Fleas in Tennessee | Pest ID Guide
Quick Facts About Fleas
Fleas are tiny, jumping insects that feed on the blood of pets and people. The cat flea is the one found on most Tennessee cats and dogs. The adults on your pet are only part of the problem; most of an infestation lives in your carpet, furniture, and yard as eggs, larvae, and pupae.- Size: About 1/12 to 1/8 inch
- Color: Reddish-brown to dark brown
- Shape: Flattened side to side, so they move easily through fur
- Movement: Can jump many times their body length
- Season: Peak in warm, humid months, but indoor infestations can continue year-round
- Hosts: Cats, dogs, and wildlife; they’ll bite people too
Signs of Fleas
- Pets scratching: Constant scratching, biting, or licking, especially at the base of the tail
- Flea dirt: Tiny black specks in pet fur or bedding that turn reddish when wet
- Bites on people: Small, itchy red bumps, often around the ankles and lower legs
- Jumping specks: Tiny dark insects hopping on carpet or furniture
The Flea Life Cycle
Understanding the life cycle explains why fleas are hard to get rid of.- Eggs: Adult females lay eggs on the pet, which fall off into carpet, bedding, and furniture.
- Larvae: Hatch and hide deep in carpet fibers and cracks, feeding on debris and flea dirt.
- Pupae: Spin cocoons that protect them from most treatments. They can wait weeks or months, then hatch when they sense vibration or warmth.
- Adults: Jump onto a host and begin feeding and laying eggs within days.
That’s why fleas can seem to appear out of nowhere when you move into a home or return from a trip, and why new fleas keep appearing for a few weeks after treatment.
Health Risks
Flea bites itch and can become infected from scratching. In pets, fleas can cause flea allergy dermatitis, spread tapeworms, and cause anemia in young or small animals. Heavy infestations are miserable for pets and people alike.
How to Get Rid of Fleas
- Treat every pet: Use a veterinarian-recommended flea product on all dogs and cats in the home, even those without obvious fleas.
- Vacuum daily: Vacuum carpets, rugs, furniture, and pet areas every day for a few weeks, and empty the vacuum outside. Vibration helps trigger pupae to hatch so treatments can reach them.
- Wash bedding: Wash pet bedding, throw blankets, and your bedding in hot water.
- Treat the home and yard: Professional treatment with growth regulators breaks the life cycle indoors and in shaded areas of the yard.
- Be patient: Expect some fleas for two to three weeks as pupae finish hatching.
How to Prevent Fleas
- Keep pets on year-round veterinarian-recommended flea prevention
- Vacuum regularly, especially where pets sleep
- Keep grass mowed and clear debris in shaded areas
- Discourage wildlife such as raccoons, opossums, and stray cats from denning around your home

Frequently Asked Questions
How do I know if I have fleas?
Look for pets scratching constantly, tiny black specks of flea dirt in fur, itchy bites around your ankles, and small jumping insects on carpet or furniture.
Why do I still have fleas after treating my pet?
Most of an infestation lives in the home as eggs, larvae, and pupae. Pupae resist treatment and keep hatching for weeks, so the home needs treating too.
Can fleas live in my house without pets?
Adults need a host, but pupae can wait for weeks or months, and wildlife can bring fleas into yards, crawl spaces, and attics.
Do fleas bite people?
Yes, usually around the ankles and lower legs, leaving small itchy red bumps.
How long does it take to get rid of fleas?
Usually a few weeks, since pupae keep hatching after treatment. Daily vacuuming helps.
