In Sammamish, the rainy season usually lasts from November through February. During these months, the weather is wet, damp, and humid. While the extra rain helps trees and plants grow, it also brings many pests closer to homes. When outdoor shelters flood and the ground becomes soaked, pests look for warm, dry places to hide and that is often inside your house. Many families rely on help from a Sammamish pest control company when these pests become too hard to manage on their own. Understanding which pests come inside during rainy months can help you get ahead of them and protect your home.
Why Rainy Weather Brings More Pests
Rainy weather creates the perfect conditions for pests to survive and multiply. Here are some reasons pests become a bigger problem when it rains:
High Humidity
Moisture builds up in crawl spaces, basements, and attics. Wood stays damp, which attracts ants and termites who love soft, wet wood and use it for nesting.
Heavy Rainfall
When soil gets soaked, pests such as rodents, spiders, and ants leave their outdoor nests and move indoors to stay safe and dry.
Standing Water
After storms, puddles form in yards, gutters, buckets, or outdoor toys. These places become perfect breeding spots for mosquitoes.
When all these conditions mix together, it creates a perfect storm for pest problems in Sammamish homes.
Common Rainy Season Pests in Sammamish
Ants
When rain floods their nests, ants rush indoors looking for dry ground and food. Carpenter ants can be a serious issue because they are drawn to wet or damaged wood, which can weaken parts of the home.
Rodents
Rats and mice move indoors quickly when their burrows fill with water. They can squeeze through tiny cracks and may hide in garages, attics, or kitchen spaces. Rodents spread germs and chew wires, which can cause electrical problems or fires.
Spiders
As pests move indoors, spiders follow them because they hunt other insects. They like dark corners, basements, and storage spaces. Although spiders help control bugs, most people don’t want them living inside.
Earwigs, Silverfish, and Centipedes
These pests love humid areas and will enter bathrooms, laundry rooms, and basements. Silverfish can damage books, clothing, paper, and stored items.
Mosquitoes
Mosquitoes lay eggs in standing water left after storms. Their population can grow fast, and they leave itchy bites that make being outdoors unpleasant.
Termites
Dampwood termites thrive in wet wood caused by leaks or constant moisture. They can live in basements, soggy wood near the ground, and wet structures, causing serious damage over time.
Cockroaches
Cockroaches love dark and wet hiding spots. Rain often forces them inside where they hide in kitchens, bathrooms, and behind appliances. Roaches can trigger allergies and asthma.
How to Reduce Rainy Season Pest Problems
Remove Standing Water
Dump water from buckets, birdbaths, plant trays, and toys after rain.
Seal Entry Points
Close gaps around doors, windows, pipes, and the foundation to keep pests out.
Fix Water Leaks
Repair roof, gutter, or plumbing leaks quickly so wood and walls don’t stay wet.
Store Food Safely
Keep food in sealed containers and wipe counters and floors daily.
Trim Plants and Brush
Keep bushes and tree branches cut back so pests can’t climb into the home.
Clean Gutters
Gutters full of leaves can hold water and attract mosquitoes and insects.
Use Fans and Dehumidifiers
Lowering indoor moisture makes your home less attractive to pests.
Stay Ahead of Rainy Season Pests
Rainy weather is part of life in Sammamish, but pests don’t have to be. By keeping your home dry, clean, and sealed, you can stop many pests before they become a bigger problem. Regular home inspections and quick repairs can help keep your family safe and comfortable all season long.
