Summer in Illinois brings longer days, warmer temperatures, backyard barbecues, and unfortunately, an increase in unwanted pests. While most homeowners focus on keeping bugs and rodents out of their living spaces, many overlook one of the biggest entry points to their home: the garage.

Your garage door is designed to protect your home, vehicles, and belongings. But when weather seals wear out, gaps develop, or damage goes unnoticed, your garage can become an open invitation for mice, insects, spiders, and other unwelcome guests.

If you’ve noticed more pests around your garage this summer, your garage door could be part of the problem.

Why Pests Love Garages

Garages offer everything pests are looking for:

• Shelter from extreme weather
• Dark, quiet hiding places
• Access to food and water
• Easy entry into your home

Many Illinois homeowners store pet food, bird seed, grass seed, recycling, and household items in their garages. These items can attract rodents and insects, especially during the summer months.

Once pests gain access to your garage, it becomes much easier for them to find their way into your home.

Common Summer Pests Found in Illinois Garages

1. Mice and Rodents

Mice can squeeze through openings as small as a dime. Even a tiny gap under your garage door can provide enough room for entry.

Signs of rodent activity include:

• Droppings
• Chewed cardboard boxes
• Damaged insulation
• Nesting materials

Rodents can also chew wiring, creating potential safety hazards and costly repairs.

2. Ants

Ants often enter garages searching for food and moisture. Cracks, damaged weather seals, and gaps around garage doors provide easy access.

Once ants establish a trail into your garage, they can quickly spread into the rest of your home.

3. Spiders

Garages are ideal environments for spiders because they provide shelter and a steady food source. While most spiders are harmless, many homeowners prefer not to share their garage with them.

4. Wasps and Hornets

Damaged seals, gaps around door frames, and small openings can allow stinging insects to build nests near or inside your garage.

5. Crickets, Beetles, and Other Crawling Insects

Warm summer evenings often drive insects toward garages, especially those with gaps that allow light and cool air to escape.

How Your Garage Door May Be Letting Pests In

1. Worn Bottom Seals

The bottom seal is one of the most important barriers against pests.

Over time, exposure to Illinois weather can cause seals to crack, flatten, or pull away from the door. When this happens, small gaps develop along the floor that allow insects and rodents to enter.

2. Damaged Weather Stripping

Weather stripping runs along the sides and top of your garage door.

If it becomes brittle, torn, or detached, pests can easily find their way inside through these openings.

3. Uneven Garage Doors

If your garage door no longer closes evenly, gaps may form at the corners or along one side of the opening.

These spaces can become easy access points for pests seeking shelter.

4. Damaged Door Panels

Cracked, dented, or deteriorating door panels can compromise the integrity of your garage door and create additional entry points.

5. Misaligned Tracks or Hardware

When garage door components become worn or misaligned, the door may not seal properly against the opening, leaving gaps that pests can exploit.

Simple Ways to Pest-Proof Your Garage

1. Inspect Your Garage Door Regularly

Walk around your garage and look for:

• Light coming in around the edges
• Cracked weather seals
• Damaged panels
• Visible gaps near the floor

Even small openings can become major entry points.

2. Replace Worn Weather Seals

New weather stripping and bottom seals can dramatically improve your garage’s defense against pests while also improving energy efficiency.

3. Keep the Area Clean

Reduce potential food sources by:

• Storing pet food in sealed containers
• Keeping recycling bins clean
• Removing clutter
• Sweeping regularly

4. Schedule Preventive Maintenance

A professional garage door inspection can identify issues before they become bigger problems.

Routine maintenance helps ensure your door closes properly, seals tightly, and continues protecting your home year-round.
