When most people hear the word bed bugs, they think of pests that live on and around mattresses. In reality, you can find bed bugs in walls, carpets, furniture, and other items in the home. Bed bugs are known to reside in walls where they can stay hidden and out of sight from humans but still close enough to easily find a meal. This fact is important to have an effective bed bug treatment.

Bed bugs hide in crevices and cracks in the walls, between floorboards and baseboards, behind outlets and other electrical devices, inside mattresses, and in any other place that offers a hiding spot. The most common places for bed bug infestations are bedrooms due to their proximity to beds, but these pests can also infest living areas, office spaces, and other parts of the home. Bed bug infestations in walls can be difficult to detect because of their small size and hiding ability.

How Long Can Bed Bugs Live in the Walls?

Bed bugs can't survive in a sealed environment like walls forever, as the bed bugs removal agency claims. They need to come out and feed on blood every few days. Without feeding, bed bugs can live for up to a year, depending on the temperature and humidity. They can live longer in warm, humid areas, whereas in cooler, drier environments, they won't last as long.

What Causes Bed Bugs to Move into Walls?

Although bed bugs are often associated with dirty bedding and cluttered homes, they can live anywhere there is a food source. This includes cracks and crevices in walls. Bed bugs are attracted to walls because, as stated, they offer a safe place to hide during the day and easy access to their food source at night.

If the infestation is large enough, bed bugs may travel through walls to search for a new host. Bed bugs can also spread from apartment to apartment if they find an opening, such as a pipe or electrical wire that runs between units.

How to Know if You Have Bed bugs in Walls?

It's difficult to spot bed bugs in walls due to their small size and ability to hide in tiny cracks and crevices. Some use credit cards or any thin material to check for bed bugs in walls. Since bed bug and credit card are almost the same size, putting credit card in crevices and cracks can tell you if there are bed bugs in your walls.

Bed bugs are small, brownish-red insects that feed on the blood of humans and animals. They are usually active at night and hide in cracks and crevices during the day. You may also suspect you have bed bugs in your walls if you find small, dark spots on walls or furniture, which are likely bed bug feces. You may also see small, brownish eggs in these same areas.

Also, if you find small, dark-colored bugs crawling on walls or furniture, it could signify bed bug infestation. A musty odor can also indicate bed bugs, as they release a certain smell when disturbed. Bed bugs tend to emit a musty odor that some people describe as being similar to the smell of coriander.

Bed bugs and cockroaches are two different pests, and there's a myth that seeing cockroaches in your home means you have a bed bug infestation as well, but this is not true. Although cockroaches eat bed bugs, it is not a sign that you have a bed bug infestation, and you should check for other signs.

If you suspect that your home has a bed bug infestation, it is important to contact a professional pest control company as soon as possible. They can use specialized methods and equipment to effectively get rid of the problem and help stop it from spreading.

How to Get Rid of Bed Bugs in Walls?

There are two types of bed bug treatment in walls: chemical and heat treatments.

Heat treatment:

Bed bugs hate extreme heat, so one of the most effective ways of getting rid of them is to use heat treatments. This involves raising the temperature inside the home to around 120 F for a few hours. The heat will kill any bed bugs that are present in the walls as well as their eggs. Professionals can use heat treatment, or you can rent or buy equipment that will do the job.

Steam cleaning is another effective way of removing bed bugs from walls. This process involves using a steam machine to spray hot steam onto the affected areas. A vacuum will help but steaming will penetrate deep into the walls and kill any bed bugs present.

Chemical treatment:

Another effective way of getting rid of bed bugs in walls is with chemical treatments. Chemical treatments involve using insecticides to kill bed bugs and their eggs hiding in the walls.

It is important to note that a professional should only do chemical treatments. Due to their toxicity, insecticides can be dangerous if not used correctly. Professional exterminators can use special equipment and techniques to treat hard-to-reach areas safely and get rid of the infestation.


Bed bugs in walls can be a difficult and annoying problem to deal with. However, with the right methods and techniques, you can get rid of bed bugs in your walls safely and effectively. Heat and chemical treatments are two effective ways to remove bed bugs from walls, but it is best to have the work done by a professional pest control company. With the help of professionals, you can get rid of bed bugs and keep them from returning!
