Flea Life Cycle


It’s important to understand the complete flea life cycle so that you can best protect your pet and family members from infestation and infection. Not only will this information keep you well informed, it will help your when trying to eradicate the presence of fleas completely. And don’t forget, our Langley animal care clinic is here to help you with any questions you may have.

  • Adult fleas on your pet represent only 5% of a flea infestation life cycle.
  • The other life stages make up the remaining 95% and exist everywhere in your home that your pet has access to.
  • Female fleas lay up to 50 eggs a day in the coat of your pet. The eggs fall off into the carpet, furniture, bedding, and other areas.
  • Maggot-like larvae hatch from these eggs. They avoid light and will remain hidden in carpet fibres, bedding, and other dark places, indoors and outdoors, where your pet spends time.
  • The adult flea may emerge immediately from its cocoon or remain dormant for many months before emerging. This prolonged life cycle is the main reason why you may still see adult fleas on your pet and in your home for several weeks after the administration of a flea treatment.
  • Once fleas emerge from the cocoon, they will immediately seek a host. This can be your dog or even you. Within seconds to minutes after jumping on your pet, fleas feed and mate on the pet. Female fleas begin to lay eggs within 48 hours.
  • Adult fleas are just the tip of the iceberg.
  • Flea eggs and larvae can hide anywhere in your home.
