A raccoon family establishes a latrine and tears insulation and wires all in the first night. Act the moment you hear them.
Schedule ConsultationA 30-lb raccoon on your roof damages shingles and pulls back flashing to force its way into your attic in minutes.
Schedule ConsultationRaccoon feces carry leptospirosis and roundworm. Attic cleanup requires PPE and professional biohazard protocols — never DIY.
Schedule ConsultationA pregnant female choosing your attic as her den gives birth to 4–7 kits — and they'll all grow up there if not removed promptly.
Schedule ConsultationMothballs, coyote urine, and bright lights do nothing on habituated Bay Area raccoons. Physical exclusion is the only solution that works.
Schedule ConsultationActive wildlife in your structure is an emergency. ATCO offers same-day response for attic invasions — humane, legal, and permanent.
Schedule ConsultationOverturned trash cans, torn soffit or roof vents, large droppings on your roof or deck, and scratching sounds in the attic at night are all common signs. Raccoons also leave muddy paw prints near entry points and on downspouts.
Unsecured garbage, pet food left outdoors, fallen fruit, bird feeders, and open compost bins are top attractants. Raccoons also seek warm attic spaces for denning, especially in spring when raising their young.
Raccoons are a primary rabies carrier and their droppings contain Baylisascaris roundworm, which causes serious neurological illness in humans. They tear up insulation, chew wiring creating fire hazards, and cause thousands of dollars in attic and roof damage.
Attics are the most common nesting site—raccoons enter through damaged soffits, roof vents, and gaps where the roof meets the fascia. They also den in chimneys, crawl spaces, under decks, and in garages with open access.
Raccoon break-ins peak in late winter and early spring when females seek warm, protected spaces to give birth. Babies are born in March through May, and a mother with kits in your attic won't leave until they're mobile—typically 8 to 10 weeks.
If you hear sounds in your attic, find torn roofing or vent damage, or see raccoons on your property regularly, call a professional immediately. DIY trapping is illegal in many areas, and sealing entry points without checking for babies inside can create a destructive emergency.
Use heavy-duty cans with locking lids or bungee cords. Raccoons easily flip standard lids.
Never leave pet food or water bowls outside overnight — it's one of the top raccoon attractants.
Motion-activated lights and sprinklers startle raccoons and discourage return visits.
Cut branches within 10 feet of your roof. Raccoons use them as highways to your attic.
Cover attic vents with heavy-gauge galvanized steel mesh. Raccoons tear through lightweight screening easily.
Pick up fallen fruit, secure compost bins, and clean up birdseed spills. Consistent food trains raccoons to visit nightly.
Raccoons can be aggressive when cornered, especially mothers with babies. They carry rabies and roundworm.
Poisoning raccoons is illegal in California and creates serious risks for pets, children, and other wildlife.

Even unintentionally — bird feeders, fallen fruit, and compost piles attract raccoons and teach them your home is a food source.
