Fleas

Fleas feed on the blood of mammals. Outdoors, fleas are found in moist, shaded spots near pet resting areas. Indoors, larvae are often found under furniture and in pet bedding. The female produces an average of 27 eggs per day, which hatch into larvae, feed on adult flea excrement, then spin cocoons in which they mature. Adult fleas may stay cocooned up to five months, but can emerge within seconds when stimulated by a passing animal.
