How Do Fleas Come Back?
WouterThere are two common reasons that fleas come back. First, they were brought into your home from another area with a flea infestation. Second, they need food once inside your home to reproduce. Since female fleas lose their fertility when feeding on human blood, they are unlikely to lay eggs on you. They need a preferred host in order to reproduce.
Fleas lay eggs two to three days after mating. These eggs hatch into larvae in three to six days. Once they have finished hatching, they remain in the area for another week or two. Then, they will need a new host to live in. However, they will still bite you if they don’t have a pet to feed on.
The best way to prevent fleas from jumping back onto your pet is to treat the environment where they live. Using a topical medication or a spray will kill the adult fleas, but won’t stop the larvae from hatching. You must keep your house clean to prevent the fleas from coming back. It is vital to vacuum often to remove the fleas in all stages of their life cycle.
Getting rid of fleas is difficult, so you must ensure that you take preventative measures. Vacuuming, cleaning the car interior, and changing pet bedding are important measures that can help you control fleas. Applying flea treatments according to instructions is also critical.
