Fleas are tiny, resilient pests capable of entering homes through various openings, and windows are no exception. While fleas are most commonly introduced into homes via pets, they can also enter through windows if the conditions are right. Fleas are highly adept at jumping, which allows them to move from the outside into a home through open or poorly sealed windows. Additionally, fleas can be carried into homes by wind, or they may hitch a ride on birds or rodents that nest near window sills or cracks.
Windows that are left open without screens or those with damaged screens provide easy access points for fleas. Once inside, fleas seek out hosts—typically cats, dogs, or even humans—to feed on and may quickly multiply in the right conditions. Flea infestations often start outside in tall grass, gardens, or areas where animals frequent, and open windows can serve as a pathway for these insects to move indoors (Jones, 1950).
Fleas can also be brought indoors by animals that rest or sleep near windows. The fleas may jump from these animals and make their way inside. Once indoors, fleas can hide in carpets, bedding, or cracks in the floor, where they reproduce rapidly. Therefore, ensuring that windows are properly sealed, and screens are intact can help prevent fleas from entering homes.
