A female flea can lay more than 40 eggs per day

Can you believe that just a single female flea can cause a severe infestation in only two months? Actually, research shows that a female flea can lay more than forty eggs a day and they all can become adults if they develop in favorable conditions. 

“If you start with one female flea at maximum egg production, and assuming that half of the eggs are breeding females, in just 60 days you could have more than 20,000 fleas on your hands,” Morris explains. “This is how a serious infestation can happen before you even realize there is an issue.”
