Why Do Bedbugs Infest Walls?

Although they're tend to go towards fabric and warmth, bedbugs are also attracted by wood and the carbon dioxide that people exhale. Plus, walls is a part of numerous hidden spots for bed bugs. They can squirm into picture frames and under baseboards.

These locations offer quick access to human hosts at night – a perfect place to live for bugs that like to feast and then scoot away unnoticed.

Avoiding Detection and Pest Control

It's easier for bed bugs to avoid detection when they hide in accessible spaces like crevices and small holes. It helps them survive pest control treatments which typically focus on more obvious infestation spots like furniture, behind beds, or under mattresses.

Essentially, they're following the old saying "Out of sight, out of mind."

And while they prefer fabric or wood over plastic and metal, they don't discriminate much when it comes to a good hiding spot. They've even been found in light switches and electrical outlets. When you get into bed after a long day, these walls can turn into a launchpad for a bed bug attack, urging you to regularly vacuum around your room to keep them away.

How to Detect BedBugs on Walls?

Intriguingly, bedbugs can easily creep into anything and snugly fit into tiny crevices in your walls. It's crucial to understand the hints in order to detect them.

Visual Indicators

Visual clues often serve as the first hint of these tiny invaders. The presence of small, rust-colored stains on surfaces, usually indicative of their excreted blood, stands out as a glaring sign. Their eggs, deposited closely around can be another key identifier.

Inspecting Your Walls

A methodical inspection, digging deeper into these signs, can help confirm the problem. Using a flashlight or a magnifier, you may find they've embedded in crevices or left behind mini mounds of cast-off skins. It's advantageous to search around the corners, near baseboards, and behind items hung or leaning against the wall.

Common Areas for Wall Infestations

While these pests can infest large areas of walls, certain spots offer them more benefit. Here are the most common areas around your walls:

  • Behind Picture Frames: In our experience, picture frames attached to the wall have often provided a perfect shelter for bedbugs. So, it's a good idea to remove frames carefully and inspect the backside, joints, and hanging wire for bug activity.
  • Electrical Outlets: Another hot spot is an apartment's electrical outlets. Bedbugs can slip into the outlet holes and stay protected from most treatments, making them a tricky area to handle.
  • Baseboards: Similarly, baseboards where the wall meets the floor often contain cracks exploited by bedbugs for hiding. It's common to find signs of their activity, like eggs or skins, along these spaces. A timely check can reduce the chances of a bathroom bed bug infestation, helping with effective pest control.

DIY Prevention and Extermination Strategies

Although expert assistance shines in eliminating a bed bug infestation, it's practical to deploy home remedies as immediate countermeasures. Our contribution focuses on home remedies and DIY solutions that can help hinder bedbug invasions on walls and prevent their spread.

Home Remedies and DIY Solutions

Battling bedbugs involves diligence, such as carefully sealing infested items in a bag before disposal to prevent spread. Here, we provide a few home remedies and DIY tactics that can prove effective, complementing professional treatment strategies.

Note: Home remedies can also include inspecting luggage thoroughly after traveling to prevent bringing new infestations home.

Sealing Holes

Bed bugs have a knack for hiding in the smallest spaces within walls like cracks and crevices. In control methods, sealing them assumes priority. Use a sealant or caulk to close these spaces and make your walls less inviting for bedbugs. Close scrutiny for tiny openings around baseboards, window frames, and electrical outlets aids in catching hold of potential hiding spots.

Installing Barriers and Interceptors

Bed bugs moving from your walls onto your furniture makes for a bigger problem. Interceptors play a key role in controlling infestations, creating physical barriers that prevent bedbugs from climbing onto beds or sofas. Install these interceptors under furniture legs—they trap bed bugs and stop their movement. Regularly check these traps to assess the severity of the infestation.

Using Diatomaceous Earth

Diatomaceous earth (DE) is one of the best bed bug killers. It's harmless to humans but lethal to insects. Apply DE in areas where bed bugs hide, typically in wall cracks or near baseboards. When applied properly, DE dehydrates bugs and fatally damages their exoskeletons.

Professional Extermination Methods

Whether bed bug infestations have taken over walls, floors, mattress seams, or furniture, dealing with these uninvited pests often requires expertise. Comprehensive approaches and specialised tools often make extermination procedures carried out by exterminator more effective than DIY treatments.

When to Call an Exterminator

Pest management isn't always a simple task; it often starts with a thorough vacuum of suspected areas. A thorough understanding of the riding parameters - the precise, accurate measurement of the pest issue - dramatically influences pest management outcomes. Oversights during infestation assessments might hide signs of bed bugs behind wall cracks, within clothing, or in dark corners, making a big problem look small.


Sneaky as they are, bed bugs can take up residence in walls, infesting even the smallest spaces. Known for their adaptability and preference for seclusion, these pests pose a significant challenge in pest control.

Remember you're not alone in this battle. Pest control services are just one call away. Their competence and experience will go a long way in getting rid of bed bugs from your space for good. So keep your eyes open, be informed, and let's beat the bugs together.
