Flea Life Cycle

  • A female flea will lay eggs on a host (your pet) or directly in the bedding, carpet, or den. When eggs are not laid directly on the host, the area is called and environmental hotspot
  • Eggs will hatch into larvae and feed on dry blood and flea feces. The larvae may remain in this stage as long as 200 days!
  • After some time the larvae will spin cocoons and enter their pupa stage.
  • The pupa stage is the most tolerant stage and can last from 10 days up to 50 weeks as a pre-emergent adult, depending on environmental conditions.
  • Pre-emergent adults are stimulated to emerge by:


                        -Carbon Dioxide

                        -Movement (human or pet activity)

  • Without stimuli, emergence will be delayed

Their life cycle takes and average of 18-21 days, but may take 20 months or more depending on when the stimulant occurs.


Fast Flea Facts:

  • A single female flea may produce up to 4000 eggs over her life time.
  • Eggs hatch and develop into adults within only 3 weeks.
  • Flea eggs drop off from your pet’s coat and live undetected in the carpet, bedding, and other protected areas.
  • Fleas can be a carrier of tapeworm and if ingested by your pet the tapeworm will make your pet its host.


Clinical Signs:

  • Restlessness, biting, scratching, poor hair coat.
  • May cause anemia (blood loss causing lethargy) if the infestation is heavy.
  • Allergies to the flea’s saliva may or may not be present in your pet.
  • An intense itching sensation is usually seen on the lower back (near the tail), abdomen, neck, and inside the hind legs of dogs.
  • In cats, a red rash with small bumps and hair loss may result.
