Early Detection

Although roof rats prefer warm, coastal climates, they thrive in many regions of the U.S. Because the pests are nocturnal and tend to nest overhead, infestations can be difficult to spot. To start effective control as soon as possible, keep an eye out for signs of roof rats in homes.

Identifying a Roof Rat Infestation

Signs of roof rats around the house include:

  • Droppings along baseboards
  • Noises coming from attics and walls just after dusk
  • Remnants of nests in attics, cabinets, and other areas above the ground
  • Smudges on surfaces from the pests' oily fur
  • Gnaw marks on wood trim, wires, and other household items.

Roof Rats or Norway Rats?

Roof rats and Norway rats are the two rat species most likely to enter homes. While the signs of roof rats and Norway rats are similar, there are a few differences that aid in exclusion and removal.

Roof rats leave behind the most evidence of their presence in elevated places, where they prefer to nest. On the other hand, Norway rats live at ground level or below. Extensive rat damage in basements or burrows around home foundations are likely not a sign of roof rats.

Problems & Concerns

Although roof rats aren't aggressive toward people, the pests create many health risks. In fact, some of the signs of roof rats in the house indicate possible dangers to residents as well.

Droppings in pantries suggest that the pests are feeding on stored goods. Food tainted with rodent waste can transmit salmonellosis and many other illnesses. In addition, roof rat nests may contain disease-causing parasites from the pests' fur, while chewed wires pose a fire hazard.

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!
