Squirrels in Ventilation

The ventilation system is essential for your home. The ventilation on your roof cycles fresh air to protect your home from heat and humidity. Plumbing vents introduce air to protect your plumbing and remove foul sewer gas. The intake for HVAC units introduces fresh air to your home. 

During home construction, these vents are rarely built with materials that can stop a squirrel. Squirrels can easily gnaw through a variety of home materials. Vents are attractive locations for squirrels to gain entry to your home. Once inside, squirrels can create nests, gain access to your attic or wall voids, and cause additional damage. 

How Do Squirrels Get In Vents? 

If a vent is uncovered, squirrels can easily access public or living areas. Squirrels can gnaw through most vent covers. Plastic, wood, and metals like aluminum are not strong enough to prevent a squirrel from getting into your vents. While searching for places to nest, squirrels often move through dryer vents that lead to attics or basements.

Damage Caused by Squirrels in Vents 

Squirrels in vents can cause a few problems for property owners.  

  • Squirrels are notoriously noisy as they travel through ductwork. Their scratching noises can be a consistent annoyance in a home or business. 

  • Squirrels often die in vents, spreading a foul odor throughout your property as they decompose.  

  • Squirrels in vents are a major fire hazard, as their nesting materials are extremely flammable. 

Squirrel Removal from Vents

professional wall vent installationVents are one of the most common entry points for squirrels. But soffits, eaves, and gaps in the fascia boards are some of the other most common entry points. A squirrel infestation is a sign your home is attractive to squirrels. Homeowners should avoid the use of squirrel repellents. At best, it is a temporary animal control solution. Homeowners need to solve the underlying issues for long-lasting squirrel control. That includes covering your vents and sealing other potential entry points.

A professional wildlife removal company can get squirrels out of vents and protect your home from future squirrel infestations. One-way doors are incredibly effective in getting rid of squirrels from vents.

BAT POOP CLEAN-UP AND PREVENTION! Bat guano removed from gables. No bats found in attic, so put new screens on all gable vents, as one screen was close to breaking and then bats may have gotten in! Great work in Tulsa!

Squirrels and chipmunks were in our attic. So we called Critter Control to do an inspection. Their representative climbed all over our very steep roof and found several places where squirrels had entered our attic.

Upon inspection of the attic, evidence of bats was also found. The Critter Control team came on time to completely caulk the entire perimeter of the house and create an exit strategy for the squirrels and bats.

Because bat droppings can cause histoplasmosis, this also required total removal and replacement of our attic insulation and sanitizing the space. Not a small job in a 1,300 sq. ft. attic! While Critter Control’s cost was high, our homeowners insurance covered most of it. Everyone representing Critter Control was professional, courteous and timely. I would highly recommend them to anyone who thinks they might have unwelcome guests living in their attic

On recommendations from a nearby pest control company, I called Critter Control for suspicious bat droppings.

Madison came out the same day to do an inspection. She was knowledgeable, thorough, and highly professional. She examined the ‘matter’ that had been scattered on my threshold and thought it was foliage. But she then asked to go up to my attic space where the bats could be roosting. She had to walk up 3 flights of stairs with a heavy ladder. She again spent some time searching all the nooks and crannies and found nothing.

She seemed so interested in her craft, it was truly inspiring to see! She reassured me and is writing up a prevention strategy for my appraisal. She charged me NOTHING!! I am so impressed. We need more Madisons in this world!

We noticed droppings on our brand new deck - we were given their number from our contractor. They came the next day. Brian looked at it and said - yeah, bats!! He then checked every area in our attic and he explained exactly what needed to be done.

He found evidence of a mice infestation, provided a referral and they are helping us as well. Great service, very informative, very professional! We are very satisfied and would recommend them to anyone who has any issues with any critters!
