These small, wingless, blood-sucking pests create a lot of anxiety for man. Most varieties are around 1/16th inch in size (the Cat Flea can be considerably larger), and are brownish or black in color. They will feed on any warm-blooded animal, including mankind. Fleas prefer to live in fur or feathers, and their body features are well adapted to do so. Tiny claws hold on to the host, and flattened spins on the body help them move
Hundreds of eggs are deposited on objects located near a water source. In about a week, they hatch with the larvae going into the water to feed on organic materials. They pupate above the water level, becoming adults in a short period of time. Adults emerge from May-August. There can be two or more generations in a year.
