Describe the 1st step of the life cycle of a flea

Fleas lay eggs in the pet’s environment (grass, carpet, crate bedding, etc)


Describe the 2nd step of the life cycle of a flea

The eggs hatch into larva (this can happen is as little as 48 hours depending on temp and humidity)


Describe the 3rd step of the life cycle of a flea

The larva forms a cocoon that hardens (pupa)

No chemicals can penetrate the pupa


Describe the 4th step of the life cycle of a flea

Pupa hatch into adult fleas


Describe the 5th step of the life cycle of a flea

The adult flea wants a blood meal and is on the pet/person in a short time to feed

Then they lay eggs and the life cycle starts all over again!
