Wildlife sightings are part of the charm of living in Southern Maine—but when critters decide to move in, they can cause serious problems for homeowners and business owners alike. From raccoons in the attic to squirrels in the walls, early detection is key to minimizing damage and restoring your peace of mind.
At Critter Control of Southern Maine, we specialize in humane and effective wildlife removal. Here are the top signs of a wildlife infestation and how you can catch the trouble early.
Unusual Noises
Scratching, scurrying, thumping, or chirping noises—especially at night—are often the first signs of wildlife in your home. Common culprits include:
Squirrels: Active during the day, especially in the morning and evening.
Raccoons: Nocturnal and often noisy.
Rodents: Gnawing and scratching sounds in walls or ceilings.
If you hear these sounds, especially in your attic, basement, or walls, it’s time to investigate.
Droppings and Urine Stains
Animal droppings are a sure sign that wildlife has made itself at home. Different species leave different types of waste:
Mice and rats: Small, pellet-like droppings.
Raccoons: Larger droppings, often found in specific areas called “latrines.”
Bats: Guano (bat droppings) typically found near entry points or in attics.
Aside from being unsanitary, these droppings can pose serious health risks, so don’t handle them directly.
Damaged Entry Points
Wild animals don’t knock—they break in. Check for:
-
Chewed holes in siding or under eaves
-
Torn or missing roof shingles
-
Gnawed vents or screens
-
Gaps around windows, chimneys, or utility lines
Mice can squeeze through a hole the size of a dime, and squirrels can chew through wood to gain access.
Nests or Nesting Materials
You may discover shredded insulation, leaves, paper, or fabric—all signs that an animal is nesting nearby. Attics, crawlspaces, and wall cavities are common nesting spots.
Tracks or Grease Marks
Look for paw prints, especially in dusty areas or snow-covered paths. Rodents and raccoons often leave greasy smudges or rub marks along walls where their fur brushes consistently.
Foul Odors
Dead animals, droppings, and urine can create powerful odors that linger. If you smell something musty, rotting, or pungent and can’t identify the source, it could point to a wildlife issue.
Pet Behavior Changes
Pets often notice wildlife before humans do. If your dog is barking at walls or your cat is staring intently at the ceiling, they may be reacting to movement or smells you haven’t noticed yet.
What To Do If You Suspect an Infestation
If you notice any of these warning signs, it’s important to act quickly. Wildlife infestations can escalate fast, leading to serious consequences like structural damage, fire hazards from chewed electrical wiring, contamination of insulation or ductwork, and health risks from parasites and diseases carried by animals. The best course of action is to contact a professional. At Critter Control of Southern Maine, we provide thorough inspections and safe, humane removal of unwanted wildlife. Our team also offers exclusion services to seal entry points and help prevent future invasions. Don’t wait for the problem to grow—reach out as soon as you suspect animal activity in or around your home.
