Pests that Thrive in High Summer Humidity (And How To Avoid Them)

When it comes to a love of humidity, humans and pests are on opposite ends of the spectrum.

While we tend to despise air that is thick with heat and water vapor, most bugs actually thrive in it and need it to live.

Unfortunately, this means that the impending summer humidity in certain parts of the country is about to bring these pests out in a big way.

Five of the most common summers pests

1. Cockroaches

The German cockroach is the most common roach species infesting our homes in North America. They are attracted to warm and humid places, making your kitchen and the water heater in the basement their most frequented hideaways.

2. Silverfish

These small, wingless insects are nocturnal and need to keep their bodies moist at all times in order to survive. You are likely to find them beneath boxes or furniture in your basement, the shower, or hiding in your kitchen.

3. Centipedes

Carnivorous and nocturnal, with their 100 feet, these pests can move quickly and spend most of the day hiding in humid, secluded places. They are highly attracted to the moist, humid parts of the home because they need to rehydrate constantly in order to live.

4. Earwigs

Known to burrow into topsoil outside, these nocturnal bugs can also infiltrate dark and humid areas of your home. You are most likely to find them around floor drains, bathrooms, or under rugs or furniture.

5. Roly-Poly Bugs

Also known as pill bugs, sow bugs, potato bugs, or armadillo bugs, these bugs often infest damp basements.
