Habits

Fleas can live for about 100 days during which time the females produce 400-500 offspring. Fleas transport themselves on rodents and other mammals, and usually remain on their hosts at all times. These pests use their powerful legs to jump as high as 8" vertically, which is 150 times their own height. If humans could do this, we would be able to leap over skyscrapers.

Habitat

Fleas infest both household pets and wild animals like opossums, raccoons and skunks. They can also be found on shoes, pant legs or blankets, which can transfer the fleas to new environments.

Threats

Fleas are the most common transmitter of the rare bubonic plague. They also transmit the bacterial disease murine typhus to humans through infected rats. Their saliva can cause serious flea allergy dermatitis in pets and their debris has been reported to cause similar allergic reactions in humans. Fleas can also transfer tapeworms and cause anemia in pets, which is why active flea management is an important component of pet care. Flea bites commonly cause painful, itchy red bumps.
