Common Bugs That Show Up When the Weather Cools Down

When the temperatures start to drop, most people think pests disappear until spring. The truth? Many bugs (and even rodents) are just looking for a warm, safe place to hide—often inside your home or around your yard.
At TruPest Solutions, we help Rialto and Fontana homeowners stay protected year-round. Here’s a look at the most common pests we see in the cooler months, where they like to hide, what they feed on, and why you don’t want them hanging around.
🕷 Spiders
Cooler weather drives spiders indoors in search of warmth and food.
Hiding spots: Garages, attics, basements, and quiet corners.
What they eat: Other insects—if bugs are inside, spiders won’t be far behind.
Why you don’t want them: Black widows and brown widows are venomous, and even harmless spiders leave messy webs.
🐜 Ants
Ants don’t take the winter off. Their super colonies simply move closer to food and water.
Hiding spots: Wall voids, foundations, and under landscaping.
What they eat: Crumbs, sugars, grease, and pet food.
Why you don’t want them: Once ants get established indoors, they spread quickly and can be tough to eliminate without professional treatment.
🪳 Cockroaches
Cold weather pushes cockroaches into warm, damp spaces where they thrive.
Hiding spots: Kitchens, bathrooms, laundry rooms, and around plumbing.
What they eat: Just about anything—crumbs, grease, and even cardboard.
Why you don’t want them: Roaches spread bacteria, contaminate food, and can trigger allergies and asthma.
🐭 Mice & Rats
Rodents aren’t technically “bugs,” but they’re one of the biggest winter invaders.
Hiding spots: Attics, garages, sheds, and inside insulation.
What they eat: Grains, cereal, pet food, and whatever they can chew through.
Why you don’t want them: They spread disease, chew wires, and cause costly property damage.
🦗 Earwigs & Crickets
These pests sneak inside to escape the cold.
Hiding spots: Basements, crawlspaces, and mulch beds near the foundation.
What they eat: Plants, fungi, and sometimes smaller insects.
Why you don’t want them: While not dangerous, infestations grow fast and make your home feel anything but comfortable.
