Protect your home from unwanted guests during wet weather.

When heavy rain hits Austin, TX, it doesn’t just green up your lawn — it also drives pests to seek shelter inside your home. Insects and rodents that normally live outdoors are suddenly flooded out of their hiding spots, making your warm, dry home an ideal refuge.

At TOPS Pest Control, we see a major uptick in pest activity after storms and extended periods of rain. Here’s why it happens — and what you can do to protect your home.

🌧 Why Do Pests Invade After Rain?

1. Flooded Nests and BurrowsRainwater fills the underground homes of ants, roaches, and spiders, forcing them to flee. Many of them make their way through tiny cracks, weep holes, and gaps around doors and windows to escape rising water levels.

2. Moisture Attracts InsectsMany pests are drawn to the moisture left behind by rainfall. Damp crawl spaces, leaky basements, and wet walls become breeding grounds for silverfish, centipedes, earwigs, and more.

3. Food Becomes Scarce OutdoorsFlooded conditions often disrupt food sources outside, so pests like rodents, roaches, and ants enter homes in search of crumbs, pet food, and garbage.

4. Shelter from the StormJust like us, pests want to stay dry. Homes offer stable temperatures and protection from predators and harsh weather, making them an attractive option for invading pests.

🛑 Common Pests That Invade After Rain

Cockroaches – Including American and German roaches
