When homeowners think about pest problems, they usually picture kitchens, bathrooms, or pantries. But in reality, one of the most common starting points for pest infestations is the garage.
In the Coachella Valley, garages offer everything pests are looking for: easy access, shelter from heat, clutter to hide in, and direct pathways into the rest of the home. Because garages are often treated as storage spaces rather than living areas, early pest activity frequently goes unnoticed until the problem spreads indoors.
Here’s why garages attract pests so easily — and how infestations move from the garage into your home.
Garages Are Full of Easy Entry Points
Garage doors are rarely sealed as tightly as front or back doors. Even a small gap beneath the door or along the sides can allow ants, cockroaches, spiders, and rodents to enter.
According to the Environmental Protection Agency, many common household pests can squeeze through openings as small as 1/16 of an inch.
Cracks in concrete slabs, gaps around utility lines, and worn weatherstripping all make garages one of the easiest access points for pests.
Clutter Creates Perfect Hiding Places
Garages often contain cardboard boxes, seasonal decorations, unused furniture, and stored supplies. Unfortunately, these items provide ideal hiding and nesting spaces for pests.
Cardboard is especially attractive. It absorbs moisture, provides insulation, and is easy for insects and rodents to chew or burrow into. The University of California Integrated Pest Management program notes that cluttered storage areas significantly increase pest activity.
Once pests establish themselves in stored items, they can remain hidden for weeks or months.
Garages Offer Direct Access to the Home
From the garage, pests don’t have far to go. Shared walls, interior doors, plumbing lines, and attic access points allow insects and rodents to move deeper into the home.
Ants follow plumbing lines into kitchens. Cockroaches slip through wall voids toward moisture. Rodents travel through insulation and ceiling spaces, often reaching living areas without being seen.
Warmth and Moisture Attract Pests Year-Round
In the desert, garages stay warmer than outdoor spaces and often contain moisture sources like water heaters, washing machines, irrigation controls, or condensation from air conditioning lines.
These conditions attract pests that depend on water and shelter to survive. Cockroaches, in particular, thrive in warm, humid pockets within garages.
Rodents Commonly Enter Through Garages
Rodents frequently use garages as their first entry point. According to the USDA, mice and rats only need an opening the size of a quarter to enter a structure.
Once inside, they nest in stored items, insulation, or wall voids, often remaining unnoticed until damage or droppings appear.
How to Reduce Pest Activity in Your Garage
A few preventative steps can significantly reduce the risk of infestations starting in the garage:
- Seal gaps under garage doors with proper door sweeps
• Replace worn weatherstripping
• Store items in sealed plastic containers instead of cardboard
• Keep boxes elevated off the floor
• Reduce clutter and unused storage
• Inspect stored items before bringing them indoors
• Seal cracks in concrete and around utility lines
Garages that are clean, sealed, and organized are far less attractive to pests.
Frequently Asked Questions
Q: Can pests really start in the garage and spread indoors?
A: Yes. Garages often serve as the first entry point before pests move into kitchens, walls, and living spaces.
Q: Is cardboard storage really a problem?
A: Yes. Cardboard provides shelter and absorbs moisture, making it ideal for insects and rodents.
Q: How often should garages be inspected for pests?
A: At least once or twice a year, or anytime you notice droppings, insects, or unusual odors.
Q: Will sealing the garage help reduce indoor pest issues?
A: Absolutely. Sealing garage entry points is one of the most effective prevention steps.
Stop Pest Problems Before They Move Inside
Many infestations begin quietly in garages long before homeowners notice activity indoors. Addressing garage vulnerabilities early helps protect the rest of your home from costly, disruptive pest problems.
