Employing exclusion practices is important for many pest problems, but exclusion does not have a major, direct benefit for flea control. However, sealing cracks, gaps and holes to help keep rodents or other potential hosts from gaining access into the home is an important indirect way to keep fleas outside.
The most effective ways to keep fleas from getting inside the home is to eliminate outdoor flea habitats and outdoor hosts, plus using area-wide flea control chemical products and veterinarian-approved flea control products on pets.
