Fleas in Bristol

Fleas are small, agile, usually dark-colored, wingless insects. They have tube-like mouth-parts adapted to feeding on the blood of their hosts. Their legs are long, the hind pair well adapted for jumping (vertically up to seven inches; horizontally thirteen inches – around 200 times their own body length, making the flea one of the best jumpers of all known animals (in comparison to body size).

Fleas are the most common ectoparasites found on cats and dogs, so they frequently turn up as household pests. Fleas are annoying to people and pets, especially during spring and early summer when their numbers tend to increase dramatically here in Tennessee.

Flea Habitat

Fleas thrive in many climates but prefer moist, humid and shady areas. The area underneath a porch or deck can turn into an overwintering site. Areas with tall grass, leaf litter, weeds, wood piles, gravelly areas, and sandy patches are all attractive to fleas. Even the tiniest crack in concrete can harbor fleas and they especially like shrubs, leaves, and trees, but do not fare well in sunny areas or open grass. Fleas usually enter structures attached to pets, and they can quickly find refuge in homes. Flea larvae do not like the light so carpets, bedding, pet beds, and upholstered furniture make cozy homes for fleas, flea eggs, and flea larvae.

Flea Behaviors & Dangers

Fleas feed mainly on non-human animals but may bite and infect humans. Bites from fleas look like small red dots and may occur in two or three groups or clusters around feet, ankles, and legs. Though they may trigger allergic reactions, flea bites will not often have a serious impact on a person’s health. However, some people and pets suffer from flea bite allergic dermatitis, characterized by intense itching, hair loss, reddening of the skin, and secondary infection. One flea bite can initiate an allergic reaction, and itching can persist for up to five days after the bite.
