Fleas

Home » Pest Library » Fleas

Fleas are common blood-sucking insects with flattened bodies and powerful legs, and their bites can cause significant discomfort for both pets and humans. These tiny insects are known for their ability to jump long distances and quickly infest homes, especially those with pets. Once they’ve established a foothold, they can be challenging to eliminate completely.

While fleas can transmit serious diseases like the bubonic plague, a more common concern is tapeworm, which pets may contract when accidentally swallowing a flea infected with tapeworm larvae.

Fleas are usually brought into homes by pets who come in contact with other infested animals outside. Once indoors, these pests lay eggs near your pet’s sleeping areas and feed off their blood.

Getting rid of fleas requires a multi-pronged approach. Pets can be treated with frequent baths with flea shampoo, combing, and using flea control products like collars and sprays. To address an infestation in your home, start by washing pet bedding, including blankets, cushions, and toys, in hot water (at least 140°F) to kill fleas, eggs, and larvae. Floors, carpets, furniture, and upholstery in affected areas should be vacuumed or steam cleaned.

For severe infestations, consult a pest control professional to safely and thoroughly treat areas with targeted flea control insecticides.
