Flea extermination usually costs $150–$300 for a one-time treatment. However, because fleas reproduce rapidly, follow-up visits are sometimes necessary. Professional services use growth regulators and sprays to kill fleas at all life stages. They’ll also recommend cleaning, vacuuming, and treating pets at the same time to ensure success. DIY sprays rarely solve the problem because they miss eggs hidden in carpets or furniture. For complete flea control, call 866-204-0803 and schedule a pest control service.
