Why Do Squirrels Invade Attics?

Houston’s mild climate and urban greenery make attics a prime location for squirrels to nest. They seek warmth, protection from predators, and easy access to food.

Key Statistics:

• Year-Round Breeding: Unlike in colder regions, squirrels in Houston don’t hibernate. The warmer climate means that squirrels breed year-round, doubling their birthing season and multiplying their numbers at an alarming rate.

• Structural Damage Costs: In Williamson County, Texas, squirrels caused extensive damage to the Justice Center’s chillers, leading to replacement costs of $400,000, with additional monthly expenses of $13,600 for temporary solutions.

How Do I Get Rid of Unwanted Squirrels?

Removing squirrels requires a strategic and humane approach. Here’s what you should do:

1. Inspect Your Home for Entry Points

• Common access areas include rooflines, chimneys, soffits, and attic vents.

• Seal openings with durable materials like steel mesh or metal flashing.

2. Install One-Way Exclusion Funnels

• Exclusion funnels allow squirrels to exit the attic but block their return.

• Humane Tip: Ensure all squirrels, including babies, have vacated before sealing entry points to avoid trapping and harming them.

3. Use Live Traps

• Place humane traps near nesting areas or travel paths, baited with peanut butter or seeds.

• Legal Note: In Texas, trapped squirrels must be released within 10 miles of the capture site with the property owner’s permission.

4. Clean and Sanitize the Attic

• Remove nesting materials and disinfect droppings and urine to eliminate odors that could attract other squirrels or pests.
