Rainy Days Bring Unwanted Guests: Why Pests Invade Indoors

When the rain doesn't stop pouring, it’s not just ants looking for shelter—many pests seek refuge indoors to escape the wet conditions. Insects and rodents that typically live in the ground, under debris, or in outdoor nests can find themselves displaced by heavy rainfall.
Here’s why rain brings pests inside:

Flooding Forces Them Out – Many pests, including ants, cockroaches, and spiders, live in underground burrows or hidden outdoor spaces that can become waterlogged. To survive, they head for dry, safe areas—like your home.

  • Increased Humidity – Damp environments attract pests such as termites, mosquitoes, and centipedes, which thrive in moisture-rich conditions.

  • Food Sources Get Washed Away – Rain can disrupt a pest’s usual food supply, driving them indoors in search of sustenance.

  • Easier Access Points – Storms can weaken structures, creating gaps and cracks that pests can squeeze through. Strong winds and heavy rain may also dislodge outdoor hiding spots, making homes more inviting.

To keep pests out, seal any cracks, eliminate excess moisture, and keep food well-stored. A little prevention can go a long way in keeping unwanted visitors at bay!

A Prolonged Problem

Normally, when the rain subsides, pests return to their natural habitats. Unfortunately, with four months of continuous heavy rain, the problem is only getting worse. The extended wet conditions have forced more pests indoors, creating a growing infestation issue that won’t go away on its own.  Right now with winter fast approaching and temperatures already dropping, these pests are likely to settle in for good, seeking warmth and shelter inside your home.
