The answer to 'why is my flea nests' is that flea infestations often lead to the development of flea nests in your home. Flea nests are clusters of flea eggs, larvae, and pupae that accumulate in areas where pets sleep or rest, such as pet beds, carpets, and crevices. These nests can be a major source of continued flea problems if not properly addressed.
Flea nests occur when adult fleas lay eggs that hatch into larvae, which then spin cocoons and develop into new adult fleas. This cycle can continue indefinitely if the infestation is not controlled, leading to more and more flea nests forming throughout your home. Factors like pet bedding, carpeting, and cracks and crevices provide ideal environments for these flea nests to thrive.
