Yes, bleach can kill fleas, but it is not the most effective or safest method for flea control. Bleach contains strong chemicals that can eliminate adult fleas, their eggs, and larvae on hard surfaces. However, fleas often hide in carpets, upholstery, and pet fur, where bleach cannot be applied safely.
Using bleach requires caution, as it can be toxic to pets and humans if inhaled or ingested. It should only be used on non-porous surfaces like floors and countertops, followed by thorough rinsing. For better flea control, consider using veterinarian-approved flea treatments for pets, frequent vacuuming, and washing bedding in hot water. Pest control products like insect growth regulators (IGRs) are more effective in breaking the flea life cycle and preventing reinfestation.
