Diseases Raccoons Carry: What Louisville Families Should Know
Raccoons are a leading wildlife disease vector in Kentucky. Here are the real health risks to your family and pets — and the practical steps that keep everyone safe.
The 6 Health Risks That Matter Most
Rabies
Transmitted through bites and scratches. Raccoons are one of the primary rabies vector species in Kentucky.
A rabid raccoon may appear disoriented, stagger, act unusually aggressive or unusually tame, or be active in broad daylight while looking sick. Rabies is virtually always fatal once symptoms appear, in both humans and unvaccinated pets — any bite or scratch requires immediate medical attention.
Raccoon Roundworm (Baylisascaris procyonis)
Transmitted by accidentally ingesting microscopic eggs from raccoon droppings — the biggest hidden danger of attic latrines.
Raccoons shed millions of roundworm eggs in their droppings, and the eggs survive for years in dry attic conditions. Infection in humans (especially children) can cause severe neurological damage. This is why the CDC recommends professional remediation of indoor raccoon latrines rather than DIY cleanup.
Leptospirosis
A bacterial infection spread through raccoon urine, contaminating soil, water, and attic insulation.
Humans and dogs can contract leptospirosis through skin contact with contaminated urine or water. Symptoms range from flu-like illness to kidney and liver damage. Urine-soaked attic insulation is a genuine exposure route during unprotected cleanup.
Salmonella & E. coli
Bacterial contamination from droppings on surfaces, in garden beds, and around trash areas.
Raccoon droppings can carry salmonella and E. coli that transfer to hands, tools, and surfaces. Wash thoroughly after any contact with areas raccoons frequent, and keep sandboxes covered — they are a favorite latrine site.
Canine Distemper
Not a human threat, but frequently fatal to unvaccinated dogs.
Distemper is common in Louisville's raccoon population and is a leading cause of "drunk-acting" raccoons seen during the day. Keep your dog's vaccinations current, and never let pets investigate a sick-acting raccoon.
Parasites: Fleas, Ticks & Lice
Raccoons denning in your attic bring their parasites with them.
When raccoons are removed, the fleas and ticks they leave behind look for new hosts — often your pets. This is one more reason full-service decontamination matters after removal.
How to Protect Your Family and Pets
Found a Raccoon Latrine in Your Attic?
Don't sweep, vacuum, or disturb it — that can aerosolize roundworm eggs. Professional remediation with PPE, HEPA filtration, and antimicrobial treatment is the safe path. Learn about our raccoon cleanup & decontamination service, which is often covered by homeowners insurance when paired with damage repair.
