How Do Bed Bugs Spread In Apartment Buildings

Can bed bugs travel from apartment to apartment?

As you probably know, bed bugs are expert travellers. They can hide in luggage, clothing, and other belongings to find new homes across the street, across town, or even across the country. With that in mind, it should come to know surprise that they absolutely can travel from one infested apartment to other neighboring units.

Bed bugs can enter the walls of an infested room via light switches, electrical outlets, and pretty much any cracks or voids present. Remember, they can squeeze into any space thick enough for a credit card to fit. Once in the walls, bed bugs can easily travel along electrical wires and plumbing pipes to reach other rooms, or even other apartments.

It’s this ease of spreading that makes apartments such vulnerable targets for bed bugs. It’s an uphill battle, but fortunately there are steps that can be taken to reduce the likelihood of an infestation coming from your neighbors:

  • Apply a residual powder, like diatomaceous earth or CimeXa, to your walls, baseboards, and door frames. This will act as a long-lasting defense against bed bugs that try to enter your apartment. Be sure to wear gloves and use a professional powder applicator.
  • Use bed bug proof mattress and box spring encasements, as well as ClimbUp Interceptors, to safeguard your bed against wandering bed bugs looking for a meal.
  • Use a portable bed bug heater, like a ZappBug or ThermalStrike, to heat-treat your belongings after travelling, or when you suspect that you have infested items. This is a great way to not only ensure that you don’t have to deal with an infestation, but to protect your neighbors from a potential pest problem as well.

How Fast Can Bed Bugs Spread?

Silent Pests

Bed bugs have been in the news in recent years.After decades in which they seemed to have been almost eradicated, these pests are making a comeback. This is bad news for humans. According to the College of Agriculture at the University of Kentucky, bed bugs require a “blood meal” to survive, and they prefer the taste of human blood to that of other warm-blooded animals. These miniature vampires typically strike at night while people are sleeping, making a painless bite and sucking several drops of blood. Not known to carry infectious diseases, bed bugs nonetheless can cause allergic reactions to their saliva, and their bites leave itchy blotches similar to mosquito or flea bites. Hiding in inaccessible places, spreading out to all areas of a building and able to go months without feeding if necessary, they are difficult to find and control.

Once an infestation is underway, the property owner faces a tough eradication process that will require the services of a professional exterminator.This must be done sooner rather than later because they are hardy and they spread very quickly.

Reproduction

In the outdoors, bed bugs infest nests of birds, bats and other animals.These flightless insects, which measure 1/4 inch at maturity, enter a house, motel or apartment building by hiding in luggage, clothing or fabric. Once in place, the bugs set about reproducing, which they can do with impressive speed. Female bed bugs lay between one and five tiny eggs per day. Hatchlings are no bigger than a poppy seed.Once hatched, according to the School of Public Health at Harvard University, a baby bed bug or “nymph” requires only a single blood feast to molt and move into its next stage of development, which occurs five times before adulthood.

The nymphs reach maturity in a month or more, depending on conditions such as temperature (bed bugs like it warm) and the availability of blood. Assuming an average daily production of three viable eggs, simple math would indicate that at the end of one week, a single female would lay more than twenty eggs. Some weeks later, given a steady blood supply, these 20 bedbugs are adults. If half of them are females and each one lays twenty eggs in a week, this means a second generation of nymphs numbering approximately 200, all of which come from just one female bed bug. The production of three generations of bed bugs in a year is not uncommon.

Locational Spread

Bed bugs can spread from one room or apartment to another through door frames, windows, or holes or cracks in the walls, ceilings and floors. They can contaminate wood furniture by laying eggs in cracks and recesses, and when that furniture is moved, these eggs (which can stay viable for years) may hatch in a new location. Weeks or months without blood do not harm these tough insects.As a result, if bed bugs are found, one should consult an exterminator immediately.

Bed bugs and your apartment

Bed bug problems are becoming more common in apartment communities. More than ever, it’s important for tenants and landlords to understand these insects and what it takes to eliminate them from apartments.

What are bed bugs?

Bed bugs are tiny insects that live by feeding on human blood, usually at night. They are secretive, hiding in cracks and crevices during the day, and coming out at night to feed. The bite of the bed bug is painless and may or may not leave a red mark or itchiness.

How do I know whether I have bed bugs?

Bed bugs are small, and come out mostly at night.

Because of their small size and painless bite, bed bugs may initially go unnoticed. If you notice that you are waking up with itchy welts, see tiny red spots on bedding, or think you have seen the bugs, you may have a problem. Bed bugs do not have nests, but will congregate in choice hiding places. These areas may be marked by tiny dark spots and stains, and may have a sweetish odor.

Will bed bugs hurt me?

Fortunately bed bugs are not known to carry any diseases to humans, although some people may experience irritation or allergic reactions to bed bug bites. Mostly bed bugs are considered disgusting and can be a source of stress and concern for people living in infested apartments.

How do bed bugs get into my apartment?

Bed bugs are no longer an unusual pest in apartments. Since approximately 2000, bed bugs have reemerged as an important pest in the United States. Bed bugs are occasionally introduced into an apartment via luggage that has become infested from a hotel or hostel. In apartment complexes, it is probably more common for bed bugs to enter a home from a nearby infested apartment, during moving, or through picking up used or recycled furniture or mattresses. Once introduced into an apartment building, bed bugs can readily spread from one infested unit to another.

What should I do if I suspect bed bugs?

If you think you see a bed bug, capture it if possible. Place in a leak-proof container, preferably with a little rubbing alcohol, and show it to your apartment manager to confirm its identity. Even if you cannot capture one of the insects, you should inform your building manager if you suspect you have a bed bug problem.

If I have bed bugs should my neighbors be treated too?

When beg bugs are found in one apartment unit, it is considered standard practice in the pest control industry to inspect all apartments surrounding the infested apartment. If no bed bugs are found, surrounding apartments do not necessarily need to be treated. But if an adjacent apartment is found infested, it should be treated and all adjacent apartments should also be inspected (see next question).

How do you get rid of bed bugs?

If you live in an apartment or condominium, it’s best to alert the property manager right away (preferably by phone and in writing). In multi-family housing a manager-coordinated bed bug control effort using a pest control company is generally needed. Bed bugs readily move from apartment to apartment, with many people unaware that they have a problem, so chances are that you will not eliminate a bed bug problem by yourself. If one apartment is infested, adjoining units (left side, right side, above and below) should be assumed to be infested unless shown otherwise through inspection or monitoring.Simply asking tenants whether they have bed bugs is not enough. In one study only half of residents in a large apartment with bed bugs knew (or admitted) they had a bed bug problem.

Bed bug treatment consists of a thorough inspection followed by vacuuming and treatment of all detected bug hiding spots. Treatment is labor intensive and may take several hours per apartment. It will also probably require several visits and treatments to permanently get rid of a bed bug problem.

My landlord wants to treat the problem using in-house janitorial staff. Is this OK?

In Texas, multifamily housing, hotels, or any business providing lodging must be treated for pests by a licensed pesticide applicator. So unless the apartment employee who enters your home to control bed bugs is licensed by the Texas Pest Control Service, this would be illegal. Illegal activity by an unlicensed person includes the use of over-the-counter pesticides, heat treatment or any other non-chemical control methods–anything intended to control pests like bed bugs, cockroaches, mice, etc.

What’s my responsibility?

As a tenant, your first responsibility is to report any suspected bed bug problem immediately. Once an appointment is made for your treatment, it will be your duty to prepare your apartment. The following tips will help your pest control service and YOU to get rid of bed bugs quickly.

  • Don’t move any of your things to another apartment during or before the treatment. You might end up spreading bed bugs to the other apartment and may re-introduce bed bugs to your newly-treated apartment later, when you retrieve your belongings.
  • Pick up and double bag all loose items in bedrooms and other rooms to be treated. Clutter makes it difficult for maintenance crews to inspect all parts of your apartment, and gives bed bugs more places to hide. Before returning these items, follow your pest control company’s instructions for cleaning and inspecting to make sure you are not returning bed bugs to the treated room.
  • Clothing that may be infested should be double-bagged prior to treating the room, and dis-infested before returning to the room. Recent research shows that dry cleaning, washing in hot water, or tumble drying for 30 minutes on high will kill all stages of bed bugs.
  • Even though bed bug treatments are mostly focused on bedrooms and living rooms, it’s still a good idea to put away all food in the kitchen and dining areas, and cover tables, counters, etc. to protect from contamination. Although your pest control professional will be careful, and the chemicals used should pose minimal risks to people, this step will reduce your risk of unnecessary pesticide exposure and reduce costs for maintenance staff.
  • Unless you intend to get a new bed anyway, it’s not very effective (or economical) to discard your mattress, box spring or bed. Instead, buy a good quality, bug-proof mattress encasement. Encasements are special sacks that fit over a mattress or box spring–usually to reduce allergens. The zippers onbed bug-proof encasementsare designed to be tight enough to prevent even the smallest life stages of the bed bugs from escaping. Also, truly bed bug-proof encasements are strong enough to prevent bed bugs from biting you through the encasement. A good encasement will trap all bed bugs in the mattress and box spring inside, and will be smooth on the outside, providing few places for bed bugs to hide. Sears, Target, Walmart and other stores may sell bed bug-proof encasements, but they can also be purchased online. Look online for different brands and reviews of mattress encasements, using the search term “bed bug mattress protectors”.
  • Vacuum couches, chairs and recliners thoroughly before pest control service. Many bed bugs in apartments are found in couches and upholstered chairs. Double-bag and discard the vacuum bags in an outdoors dumpster immediately to avoid reintroducing or spreading any bed bugs caught in the vacuum.
  • Don’t forget to empty drawers in nightstands and dressers next to beds prior to treatment. This will make it easier for the pest control company to inspect and treat these furniture items. Bag and clean or inspect these items according to the directions of your pest control professional before returning the items to the treated furniture.

It’s essential to cooperate with management and with your pest control professionals to get complete bed bug control. Once established, bed bugs can be difficult to control, especially without the help of tenants like you.

How bed bugs spread through apartment buildings

Share this Article

The Journal of Economic Entomology has released a chilling case study of a massive bed bug infestation in a high-rise Indianapolis apartment building.

It’s a Ghost-of-Christmas-Future story for landlords, co-ops and condos interested in avoiding, say,a $250,000 bed bug clean-up bill.

You can download the study at the bottom of this post. Here’s a quick summary of the cautionary facts.

  • Nearly half of this 210-unit, 15-story low-income apartment building became infested within 41 months of the original problem, which likely started with a single resident who moved into a 12th floor apartment.
  • 50 percent of infested residents were completely unaware that they had bed bugs
  • Visual inspections alone failed to detect nearly half of the infestations.
  • The most reliable detection method was the placement of dish-like bed bug traps, aka “interceptors," under furniture legs.
  • Infested apartments tended to be right next door to each other (53%) or across the hall (45%).
  • Bed bugs frequently walked out of the front door of one apartment and into another on the same hallway.
  • Bugs were also spread through the building when infested furniture was discarded without wrapping it in plastic, by neighbors visiting infested apartments or infested common areas, and by an infested wheelchair used in common areas.

The study’s authors point out that financial constraints prevented these low-income residents—some of whom lived with infestations for two years—from taking some bed bug fighting measures like encasing mattresses, laundering clothes frequently, and replacing heavily infested furniture.

“Unfortunately, this population can pose additional challenges which are not indicative of all buildings,” notes BrickTank pest management expert Gil Bloom, who brought the article to our attention.

“However, the study certainly does underscore a need for a systematic approach to managing bed bugs,” says Bloom, the vice president of Standard Pest Management and a member of Mayor Bloomberg’s Bedbug Advisory Board.

Where Do Bed Bugs Come From – How Do You Get Bed Bugs

How do you get bed bugs in your house? Anyone who has ever woken up with a chain of red blisters from the bites of night parasites would wonder where bed bugs come from. In most cases, bed bugs are not transferred to the apartments. The thing is that they live there for decades, not revealing their presence at once. Mostly these insects spread from one apartment to another, but where do bed bugs come from?

It is impossible to answer this question because they just spread through the building being attracted by the presence of humans. How do bed bugs get in bed? After penetration into the premises, insects hide under the beds, in the wardrobes, under the carpets, behind the baseboards, in the cracks of furniture and in mattresses. These insects prefer to settle in places where they can bite people during night time.

In suburban areas bed bugs find human dwelling using their sense of smell. Then insects move to the buildings from chicken coops and rabbitries, where they parasitize on the skin of medium-sized animals. However, bed bugs parasitism on other mammals and birds is more like an exception, because these insects usually feed on human blood.

Bed bugs are not very mobile insects. They cannot fly and run much slower than cockroaches, but they can survive without food for quite a long time. Thus, bed bugs can travel for long distances. How do bed bugs spread? Despite the fact that these parasites cannot run fast, they spread through the apartment considerably quickly. They move freely through ventilation holes, electrical wiring channels and cracks in doors. Due to flat shape of their bodies these insects are able to crawl even where no cracks or holes are visible. It is impossible to isolate an apartment from bed bugs because they come through the outlets and by the outer walls through the windows. It is especially true for the apartments in old high-rise buildings and the houses built in the countryside.

How Do You Get Bed Bugs in Your House

First, people get bed bugs by bringing them home from journeys. For example, bed bugs can be in the luggage and the things brought from the trips, to the warm countries in particular. Tropical Egypt, Thailand, Indonesia and India seem to be a paradise for thermophilic bed bugs. Thus, travelers have to remember that the last place they traveled to before the bugs appearance is the most likely to be a historic homeland of the blood-sucking parasites. In this case, you can bring a single adult female that may lay eggs and give rise to a new population. You should be cautious because these insects can hide or accidentally fall into the pleats of the clothes, into the suitcases, bags and footwear, and travel through several time zones. This way of getting bed bugs is particularly relevant for backpackers, who often change hotels.

One more common method of how bed bugs come to the new house is hiding in the furniture, especially in the new one. In furniture factories or stores bugs have nothing to eat; thus, new products are not infested. Pieces of furniture from infested houses and apartments are, on the contrary, the main breeding ground for these parasites.

People can also get bed bugs on clothes. Although these insects prefer to bite open skin areas, they often hide in the clothes left in the apartment or taken off before going to bed. Thus, you can bring bugs into your house by visiting the infested house or taking guests from such a place. Moreover, there are known cases when bed bugs were found in expensive clothing shops in unworn clothes. The insects got there from people who lived in the infested apartments or from neighboring premises.

Furthermore, bed bugs can get into the house with new appliances. These insects prefer to spend the daytime in warm places. Thus, they can stay in laptops, tablets, scanners, microwave ovens, and any other appliances, and be transferred to a new place from the store.

Moreover, bed bugs can get into the apartment being carried by animals. It is a very rare way of transferring these insects, but it may happen too. Despite the fact that bed bugs do not feed on cats and dogs because they cannot bite their skin tissue, these pets can transfer the parasites. Moreover, bats and birds can be transmitters of these parasites as well.

Thus, once appeared in the house, bed bugs can spread through the entire apartment. They can inhabit all the places where they can be caught only by the professional desinfectants. Moreover, bed bugs can fall into anabiosis because of the absence of food. Thus, the bugs can stay in uninhabited apartments for more than a few months. A flat can be perfectly clean at first glance, but insects and their larvae will crawl out of the cracks as soon as they smell a human body.
