How can I get rid of fleas in the house during hot weather? - briefly
Wash all bedding, rugs, and pet items in water above 60 °C and vacuum every room, discarding the vacuum bag afterward. Then apply an indoor‑approved flea spray or fogger, keep indoor temperatures above 25 °C and humidity low to prevent flea reproduction.
How can I get rid of fleas in the house during hot weather? - in detail
Eliminating flea infestations in a home when temperatures are high requires a systematic approach that targets both adult insects and their immature stages.
First, remove all sources of organic debris. Vacuum carpets, rugs, upholstered furniture, and floor cracks thoroughly; discard the bag or empty the canister into an outdoor trash container. Repeat the process daily for at least one week, focusing on areas where pets rest.
Second, treat all washable fabrics. Launder bedding, pet blankets, curtains, and removable cushion covers in water hotter than 130 °F (54 °C) for a minimum of 30 minutes. If the material cannot withstand high heat, place it in a sealed plastic bag and expose it to direct sunlight for several hours.
Third, control the indoor climate. Maintain indoor humidity below 50 % and keep ambient temperatures between 70–75 °F (21–24 °C). Low humidity disrupts flea development, while moderate heat prevents eggs from hatching.
Fourth, apply appropriate insecticides. Use a regulated spray or fogger labeled for indoor flea control, following label directions precisely. Target cracks, baseboards, under furniture, and pet sleeping zones. For households with children or vulnerable individuals, choose products with low toxicity, such as those based on diatomaceous earth or insect growth regulators (IGRs) like methoprene.
Fifth, treat the animals. Administer a veterinarian‑approved flea preventive—topical solution, oral tablet, or collar—to every pet. Repeat the treatment according to the manufacturer’s schedule to break the life cycle.
Sixth, eliminate outdoor reservoirs. Trim grass and vegetation around the foundation, remove standing water, and clear leaf litter. Apply a pet‑safe outdoor flea spray to shaded areas, focusing on places where pets frequently roam.
Seventh, seal entry points. Install weather stripping on doors, close gaps around windows, and repair cracks in walls or flooring to prevent new insects from entering.
Finally, consider professional assistance if the infestation persists after two weeks of diligent effort. Certified pest‑control operators can perform advanced treatments, such as heat chambers or targeted residual sprays, that are not available to consumers.
By combining rigorous cleaning, temperature and humidity management, targeted chemical or mechanical treatments, and consistent pet protection, a household can eradicate fleas even during the hottest months.
