Fleas are tiny parasites that survive by feeding on your pet. They are wingless and travel by jumping from animals to find the next source of food.
A new adult flea finds a host (your cat or your dog) to feed on. After feeding on your pet’s blood and breeding, the adult female flea will then proceed to lay hundreds of eggs in your pet’s coat. These eggs will fall from your pet into the household environment – particularly where your pet spends a lot of its time (such as its bed or the sofa). The eggs hatch into larvae, before developing into pupae. The pupae then develop into adult fleas which look for a host and start the life cycle again.
