Why Are There So Many Bugs in My House After It Rains?

Bugs are never welcomed guests in your house. You find them crawling on your ceilings, walls, and sometimes even on your arms or legs—it’s enough to make anyone call an exterminator right away. While you’ll find critters in your home throughout the whole year, you may have noticed you find more bugs in your home after it rains. At Delta Pest, we hear this remark a lot because it’s true. It's very common to see more bugs around the home after heavy rain as insects want shelter from the rain, just like we do. While staying out of the rain is a big reason for pests to wander inside, different kinds of insects may enter your home after a rainstorm for various reasons.

Common Bugs To See After It Rains

While may critters come out after the rain, here are some of the critters you are most likely to see in your home after it rains:


Cockroaches worm their way into your home after a rainstorm to stay dry. Since they mostly live in drains, sewers, and pipes, when it rains, those pipes and drains flood, making it an unsafe place to stay. They’ll crawl out of your drains or through cracks in your home and camp out to survive until the rain subsides. You can usually find them anywhere pipes are found including bathrooms, kitchens, and laundry rooms.


Sowbugs, also known as, pillbugs, roly-polys, potato bugs, and woodlice may show up in your home after it rains. While these creatures are harmless, they are still a nuisance to homeowners everywhere. Sowbugs actually need moisture to survive and will generally live in damp soil, however, when too much rain threatens their lives, they’ll seek shelter in your home. Thanks to the increased moisture in the air after rain, sowbugs can survive indoors. You’ll often find them near windows and doors leading to the outside.


Living in mounds throughout your yard, ants are at high risk for flooding. When rain pelts down relentlessly, ants will seek out the closest dry land, which usually ends up being your home. Since food is usually their top priority, you’ll most likely find ants in your kitchen after a storm.


Spiders love warm weather, and when a rainstorm hits, temperatures usually drop. Spiders will seek warmer places to wait out the rain, like your house. In addition to wanting to stay warm and dry, spiders will also wander into homes after a rainstorm to find prey. With the increase in insects in your home due to the weather, spiders will roam about looking for other bugs to eat.


Centipedes scare many people on a regular basis because of their particularly creepy appearance. These many-legged creatures need moisture to survive and actually like the rain in moderate amounts. You’ll find centipedes in your home after a rain, however, because they are searching for other bugs to eat that have also invaded your home. They can be found anywhere other insects are lurking or in areas that generally have high moisture such as the bathroom, kitchen, laundry room, or attic.
