Understanding Squirrel Behavior

Squirrels are active critters that are always on the lookout for a cozy and safe place to build their nests. Attics provide the perfect environment for squirrels to seek shelter, especially during the colder months. Understanding squirrel behavior can help you effectively prevent infestations in your home.

Squirrels are skilled climbers and jumpers, making it easy for them to access your attic through tree branches or power lines that are connected to your home. Once inside, squirrels will chew on wood, insulation, and electrical wiring, causing structural damage and potential fire hazards.

How do you know if squirrels have taken up residence in your attic? Look out for these telltale signs:

  • Scratching or scampering noises coming from your attic
  • Chewing or gnawing marks on wood, wires, or insulation
  • Droppings or urine stains in the attic
  • Nests made of leaves, twigs, and other debris

Preventing Squirrel Infestations

Now that you know the signs of a squirrel infestation, it’s time to take action to keep those furry intruders out of your attic. Here are some practical tips to prevent squirrel infestations:

Seal Entry Points

Inspect your home for any openings or gaps that squirrels could use to enter your attic. Seal off potential entry points with sturdy materials like steel mesh or hardware cloth to prevent squirrels from getting inside.

Trim Trees and Branches

Squirrels can easily access your attic by jumping from tree branches or power lines. Trim back any branches that are close to your home to make it more challenging for squirrels to reach your attic.

Install Squirrel Proofing

Consider installing squirrel-proofing measures, such as squirrel guards on vents and chimney caps, to prevent squirrels from gaining access to your attic through these entry points.

Remove Attractants

Do your best to eliminate any food sources or nesting materials that might attract squirrels to your property. Avoid feeding wildlife and keep your yard clean and tidy to make your home less appealing to squirrels.

Deterring Squirrels from Your Attic

In addition to preventing squirrel infestations, you can also deter squirrels from entering your attic by using natural and humane methods. Here are some tactics to deter squirrels effectively:

Use Repellents

Consider using natural squirrel repellents like peppermint oil, vinegar, or mothballs to deter squirrels from entering your attic. Place these repellents near potential entry points to create a barrier that squirrels will avoid.

Bright Lights and Loud Noises

Squirrels are sensitive to bright lights and loud noises, so consider installing motion-activated lights or using a radio to create a deterrent effect in your attic. This approach can help scare off squirrels and prevent them from nesting in your home.

Ultrasonic Devices

Ultrasonic devices emit high-frequency sound waves that are unpleasant to squirrels, making them an effective deterrent for keeping squirrels out of your attic. Place these devices near areas where squirrels are likely to enter your home for the best results.

If despite your best efforts, you find yourself dealing with a squirrel infestation in your attic, it’s essential to take swift action to remove the intruders safely. Here’s what you should do if you have a squirrel infestation:

Contact a Professional

Dealing with a squirrel infestation can be challenging, especially if you’re not familiar with wildlife removal. Contacting a professional wildlife removal service can help you safely and humanely remove squirrels from your attic.

Use Traps

Live traps can be an effective way to catch squirrels in your attic without harming them. Once you’ve trapped a squirrel, release it a safe distance away from your home to prevent it from returning.

Clean and Sanitize

After removing squirrels from your attic, it’s crucial to clean and sanitize the area to remove any droppings, urine, or debris left behind. This will help prevent the spread of disease and eliminate odors that might attract more squirrels in the future.
