Fleas are parasites that feed on the blood of any warm-blooded
body. The most common species is the cat flea, which often feasts
on cats, dogs and humans.
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.
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.
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.
