Bats Near the Home

Bats live in both cities and wooded areas, eating half of their weight in insects every night. When looking for places to roost, they choose protected spots like sheds, attics, and smokestacks. At times, bats in chimneys cause problems due to their breeding habits and potential for disease.

Why Do Bats Roost in Chimneys?

These pests enter chimneys to hibernate and reproduce. Homeowners with a maternity colony of bats in the chimney may have a long-lasting problem on their hands. The animals have strong homing instincts and usually return to the same roosts. A bat can live for over six years, and females produce a pup every season.

Issues with Bats in Chimneys

When bats roost in chimneys, their droppings and urine build up on bricks and shingles. This leads to a musty odor and contaminated runoff during rainstorms. Bats in chimneys also create dark, oily stains similar to those left by rodents.

Any time bats live near humans, there is a definite risk of contracting rabies from a bite. Even a dead bat can spread the disease. In addition, airborne spores that develop within the pests' droppings may transmit histoplasmosis to humans.


To deter bats from roosting in the chimney, a variety of methods can be helpful:

  • Exclusion tubes - This device is a one-way exit, allowing bats in the chimney to leave but not to return.
  • Mesh screens - Placing wire mesh over a chimney keeps bats out, though it is important to avoid trapping any animals inside.
  • Chimney caps - Similar to a mesh screen, a cap stops pest wildlife from entering.
  • Bat boxes - Installing this alternative home encourages bats in chimneys to move out on their own.

Setting up some of these devices requires special knowledge and equipment. Accessing the chimney also means getting onto the roof, which can be dangerous for homeowners. For safe and effective wildlife management, call Critter Control when bats cause problems.

It has been very effective at reducing the number of mice, lizard, and snake sightings. During one visit Edgar removed a rattlesnake he came across. We may see a snake maybe two to three times during the spring and summer months, but it has been far less than before.

Full service. Excellent job of extracting raccoon, cleaning all animal waste, sanitizing, and spraying anti-parasitic substance. They closed all potential ports of entry, though the work did not match the vinyl, and it looks kind of tacky. They added blown insulation, which added a lot to the cost. They provide a one year warranty against animal intrusion, with an option to extend the warranty at the end of each one- year period. They were willing to work with me one the price. I will probably extend my warranty, and will definitely use them it the future.

I was really impressed by these guys. Got a call within a few hours of making an inquiry. Had a rep out to inspect the situation by the end of the week, and when they laid out the timeline they kept if not exceeded listed times.

Rob, Travis, and Jim were all professional, polite, and courteous and after months of hearing squirrels in my ceiling they are gone and the repair to my flashing looks excellent. Can't recommend these guys enough.

Critter Control did a great job of evaluating our house for sites of entry after we found bats and a squirrel in our attic. They completed their work promptly and professionally.

We heard some noise from the corner of our house. Concerned that it could be inside we called for an inspection. Jessy arrived as scheduled and conducted a complete inspection of our home. Based on a recording we made he determined we had a tree frog on our roof. I was pleased that we didn’t have any rodent in our house. And his inspection could a few spots I can tighten up around my house. I am very happy with the outcome.

We have a vacation home in Western Mass and haven’t been there much during the pandemic as we live and work in Atlanta, GA. On our most recent visit we noticed that we had some rodent intrusion as well as some un-welcomed wildlife who decided to make our vacation home their home.

We contacted Critter Control and Mr. Cahoon was quick to set up an appointment as we wouldn’t be in town very long. He came out and assessed our issues. He informed us of our options to both eradicate and control future intrusions. Keeping in mind that wildlife is wildlife! He quickly got to work eradicating the rodents and wildlife from our home and addressing the intrusion issues. We feel much better leaving our vacation home for periods at a time knowing that Mr. Cahoon and Critter Control did their job and did it right! Thanks again!

We bought an old cabin last spring , it was used for years as a summer vacation cabin, therefore maintenance wasn’t a priority. After our project to remodel started, we found evidence of mice droppings.

We immediately called Critter Control and they came and gave us a reasonable estimate to remove all remnants and insulation. They sanitized and replaced with new insulation and sealing up points of entry .

Seeing their professional work made us feel confident and secure that the problem was solved ! Everyone we worked with continued to show professional and respectful work. Highly recommend this company! We continue to use critter control monthly to be sure we are mice and bug free!
