When temperatures drop in Arizona, winter pests begin looking for a warm place to call home. Even though our winters are mild, the colder months still drive pests into your home in search of warmth, food, and water. If your home’s exterior has cracks, gaps, or other potential entry points, your living space becomes an open invitation for pests. 

To help you stay pest-free this season, here are the top three winter pests in Arizona and what you can do to prevent them from making your home theirs. 

1. Rodents (Mice & Rats)

During the winter months, rodents are some of the most common invaders. When it’s cold out, they’ll sneak through any crack or crevice to find warmth and easy access to food. 

Here are a few rodent infestation signs to watch for: 

Rodents aren’t just messy and destructive; they can also bring harmful bacteria into your home, making it crucial to keep these pests away from your home and family. Here’s how you can keep rodents out of your home:

2. Cockroaches

Roaches are year-round insects, but they become especially stubborn when temperatures fall. They search for moisture from leaky pipes, most often in kitchens where food is available. Some of the most common winter species include: American cockroaches and German cockroaches

These tiny bugs are resilient, but here are a few steps you can take to prevent them from coming inside: 

3. Spiders 

During Arizona’s winter, spiders—including black widows and brown recluse spiders—look for a quiet, warm, undisturbed place to hide. Spiders aren’t picky. They’ll hide in storage areas, garages, corners, and behind or in cardboard boxes. 

Here’s what you can do to prevent them:

How to Pest-Proof Your Home for Winter

Here are the best winter pest prevention methods recommended by your local pest control experts at EcoGuard:

1. Seal Exterior Cracks & Gaps

Check the entire exterior of the home, including the foundation, vents, and around the pipes. Small cracks are major entry points for winter invaders.

2. Install or Replace Weather Stripping

Proper weather stripping around doors and windows keeps bugs, insects, and cold air out.

3. Reduce Easy Access to Food

It’s easy to overlook simple pest attractants like food, but if you want a pest-free home this winter, it’s best to stay on top of your pantry and kitchen cleaning. Remember to wipe up crumbs, use airtight containers for food, and don’t leave pet food out overnight. 

4. Keep the House Clutter Free

Fewer hiding spots mean a lower chance of pest activity.

5. Trim Trees and Remove Debris

Overhanging trees, leaf piles, or messy yards increase easy access routes.

8. Schedule Professional Winter Pest Control

A seasonal winter pest control treatment can prevent pests, stop infestations early, and keep your home pest-free year-round.
