Fleas – Get to Know Them


It’s no circus when fleas are doing tricks on your couch…


Flea ImageFleas are small (1/16 to 1/8-inch long), agile, usually dark colored wingless insects with tube-like mouth-parts adapted to feeding on the blood of their hosts. Their legs are long, the hind pair well adapted for jumping (vertically up to seven inches; horizontally thirteen inches – around 200 times their own body length, making the flea one of the best jumpers of all known animals (in comparison to body size). Their bodies are laterally compressed, permitting easy movement through the hairs or feathers on the host’s body (or in the case of humans, under clothing). The flea body is hard, polished, and covered with many hairs and short spines directed backward, which also assist its movements on the host. The tough body is able to withstand great pressure, likely an adaptation to survive attempts to eliminate them by such as mashing and scratching. Even hard squeezing between the fingers is normally insufficient to kill a flea. It is possible to eliminate them by pressing individual fleas with adhesive tape or softened beeswax or by rolling a flea briskly between the fingers to disable it then crushing it between the fingernails. Fleas also can be drowned in water and may not survive direct contact with anti-flea pesticides.

Fleas lay tiny white oval shaped eggs better viewed through a loupe. The larva is small, pale, has bristles covering its worm-like body, lacks eyes, and has mouthparts adapted to chewing. The adult flea’s diet consists solely of fresh blood. In the pupal phase the larva is enclosed in a silken, debris-covered cocoon.

Life cycle and habitat

The flea life cycle begins when the female lays after feeding. Adult fleas must feed on blood before they can become capable of reproduction. Eggs are laid in batches of up to 20 or so, usually on the host itself, which easily roll onto the ground. As such, areas where the host rests and sleeps become one of the primary habitats of eggs and developing fleas. The eggs take around two days to two weeks to hatch.

Flea larvae emerge from the eggs to feed on any available organic material such as dead insects, feces, and vegetable matter. They are blind and avoid sunlight, keeping to dark places like sand, cracks and crevices, and bedding. Given an adequate supply of food, larvae should pupate and weave a silken cocoon within 1-2 weeks after 3 larval stages. After another week or two, the adult flea is fully developed and ready to emerge from the cocoon. They may however remain resting during this period until they receive a signal that a host is near – vibrations (including sound), heat, and carbon dioxide are all stimuli indicating the probable presence of a host. Fleas are known to overwinter in the larval or pupal stages.

Once the flea reaches adulthood its primary goal is to find blood – adult fleas must feed on blood in order to reproduce. Adult fleas only have around a week to find food once they emerge, though they can survive two months to a year between meals. A flea population is unevenly distributed, with 50 percent eggs, 35 percent larvae, 10 percent pupae, and 5 percent adults. Their total life cycle can take as little as two weeks, but may be lengthened to many months if conditions are favorable. Female fleas can lay 500 or more eggs over their life, allowing for phenomenal growth rates.

Habits:

  • Flea problems generally occur when a dog or a cat becomes infested and brings the fleas into the home.Most wild animals carry fleas, and occasionally, infestations will occur when a wild animal like a raccoon or squirrel lives in an attic, crawlspace or under the deck.
  • Adult fleas spend most of their time on the pet (dog or cat).
  • The adult must feed on blood to produce eggs, laying about 450 during their lifetime.
  • Their eggs fall off the pet and onto the pet bedding, couch or carpeting.
  • These eggs develop into maggot-like larvae which feed on the dried blood of the pets at the base of the carpet fibers.
  • The length of the chemical-resistant pupae stage is variable ranging from 1 day to 1 year depending on pressure,carbon dioxide, and warmth.

Home Preparation:

  • The pet should be treated by a veterinarian in conjunction with the home, preferably on the same day.
    • Advantage and Frontline are the most effective treatments which will
      control adult fleas for 1-3 months.
  • Remove all stored items from floors, under beds, and closets to make treatment accessible. Comforters and sheets should be washed and dried (high heat).
  • Steam clean infant (under 2 years old) rooms and vacuum daily. Pesticide will not be applied here.
  • Remove pet food, water dishes; cover and disconnect fish tanks; remove other pets.
  • Wash, dry-clean, or destroy all pet bedding.
  • VACUUM DAILY- Vacuuming before and up to 10 days after treatment removes eggs, larvae, and stimulates adults to leave their chemical resistant cocoons. Seal and discard of the vacuum bag outside.
  • People and pets should be out of the house for 4 hours after treatment.
  • Keep items away from the property that may attract rodents and wildlife, such as bird feeders, acorns, berries, woodpiles, decks in poor repair, holes in siding, etc.
