Flea bites can result in severe itching and inflammation.  They can also cause skin infections, allergic reactions, and have the potential to spread diseases.


Did you know that:

  • Adult fleas are approximately 1/8 inch long and are laterally flattened.
  • They are reddish-brown, wingless and have 3 pairs of legs.
  • They can jump 150 times their own size.
  • A flea can bite up to 400 times in one day.
  • The female flea cannot lay eggs until after her first blood meal.
  • She will produce eggs within 24-48 hours of her first blood meal.
  • The female flea will lay around 400-500 eggs in her lifetime.
  • Fleas prefer humidity of at least 75% and temperatures of 70-90 degrees.
  • They live approximately 100 days.
  • Fleas are attracted to body heat, movement, and exhaled carbon dioxide.
  • They can spread diseases to animals and humans when they pierce the skin to feed.


The chart below shows the life-cycle of the flea:


The flea goes through 4 stages:

  1. The egg, which will hatch in about 2 days to 2 weeks.
  2. Larvae emerges from the eggs.  The larvae feed off organic debris, are blind, and keep to dark places.  This stage lasts 5-18 days.
  3. The larva will spin a cocoon and pupate.
  4. The adult will wait for the “right time” to leave the cocoon.  Vibration and carbon dioxide of a host passing by indicate the right time for the adult.  Once the adult leaves the cocoon its primary focus is to get a blood meal and reproduce.

Adult fleas only account for about 5% of the flea population.  The remaining population consists of 50% in the egg stage, 35% in the larval stage, and 10% in the pupae stage.  Because all these stages are present at once, it makes it difficult to control the flea population.  One flea can multiply into 1,000 in just 21 days.
