Hidden Pests in Your Walls — What You Don’t See Can Hurt You

You might believe that your home is safe and clean. But pests that are hidden inside your walls could be living there and causing damage. Most of the time, these pests are quiet and sneaky. They stay in dark places or come out at night.
Things might get really bad by the time you notice them. Being aware of these pests can help you do something before things get worse.
Termites: Quiet but Dangerous
Termites are one of the worst pests that can come to your home. They live in walls and under floors and eat wood. You will not see them very often. They are there, though, if you hear hollow-sounding wood or see mud tubes along the walls.
These insects eat all the time. They do not stop. They can damage wooden beams and make a house dangerous if they are not found quickly. These pests can not get into your home if it stays dry, and any cracks are sealed.
Bed Bugs: Hiding in Cracks and Seams
Bed bugs are very small bugs that feed on your blood while you sleep. They hide in wall sockets, bedding, and furniture seams. They move fast but do not fly or jump.
You may have red, itchy bumps in lines or groups when you wake up. It is hard to get rid of them. Sprays do not always work. Bed bugs are hard to catch because they can hide in small spaces and spread quickly.
Unseen Roommates: Cockroaches, Beetles, and More
One of the most hated pests is the cockroach. They hide in places that are damp and dark, like behind walls, near pipes, and under sinks. You might get sick from these insects. They spread germs that can make allergies or asthma worse, especially in kids.
There may also be ladybugs or boxelder bugs on your walls. Even though these insects are not dangerous, they still have no place inside. They can not get in if you seal up cracks and keep your house clean.
Summer Brings More Trouble
During the warmer months, more pests come out. Ants begin to look for water and food. Flies buzz around trash and food scraps. Mosquitoes lay their eggs in still water. Pests look for cooler, safer places to live, and they may find their way inside your walls. These animals leave droppings, chew on wires, and spread diseases. A lot of people do not notice them until wires spark or a pipe leaks.
Here is a quick list of the most common hidden pests:

Why Pests Love Walls
Walls provide pests with what they require: darkness, warmth, and safety. Wall holes are great places to nest. It is easy to get around the house because of the pipes and wires. They can get in without being seen if there are gaps around windows, doors, or vents. As soon as they get inside, they start to multiply quickly.
Pests like termites and carpenter ants can ruin the building. Some pests, like rodents, chew on electrical wires. This might even start house fires. Cockroaches, bed bugs, and some beetles are more of a health risk because they bite, spread germs, or cause breathing problems.
