What element gets rid of fleas?

Diatomaceous earth is an effective natural element for getting rid of fleas. It works by dehydrating and damaging the exoskeletons of fleas when they come into contact with it. Additionally, essential oils like lavender and lemon can repel fleas, but caution should be taken as some oils may be toxic to pets. Regular vacuuming and washing of pet bedding also help in controlling flea populations.
