The female flea lays 20 to 30 eggs a day on the host pet. The eggs rarely stay on the pet; they drop to the ground in areas the pet frequents. Once on the ground, the eggs hatch in two days. Eggs often become embedded in the crevices of the wood pieces and along the skirting boards in hardwood floors. Treat the host pet with flea shampoo and topical treatments, then focus on killing the fleas in the home. Treat the floor promptly to kill the fleas, larvae and eggs.
Vacuum the entire hardwood floor. Use a vacuum attachment to reach into the corners of the room and along the skirting boards where the wood flooring meets the wall. Empty the vacuum bag into a bin bag and promptly dispose of it outside.
Lift all throw rugs and pet beds off the hardwood floor. Wash them in hot water with washing powder and dry them before placing them back on the hardwood floor. Vacuum the floor thoroughly in the area where the rugs and pet beds sat before placing the rugs and pet beds back on the floor.
Spray a growth regulator insecticide that contains methoprene or pyriproxyfen on the flooring, skirting boards, crevices, furniture and rugs. The growth regulator controls the larvae of the flea and prevents the insect's growth. Repeat the spraying process in three weeks.
Sprinkle a light dusting of boric acid and diatomaceous earth across the wood floor daily. The substances help to promptly kill the flea without harming humans or pets. Allow them to remain on the floor overnight and then vacuum the hardwood floors daily for up to one month. Always take out the vacuum bag and promptly dispose of it.
Keep all children and pets off the hardwood floor after it has been sprayed with growth regulator until the surface dries.
