Finding Opossums in Attics

Opossums are skilled climbers. The pests easily scale overhanging tree branches or power lines and gain access to rooftops. From there, they exploit weaknesses to gain entry in to attics.

Damage and Problems

Residents should be wary of having an opossum in the attic for many reasons. First, the pests' menacing, rat-like appearance makes for a frightening surprise when they are discovered. The pests also reproduce quickly. Females can carry two litters per year and give birth to about nine young at a time.

Opossums in attic spaces also keep residents awake by creating loud scratching sounds at night. They chew away at insulation and can create fire hazards by gnawing through electrical wires. In addition, opossums can introduce ticks, lice, and fleas into the attic and the rest of the house.

Furthermore, opossums are vectors for the following parasites:

  • Mites - These microscopic pests burrow under the skin, causing itchy rashes.
  • Roundworms - Larvae travel through the nervous system, liver, and lungs, causing fever or the enlarging of internal organs.
  • Flukes - These pests live in the abdominal cavity and intestinal walls, where they reach maturity and lay eggs.
  • Tapeworms - Common issues caused by tapeworms include digestive problems and abdominal pain, while more serious cases result in seizures or muscle damage.

Opossums in the attic may also carry fungal, bacterial, or viral diseases like leptospirosis and coccidiosis.


To drive away opossums in the attic, eliminate all food sources. Secure garbage can lids tightly, and tie down trash bins to prevent them from being tipped over. Water and food dishes intended for pets must be brought indoors nightly, and bird feeders should be installed on tall metal poles.

When dealing with problematic opossums, call the experts at Critter Control for fast and effective removal.

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!
