Squirrels might look cute frolicking in your yard, but their charm quickly fades when they invade your attic. If you’ve been hearing the scurry of little paws above your ceiling, it’s time to take action. Here’s how to deal with these unwelcome guests.

Understand the Intruders’ Habits

Before sealing your home against squirrels, it’s crucial to learn their routines. Do they leave during the day to forage? Are they active at night? Observing their schedule helps determine the safest time to act. If you’re unsure about your local squirrel species’ habits, contact your cooperative extension service for guidance.

Inspect Your Home’s Exterior

Squirrels can squeeze through holes as small as two inches, so grab a flashlight and head to your attic. Look for light peeking through cracks or gaps. If the attic isn’t accessible from inside, use binoculars to inspect your home’s exterior. Pay close attention to areas like siding, soffits, fascia, roof vents, and the foundation.

Prepare to Seal Entry Points

Once you’ve identified the squirrels’ entryways, wait until you’re certain they’re outside. Then, seal all holes except one. Use materials like stainless steel mesh, sheet metal, or aluminum flashing that squirrels can’t chew through. Caulk or foam sealant works well for smaller gaps and can be painted over for a seamless finish.

The Final Closure

When you’re sure all squirrels are out, seal the last remaining entry point. This prevents reentry and protects your home from future invasions.

What About Baby Squirrels?

Dealing with a mother squirrel and her babies requires extra care. If babies are present, sealing the entry could leave them trapped inside, causing the mother to frantically try to get back in. Worse, it may lead to the unfortunate death of the babies.

To check for a nest, wear gloves, a dust mask, and a headlamp. Search for nests within 20 feet of the entry point but keep your distance. If you suspect babies, allow them two months to mature and leave on their own, or hire a wildlife control professional to handle the situation humanely.

Humane Eviction Methods

If you’re eager to encourage squirrels to leave, consider these tactics:

• Sound and Light: Place a lamp with a cool-burning LED bulb and a radio tuned to a talk station in the attic. Squirrels dislike noise and bright lights, which may drive them away.
• Traps and One-Way Doors: For about $65, you can purchase a one-way door that allows squirrels to exit but not return. Alternatively, use a live trap to catch and release them at least three miles from your home.
• Predator Urine: Available at farm supply stores, predator urine can be an effective deterrent. Soak rags in it and place them near the squirrels’ entry or nest to simulate the presence of a predator.

What Not to Do

Some methods are ineffective or downright dangerous. Avoid setting smoke bombs in enclosed spaces, as this can cause fires. Pellet guns aren’t recommended either—misfires can lead to unintended injuries. And while squirrel pot pie might appeal to some, it’s not a viable solution for most homeowners.

Prevent Future Infestations

To keep squirrels at bay, ensure shrubs and trees are trimmed at least five feet from your house. This distance prevents most squirrels from leaping onto your roof. Regularly inspect your home for potential entry points and seal them promptly.

Squirrels may be tenacious, but with careful planning and humane methods, you can reclaim your attic and enjoy a squirrel-free home.
