Can bed bugs live in walls?

Bed bugs are a pest that are nearly impossible to get rid of. They can live almost anywhere as long as they can find a crack or crevice to get into. This means that they can be found living in all sorts of places, including walls.

Bed bugs can live in walls and other crevices. Walls with cracks and crevices provide bed bugs with a safe place to rest during the day so they can feed at night. This is why it is vital to seal up any cracks or holes in your walls to help ensure that bed bugs don’t enter your home.

Bed bugs are, in fact, much more likely to be found in walls that are made of panels, drywall, or walls that are older and worn down. They can also be found in furniture, mattresses, and other areas where they can hide easily.

If you think you have an existing bed bug infestation, it is important to get rid of them as soon as possible.

What are the common signs of bed bugs in or on walls?

Bed bugs are difficult to see and can only be confirmed by using a credit card to slide them out of the cracks and crevices in your walls. They will leave behind blood stains on walls and furniture, as well as fecal matter.

If you notice any of these common telltale signs, it is important to take action right away.

Some obvious signs that you have bed bugs in or on your walls, apart from small blood stains on bedding and bed bug feces, are skin shed and cracks in the wall near your bed.

Additionally, if you notice an increase in bites even when you’re not sleeping in your bed, it’s likely that there are bed bugs present somewhere in your home.

How can you get rid of bed bugs in walls?

If you have bed bugs in your walls, you probably have them elsewhere in the room too!

Bed bugs can be quite tough to exterminate or get rid of, and one of the most common places they hide is in walls.

To treat bed bugs in walls, you will need to spray along the baseboards and other areas where they may be hiding. It is important to be comprehensive in your treatment and to repeat it as necessary.

That said, bedbugs are likely to be living elsewhere in the room, so treating just this part of the room is not a comprehensive plan.

A more effective solution is to completely vacuum the room and get rid of all the bedbug eggs, larvae, and adults. In case of a large bed bug infestation, you will have to treat your entire room or house!

Should you drill a hole in your wall to treat for bed bugs?

No, you should drill holes in your wall to treat for bed bugs.

Bed bugs are notorious for being difficult to get rid of. They can enter any home through tiny cracks and crevices in the walls. Therefore, adding more holes or cracks in your wall is not the best way to deal with bed bugs.

In fact, if you are dealing with a bed bug problem, one of the most important things to do is to treat the entire room.

This will kill almost any bed bugs that are living inside the walls. It is also important to completely seal off any cracks or holes in the wall so that new bed bugs cannot enter.

If you’re looking for some easy ways to get rid of bed bugs in walls, the first step is to install bed bug interceptor traps around the floorboards.

Interceptor traps work by stopping bed bugs from climbing up your legs and getting into your bed. Once you have the interceptors in place, you can treat the wall with a pesticide or heat treatment.

How long can bed bugs live in walls?

Bed bugs need to come out to feed.

Bed bugs can live in walls for a long time, depending on the environmental conditions. In general, they can live for 20-400 days, but this number can be shorter or longer depending on the temperature and humidity of the surrounding area.

Just in case you’re wondering, bed bugs cannot live in walls indefinitely. They need to periodically emerge from the wall to feed and reproduce. If they are unable to do so, they will eventually die.

Can bed bugs live in electrical outlets in the wall?

Bed bugs are unlikely to live inside an actual live electrical outlet. Bed bugs are more likely to reside in the void where the outlet is located. The outlets offer the perfect dark and moist environment for the bed bugs to thrive.

If there is evidence of bed bugs living in your electrical outlets, it is best to call an exterminator to remove them from your home.

Can heat treatment kill bed bugs that live in walls?

A very effective way to treat bed bugs is through heat treatment. This involves heating up the area where the bed bugs are living to a temperature that will kill them.

While heat treatment is effective, it is important to make sure that the area is heated evenly in order to ensure that all of the bed bugs are killed.

In order to ensure that the bed bugs in the walls are killed, your walls will have to be heated to a fairly high temperature.

Otherwise, the bed bugs simply won’t die. Make sure that you discuss with your bed bug specialist how you should proceed. He will be able to advise you on whether or not heat treatment is an option and, if so, how best to proceed.

Can bed bugs travel and move through the walls of your apartment building?

Bed bugs can, indeed, travel through the walls of an apartment building quite easily. If you think that you have a bed bug infestation, it is important to inform your landlord right away so they can take appropriate action.

Bed bugs are notorious for their ability to travel and infest different areas. They can travel through the gaps in wiring and plumbing to infest other units in a building. This means that if you have a bed bug problem, it is important to address it quickly before the bugs spread.

Generally, bed bugs will not travel through the walls of an apartment building if they cannot get food from the target unit. This is because they need blood to multiply, and if they are unable to find a food source, their numbers will dwindle over time.

How to prevent bed bugs from coming through your walls?

Bed bugs are, unfortunately, very hard to prevent from entering your home in the first place. However, there are a few things you can do to reduce the chances of them finding their way in.

For example, you can and probably should seal any cracks or crevices in your walls with caulk or other sealants, and you should also make sure that all of your bedding and furniture is free of tears or rips that could provide them with a place to hide.

Can bed bugs chew their way into your room through the walls?

No, bed bugs cannot chew their way into your room through the walls. Bed bugs can only enter and exit a room through existing cracks or holes in the walls.

They are not designed for chewing through solid material, so they cannot damage your walls, furniture, or other belongings in a room.

Can bed bugs crawl up and down your walls?

Bed bugs can crawl up and down walls. In fact, that is their main way of gaining access to your bed if it’s touching the wall! That said, even if your bed is away from the wall, they may still be able to reach you.

If you are experiencing an ongoing bed bug infestation, it is important to treat them on all surfaces, including walls. 


The fact is that even if you have bed bugs in your walls, you can’t treat only your walls for bed bug infestations. If you have bed bugs in your walls, then it is almost impossible not to have them in the rest of your house. Therefore, make sure you treat your house comprehensively for a bed bug infestation.
