Fleas are tiny, flightless insects. They are 1.5 to 3.3 millimeters in length and have a tube-like mouth for feeding on blood. Their hind legs are adapted for jumping, and their wings are missing. They can jump more than seven centimeters vertically and thirteen inches horizontally. Their size is a factor to consider if you’re dealing with an infestation.
Fleas are small and easy to miss if you have poor vision. If your pet has white fur, you’ll be able to see fleas much easier. They are about 2.5mm long, and are brown to reddish-brown. Fleas have six legs, including a pair of hind legs larger than their forelegs. This allows them to jump eight inches. If they’re infesting your home, you should get rid of the fleas as soon as possible.
When fleas emerge from their cocoon, they search for their first blood meal. They only live on their host, which means they need fresh blood to grow and breed. Adult fleas can grow up to three millimeters in length. They’re about half the size of ticks. Female fleas are twice as large as males and have a wider, heavier abdomen. Fleas undergo a complete metamorphosis before they become adults. Once the adult flea emerges from its cocoon, it starts feeding and laying eggs.
Fleas are small insects that live on animals. Their larvae are about a quarter of an inch long and white. Their lifespan is between five and twenty days. The adult fleas cannot get bigger than this, so the majority of the flea population in a house is the larvae.
