetime (usually 6 to 12 months). Left unchecked, one bed bug could turn into hundreds in a matter of a few weeks. Bed bugs survive solely on blood, and need to feed at least once every 14 days to reproduce but, when necessary, can survive months at a time without feeding.

One of the most common questions asked is “what causes bed bugs?” Unfortunately, the answer isn’t cut and dry. Bed bugs originated in developing countries in Africa and the Middle East but, as overseas travel became more popular, they spread to developed countries like the United States, Canada, and the United Kingdom. After the government banned the use of an insecticide known as DDT, which was effective at killing bed bugs but also harmful to humans, the pests began to spread more rapidly. Bed bugs don’t carry disease and, aside from causing itchy, sometimes painful bite marks, don’t pose a huge risk to animals or humans health.

An infestation of bed bugs is caused by spreading the bugs from one place to another. Bed bugs aren’t likely to latch on to you or your clothing as a way to get from one place to another. Instead, bed bugs tend to attach to items found where people travel, allowing them to spread to where humans live (since they feed on the blood of sleeping humans):

  • Luggage
  • Backpacks
  • Briefcases
  • Mattresses
  • Used furniture

Once the bed bugs have attached to your luggage and arrived with you to your hotel or home, they can spread to any small, dark crevice they can find. They don’t have nests but they do tend to live in groups, especially inside of mattresses, box springs, bed frames, and headboards. In other words, bed bugs want to live where they have easy access to humans to feed off of. Though they prefer to be close to the bed, these nuisances will travel between 5 and 20 feet just to feed on a host.

When discussing the causes of a bed bug infestation, it’s important to dispel some of the myths that have perpetuated a stigma around having them.

  • Myth #1:Bed bugs are caused by unclean living conditions— This is absolutely not true. Bed bugs can be found anywhere people sleep or travel, from a 5-star hotel to an airport to your cousin’s odd-smelling basement. Cleanliness is not a factor.
  • Myth #2: Bed bugs spread from person to person— This isn’t entirely false but it’s not exactly true, either. Bed bugs don’t fly or jump like ticks and fleas do, and they tend to stick to more efficient modes of travel, like latching onto your suitcase.
  • Myth #3:Bed bugs can stay contained in one apartment— If you live in an apartment building, you may not realize that a bed bug infestation for your neighbor could be an infestation for you, too. Bed bugs can travel through peeling wall paper, electrical outlets, and practically any other opening in a wall. If your neighbor has an infestation, you should treat for bed bugs right away.

Now that you know what causes bed bugs to infest your home, let’s look at ways to prevent bed bugs.

How can you prevent a bed bug infestation?

In an ideal situation, you won’t ever have to deal with bed bugs in your home or apartment. The best way to ensure this is to take proactive measures. If you live in an apartment, multi-family unit, or have roommates, this may prove more challenging but it’s worth taking as many preventive steps as possible.

Prevent bed bugs when traveling

Travel is one of the quickest ways to bring a family of bed bugs into your home. Whether you’re staying in a hotel, a hostel, or an Airbnb, it’s important to follow these steps to make sure no bed bugs find their way onto your luggage or other personal belongings:

  • Inspect the room you’re sleeping in— Check for live bugs, rusty spots from where bed bugs were crushed, excrement droppings, eggs, and yellowish skins from shedding nymphs. If you find bed bugs or signs of them, let management know immediately. They are legally required to address an infestation and provide you with alternative sleeping arrangements.
  • Keep your suitcase out of the room until you’ve checked for bed bugs— It’s best to keep it in your car or in the bathroom with the door closed. If there are bed bugs in the room, they won’t have access to your luggage and won’t be able to make the trip home with you.
  • Keep luggage off the bed and off the ground— Even if you don’t find evidence of bed bugs in your room, they can travel from other hotel rooms. Keep your suitcase and other bags on a luggage rack or on top of a table.
  • Wrap suitcases in plastic —Airports are full of luggage from around the world which means that they can also be full of bed bugs. For extra prevention, get a plastic suitcase cover.
  • Wash clothes in hot water when you return from travel —Even clothes you didn’t wear should be washed in hot water and dried in a dryer on high heat. If there were any bugs present, this will help kill them and prevent them from finding their way into your bedroom. When moving your clothing to the laundry room, be sure to put it in a plastic bag first, so bed bugs don’t fall off on the way.
  • Inspect and vacuum your luggage when you get home —Before bringing your suitcase into your home, inspect it for bed bugs and vacuum it out, just to be safe.

Prevent bed bugs when moving

When you’re moving to a new home, it’s important to take precautions to make sure bed bugs aren’t transferred from one place to the next, or left behind from previous residents.

  • Inspect your new home for bed bugs— Do this before you move any of your belongings in. Make sure to check the places we listed above. It’s also a good idea to ask the previous residents if they’ve ever had a bed bug problem.
  • Don’t use blankets or coverings from the moving company— There’s no guarantee that the moving company has taken proper measures to check for and remove bed bugs from blankets or furniture coverings. Since these items touch many other peoples furniture and homes, it’s best to avoid using them at all.

Prevent bed bugs at home

If you’re not careful, you may make it easy for bed bugs to enter your home. Fortunately, there are some ways you can prevent bed bugs from coming into your home.

  • Apply caulk to cracks on the inside and outside of your home
  • Make sure window and door screens don’t have any tears
  • Eliminate clutter that makes it easy for bed bugs to hide
  • Use special bed bug coverings to protect your mattress and box spring
  • Keep electrical outlets covered when not in use
  • Vacuum frequently
  • Seal any cracks around baseboards and electrical outlets, to prevent them from moving between walls (especially important in apartments or multi-family homes)

Other tips for preventing bed bugs

  • Be cautious of second-hand items —Previously used clothing, mattresses, luggage, and furniture can host bed bugs and cause an infestation in your home. It’s best to avoid second-hand items that could contain bed bugs. If that’s not an option, be sure to inspect and clean each item thoroughly, before bringing it into your home.
  • Watch for bed bugs in shared laundry rooms —Usually, if an item that has a bed bug on it is washed, the bed bug will die. Still, it’s possible for shared laundry rooms and laundromats to have bed bugs that hideaway. Inspect your laundry after washing, just to be sure.
  • Ask for your apartment’s bed bug policies —If you live in an apartment, there may not be much you can do to prevent bed bugs from infiltrating your apartment. Ask your landlord or management company for a copy of their policies regarding how they handle bed bugs.

Prevention is key if you want to avoid the frustration and stress of dealing with a bed bug infestation. If you’re late to the game and think you may have bed bugs, don’t worry. There are some simple ways to identify the problem.

How to tell if you have bed bugs in your home

If you have even the slight suspicion of a bed bug infestation in your home, it’s important that you treat it. Low-level infestations can be harder to identify and are certainly inconvenient but are easier and much less expensive to treat than a widespread infection. When searching for bed bugs in your home, you’ll want to have a magnifying glass, a flashlight, and a bag to hold any bed bugs you find handy.

Many people believe that bites on the skin are a good indicator of a bed bug infestation but this isn’t always the case. Bed bug bites can look similar to many other kinds of insect bites, as well as eczema, rashes, or hives. Additionally, not all people react to bed bug bites.

Physical evidence of bed bugs

  • Live bed bugs
  • Reddish, rusty looking stains on bed sheets or the mattress (this is caused by bed bugs being crushed)
  • Dark spots that look like a stain from a marker (these are bed bug excrements and can bleed in the same way a marker would)
  • Tiny eggs and eggshells
  • Pale yellow skins (the nymphs, or baby bed bugs, shed these as they grow)

You should also know where to look for bed bugs, aside from obvious places like the mattress. Bed bugs can hide in almost any small, dark space. If you can fit a credit card into a space, a bed bug can fit, too.

Places to check for signs of a bed bug infestation

  • Near the seams and tags of the mattress
  • Inside or on the box spring
  • In cracks on the bed frame and headboard
  • Under loose wallpaper
  • Inside or behind picture frames or wall decor
  • In the joints of drawers and shelving
  • In the crevices of where the wall meets the ceiling or the floor
  • In electrical outlets

You don’t have to rely on seeing a bed bug to know for sure that you have an infestation. Seeing their excrements, skins, eggs, or spots is enough to alert you to a problem. If you see a bed bug or signs of bed bugs, you should call a professional immediately. Even if you’re not 100% sure, it’s better to be safe than sorry. It’s easy to misidentify the signs for something else and the longer an infestation is left untreated, the more it will spread.

How to get rid of bed bugs in your home

If you’ve identified that you have bed bugs, it can be overwhelming to know where to start and how to handle the situation effectively. Don’t worry — there are proven tactics for dealing with a bed bug infestation. With each step, you’ll want to be as strategic as possible because it’s very easy for bed bugs to spread to other areas in your home. If you live in an apartment, contact your landlord immediately; they may be legally required to help with treatment.

Keep the infestation from spreading

The first thing you’ll want to do when you begin the process of getting rid of bed bugs is to avoid the infestation from spreading throughout the house.

  • Placing everything in the infested room in a sealed plastic bag until it can be treated.This includes bedding, clothing, stuffed animals, blankets, toys, and any other items that could contain bed bugs.
  • Discarding furniture that you can’t remove bed bugs from.Make sure to destroy it or mark that it has bed bugs so someone else won’t bring it into their home.
  • Vacuum thoroughly and empty the vacuum bag after every use.You’ll also want to throw the vacuum bag away in an outdoor trash can.

Once you’ve ensured that the bed bug infestation is contained to the original area, you’ll want to start preparing for treatment. The Environmental Protection Agency (EPA) warns, “Jumping straight into control is tempting, but won’t work. Preparing for treatment is essential to getting successful control. It will also help by making it easier for you to monitor for bed bugs that haven’t been completely eliminated. This preparation should be conducted whether you are doing the treatment yourself or hiring a professional.”

Preparing for treatment against bed bugs

There are several steps you should take to get ready. These include:

  • Remove all clutter from infested room— Bed bugs love to hide out in clutter, so the less there is, the easier it will be to exterminate them. As you remove clutter, be sure to put it into sealed plastic bags and remove from the house so you don’t spread the bugs to another room
  • Move your bed away from the wall— You should move your bed at least 6 inches away from the wall, remove all bed bugs and eggs from your bed (you may need a professional to help with this), and use bed bug interceptors to catch any pests that try to climb up your bed.
  • Clean all items in the infested room —This includes walls, furniture, baseboards, clothing, decorations, curtains, and anything else that is in the room. As you clean, remove any bed bugs, eggs, or skin that you find and dispose of in a sealed plastic bag. Vacuum thoroughly and place the vacuum bag inside of a sealed plastic bag and then into an outdoor trash can.
  • Make necessary repairs— Because bed bugs like to hide in small places, it’s important to inspect the room for any cracks in the wall, floor, or ceiling, damage to the electrical outlets, and tears in the wallpaper. Caulk and repair as needed to make it impossible for bed bugs to live there.

Finally, you’ll want to take steps to kill the bed bugs. Depending on how bad the infestation is, you may want to consider hiring a professional to handle the extermination of bed bugs.

Heat/cold treatment of bed bugs

To kill bed bugs using heat, you can place in a black plastic bag and leave in the sun or in a hot car. Alternatively, you can set your freezer to 0 degrees and leave sealed bags with contaminated items inside the freezer for a minimum of 4 days. While this can be useful for small items, it’s not considered an effective way to destroy an infestation.

Treating bed bugs with pesticides

EPA-registered pesticides that are made specifically to treat bed bugs can be effective. However, these pesticides can be harmful to your health if not used properly. If you have pets or small children, they should not be in the home during or immediately after the use of a pesticide. Make sure to read and follow the instructions on whichever pesticide you choose.

For widespread infestations, your best solution is to call a professional who can provide an intense, thorough bed bug treatment. Whether you treat for bed bugs yourself or hire a pro, you’ll want to be on high alert for several weeks afterward. If you notice any bed bugs or signs of them, your treatment was probably not all the way effective and another may need to be done.

Minimum risk to health, but never easy to deal with

Bed bugs are a dreaded pest problem that can drain your energy and your finances. Thankfully, though, they don’t pose a risk to your health. Still, taking steps to prevent an infestation is your best bet. If you still end up with a bed bug problem, don’t worry. There are ways to treat the issue and prevent them from coming back.

How long does it take for bed bugs to die after an extermination?

Bed bugs are tough creatures. They are resistance to cold and heat between some temperatures and they can live for a long time without feeding. Sohow long will it take bed bugs to dieafter a bed bug treatment?

Bed bugs are tough bugs

They can easily keep living between 45°F and 100°F. Conditions will be harder for bed bugs, when temperature is near to 0°F and more than 113°F.

If they fed once, they won’t need feeding for several months, and maybe for a year in some cases:

They have resistance to any environment in US and can easily adopt where they started to live.

How quick they die after a treatment?

The answer will vary to what is used for bed bugs. You can use some homemade remedies or chemicals or bed bug sprays. They will all have different results from each other.

Let’s look at the effect of bed bug remedies one by one:

Bed bugs will die in different times due to your remedy

As you see above, there is no certain answer for dying process of bed bugs. What you use for bed bugs will determine the death time of bed bugs.


Bed bug are resistant creatures, and it’s not easy to kill them in most cases. Those chemicals or sprays you use for bed bugs are the most effective ways to kill them.

But if bed bugs don’t directly touch with your treatment, they won’t die. So, you must wait for at least a few week in every single treatment to get the result.

Bed bugs will keep moving around and they can contact your spray or dust anytime. When they contact it,bed bugs will die in various timesdue to your treatment way.

Whatever those treatment do, you must always remember that chemicals and other unnatural treatment ways may be dangerous for household and you should be careful with your kids and babies during a bed bug treatment.

My advice is always to hire a professional, if you have a budget for it.

What Temperature Do Bed Bugs Die At?

Bed bugs are one of the many parasites that can plague homeowners. Like most other parasites, bed bugs are small, resilient, and very nasty. The fact that they tend to live in our beds only makes them even more repulsive.

With that being the case, it’s not surprising that people are constantly looking for new and innovative ways to kill, control, and prevent bed bugs. One curious method that we’ll discuss here is temperature.

People rarely think of using temperature for dealing with pests. This is especially true nowadays with the thousands of pesticides, repellents, and pest-control tools available on the market.

Avoiding the unnecessary use of pesticides is always a good idea. Also, it’s important to remember that repellents aren’t always effective. So, especially since these are our bedrooms that we’re talking about, it’s worth asking, “Can heat kill bed bugs?” We’ll answer that question and a lot more in this article.

Are bed bugs temperature resistant?

The short answer is no, they are not. Like any other living thing, bed bugs do die below or above specific temperatures.

The longer answer, however, is that these temperatures are somewhat difficult to reach. In fact, a lot of what you might have read online under “tips and tricks” is actually wrong. There are a lot of people and blogs that cite using moderately cold or hot temperatures to kill bed bugs, which is almost always misleading.

The fact of the matter is that bed bugs can, unfortunately, survive a lot of extreme temperature fluctuations. The temperatures that are lethal to bed bugs often can’t be reached in an average household and can also require additional equipment.

Discovering the actual temperatures needed to kill bed bugs often dissuades people from attempting this method at all. Instead, they’ll turn to pesticides and other traditional methods to deal with their parasite problem.

What temperature do bed bugs die at?

According to various scientific studies, the temperature that is lethal for adult bed bugs is 118.94°F (48.3°C). On the other end of the spectrum, the temperature at which adult bed bugs freeze to death is -19.48°F (-28.6°C).

Although these can be tricky to achieve in a residential setting, it isn’t impossible. Before you consider using temperature as a weapon, it might be good to know which works best: heat or cold. This will depend on the equipment that you have on hand.

Can you freeze bed bugs to death?

Some modern freezers can reach 0.4°F (-18°C), although many freezers come up short in that regard. At normal freezer temperatures (which reach 6.3°F/-14.3°C, on average), bed bugs will die in 24 hours. It would be safest to leave them in there for at least four days, though.

If you want to freeze your unwanted bed bug guests to death, you’ll need:

  • A remote thermometer to verify the temperature in your freezer
  • Bags with airtight seals to store the infected items in (since you definitely don’t want bed bugs crawling around your freezer)
  • Time

That last point may be surprising, but bed bugs can survive in freezing temperatures for quite some time. So, if you want to be certain that your efforts will yield a positive result, be prepared to set aside enough space in your freezer for at least 4–5 full days. Also, remember to put every infected item in a sealed plastic bag to ensure that your bed bugs are confined and can’t escape.

As for the type of things you’ll want to freeze, any item that can survive in such temperatures for 4–5 days can be frozen. Shoes, books, cloth items, toys, pictures, and even electronics without LCD screens can all be put in the freezer and come out unharmed.

If you have bed bugs living in electronics with LCD screens, in items that contain a lot of moisture, or in items that are too valuable to risk putting them in a freezer, you might want to consider another method of bed bug control.

Keep in mind that the length of time is important. Bed bugs have been known to survive temperatures of even -13°F (-25°C) for quite some time. So, you’ll have to make sure to keep them in the freezer long enough to kill them.

How can you use heat to kill bed bugs?

If you want to try heat instead of freezing, you absolutely can. This is often the less practical route for a couple of reasons.

  • Not many homeowners have a suitable way to reach steady temperatures of 113°F (45°C) or of maintaining that temperature for a long period.
  • Few infected items could survive such temperatures for long enough.

Also, remember that the higher the temperature you can achieve, the faster you’ll deal with the problem.

At 113°F (45°C), it takes 94.8 minutes to kill adult bed bugs. The trick here, as with the freezing method, is to make sure that all the bugs are subjected to the heat treatment. You can’t allow a single one to escape and hide somewhere.

For this reason, when using heat, you might want to subject your entire home to this treatment. After taking everything that can’t survive such temperatures outdoors (including yourself).

You should call a pest control company that specializes in heat treatments. They’ll use special equipment to increase the temperature in your home to the required level. This should kill every living bed bug inside – if maintained for enough time. While that is happening, you’ll have to deal with the bed bugs in the items you’ve brought outside in a different manner.

What temperature do bed bugs eggs die at?

So far, we’ve been talking about killing adult bed bugs. We haven’t mentioned what temperatures you need to kill bed bug eggs.

As with other parasites, bed bug eggs are generally more resilient than their adult counterparts. They can survive temperatures that are up to 130.6°F (54.8°C), which is why this is the minimum treatment temperature we’d recommend. As far as freezing is concerned, -46.3°F (-43.5°C) should be enough for bed bug eggs, as long as you give it enough time.



At what temperature will bugs and eggs die in a shorter period of time, say 5 or 10 min? There are some smaller items I don’t want to put in the dry, but I could put in boiling water or in a glass pan in the oven.


I would suggest you try another method instead since I’m not sure what would be the temperature to be lethal in such short timeframe. Here’s our article about getting rid of bed bugs.

My 1987 clothes dryer reaches >130 degree max increment on my gauge. In 2016, I dealt with these bugs several months & rounds of professionally applied pesticides. Now in 2020, exactly 15 days after 1st noticing the aroma of them, & a professional spray, there is not one sign of anything near an egg laying adult. Day 15-20, both myself & 1 of 2 cats have been attacked by hatchlings, followed by finding up to 100-120 eggs that have just dropped from any surface that wasn’t directly treated, ie, underneath a cats fav window seal, around the vacuum cleaner, & under 3 total pieces of antique furniture. The bugs may have entered my home as eggs via cushions on last summers lawn chair that had covers removed, were laundered & kept on the drying cycle around 40-50 min. The fabric did not seem to conduct heat well & they were left in a temp storage area, not quite 2 weeks before re-doing another 30-40 min dryer cycle once, then storing in a vacant room, inside one of those 3 pieces of furniture. My 2 worst ground zero egg drops! The temps on this site prob were never achieved within pores of my cushions. It’s sure cost me to use best available info till I found this page. Which was 112 degrees & 10 min, I’d found in 2016. Now, in 2020 I’ve been just lost in .gov sites that haven’t provided any easily findable info I could use, 1st just searching for kill times & temps. So I thought I’d share, & say THANKS 4 the INFO.
