Apply a certified flea‑killing spray directly to the floorboard gaps and seams, then vacuum the area and discard the vacuum bag. Repeat the treatment weekly for three weeks and maintain regular cleaning to prevent re‑infestation.
How to eliminate fleas in a house’s floorboards? - in detail
Fleas often exploit the voids and moisture typical of wooden subflooring, making eradication a multi‑stage process.
Identify active sites by inspecting baseboards, seams between boards, and any visible droppings or bite marks. Use a bright flashlight and a fine‑toothed comb to detect adult fleas or larvae in cracks.
Prepare the area before treatment. Remove rugs and furniture, then vacuum thoroughly, focusing on edges and crevices; discard the vacuum bag or clean the canister immediately to prevent re‑release. Seal visible gaps with caulk or expanding foam to limit refuge spaces.
Apply insecticidal products designed for indoor use. Spray a residual aerosol or apply a powdered formulation directly into the cracks, following the manufacturer’s safety instructions. Ensure coverage of both the surface and the underside of each board.
Employ non‑chemical measures as complementary controls. Distribute a thin layer of food‑grade diatomaceous earth across the floor, allowing it to infiltrate gaps; the abrasive particles desiccate fleas on contact. For heat‑sensitive stages, raise the ambient temperature above 95 °F (35 °C) using portable heaters, maintaining the level for several hours to eliminate eggs and larvae.
Implement a monitoring schedule. Re‑vacuum weekly, re‑apply insecticide or diatomaceous earth after two weeks, and inspect for new activity. Prevent recurrence by treating pets with veterinarian‑approved flea preventatives, maintaining low indoor humidity, and performing regular deep‑cleaning of the flooring.
