Fleas are quite hard to control quickly and most people see a problem get worse after treating since the chemicals agitate the flea larvae and adults to move around more. Once the flea emerges from the cocoon it will begin feeding within a few hours and shortly after, the adult flea will mate immediately. An adult flea will lay about one egg per hour and about 50 eggs per day. In ideal conditions, the flea completes its life cycle in as little as 12-14 days. While fleas are in the egg stage they are impervious to insecticides. It is not until they hatch that the insecticides have a chance to work their magic. That is why any treatment for fleas cannot be 100% effective for 14 days. Thankfully, ABET has all the professional tools and products to successfully eliminate your flea problem.
