To get rid of fleas in carpet, vacuum the carpet, sprinkle it with diatomaceous earth, vacuum it again, sprinkle the carpet with boric acid, work the acid into the carpet with a broom, and vacuum again. This procedure takes several days and requires a vacuum, latex gloves, garbage bags, a broom, a dust mask, diatomaceous earth and boric acid.
- Vacuum the carpet
Vacuum the carpet thoroughly. If your vacuum uses disposable bags, remove the bag immediately, seal the bag and set it outside. If your vacuum is bagless, take its canister outside, dump it in a garbage bag, and place a second garbage bag over the first.
- Sprinkle the carpet with diatomaceous earth
Sprinkle the carpet with diatomaceous earth. Leave the powder on overnight, then vacuum it up. Dispose of the vacuum's contents immediately. If the flea infestation is severe, repeat the diatomaceous earth treatment for several consecutive nights.
- Apply powdered boric acid
Put on a dust mask, and sprinkle powdered boric acid over the carpet. Scrub the powder into the carpet fibers with a long-handled broom, and leave the granules in place for three days. Vacuum the carpet, and discard the vacuum's contents immediately. If fleas remain in your carpet, repeat the boric acid treatment.
