How can fleas that have infested a house be removed? - briefly
Treat all pets with a veterinarian‑approved flea medication, wash bedding and upholstery in hot water, and vacuum every carpet, rug, and floor crevice, discarding the vacuum bag afterward. Follow by applying an EPA‑registered indoor flea spray or fogger, repeat vacuuming after 24 hours, and continue regular pet treatments to keep the infestation from returning.
How can fleas that have infested a house be removed? - in detail
Fleas establish a breeding cycle that includes eggs, larvae, pupae, and adults. Each stage requires specific conditions, so interrupting the cycle is essential for eradication.
The first step is to locate the source. Adult fleas hide in pet bedding, carpets, and cracks near floorboards. Inspect pets for signs of fleas—dark specks (feces) or live insects—using a fine-toothed comb. Remove any visible insects and wash pet bedding in hot water.
Next, treat the interior environment:
- Vacuum all carpeted areas, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister immediately.
- Steam‑clean carpets and upholstery to raise temperatures above 120 °F, killing eggs and larvae.
- Wash all removable fabrics (curtains, pillowcases, blankets) in hot water and dry on high heat.
- Apply an insect growth regulator (IGR) spray to cracks, baseboards, and under furniture; IGRs prevent immature stages from developing into adults.
- Use a flea adulticide (e.g., a pyrethrin‑based aerosol) on carpets and pet sleeping areas, following label directions for concentration and ventilation.
For pets, administer a veterinarian‑approved flea control product—topical, oral, or collar—ensuring continuous protection throughout the treatment period. Repeat the environmental treatment after 7–10 days, when the first batch of eggs has hatched, to eliminate the emerging adults.
Consider natural alternatives when chemical use is undesirable:
- Sprinkle diatomaceous earth (food‑grade) on carpets, leave for 24 hours, then vacuum.
- Place pheromone traps near baseboards to capture adult fleas.
- Use a diluted solution of white vinegar and water to mist pet bedding; vinegar disrupts flea respiration.
Maintain a preventive routine:
- Keep pets on a regular flea preventive regimen.
- Wash pet bedding weekly in hot water.
- Vacuum high‑traffic areas at least twice weekly.
- Seal gaps in flooring and foundations to reduce hiding places.
By combining thorough cleaning, targeted insecticide application, and ongoing pet treatment, the flea population can be eliminated and re‑infestation prevented.
