Flea Life Cycle
Stopping a flea infestation starts with understanding the flea life cycle
Fleas are tiny little blood suckers that can begin feeding on your pet in seconds. Within 24 hours of its first blood meal, a flea can begin laying eggs and can rapidly reach a rate of 40 to 50 eggs per day.1 The result? An infestation, which is why it’s critical to kill fleas fast—before they can lay eggs.
How did my pet get fleas?
There are many ways your pet can come into contact with fleas:
- Flea eggs can fall off a pet onto bedding and other areas of your home.
- Flea eggs drop to the carpet and mature into larvae, hiding in the carpet pile. Larvae turn into pupae, which may be dormant for months.
- Wildlife and outdoor domestic animals can be infested with fleas, dropping flea eggs in areas around your home. Newly hatched fleas may then jump onto your pet.
For optimum flea control, treat all pets inside and outside your home with an approved flea protection product on a routine basis. Learn about the health risks associated with fleas.
