Fleas in a house from the basement, what should I do? - briefly
Inspect and treat the basement with an appropriate insecticide, then vacuum and launder all bedding, carpets, and upholstery throughout the home. Seal cracks, lower humidity, and repeat the treatment after two weeks to ensure complete eradication.
Fleas in a house from the basement, what should I do? - in detail
Fleas that have migrated from a basement into living areas require a systematic approach.
First, locate the source. Inspect the basement for rodent activity, pet bedding, or damp organic material that can sustain flea development. Remove any debris, vacuum thoroughly, and discard the vacuum bag or clean the canister with hot, soapy water.
Second, treat the environment. Apply an insect growth regulator (IGR) spray to cracks, baseboards, and under furniture in both the basement and upper floors. Use a flea fogger only if the space can be sealed for the recommended duration; follow the product label precisely.
Third, address pets. Bathe each animal with a veterinary‑approved flea shampoo, then apply a topical or oral adulticide that contains an IGR. Repeat the treatment according to the label schedule, typically every 30 days, to interrupt the life cycle.
Fourth, maintain sanitation. Wash all bedding, curtains, and removable upholstery in water above 60 °C. Vacuum carpets and rugs daily, disposing of the collected debris in a sealed bag.
Fifth, prevent re‑infestation. Install a moisture barrier in the basement to reduce humidity, which hampers flea development. Seal gaps around pipes and vents to limit movement of pests. Consider placing diatomaceous earth in low‑traffic areas as a non‑chemical deterrent.
Finally, monitor progress. Set sticky flea traps near baseboards and check them weekly. If counts remain high after three treatment cycles, consult a licensed pest‑control professional for a targeted intervention.
By executing these steps—source elimination, chemical treatment, pet care, rigorous cleaning, environmental modification, and ongoing monitoring—the flea problem can be resolved efficiently.
