The answer to 'how long does flea treatment last' is that flea treatments typically provide effective control for 1-3 months, depending on the product and application method. Topical flea treatments for pets generally last 4-6 weeks, while flea sprays and foggers applied in the home may provide 2-3 months of protection. Ongoing prevention and monitoring is key, as flea eggs and larvae can continue to hatch and re-infest your home over time.
It's important to follow the instructions carefully for any flea control product, as improper use or frequency can reduce its effectiveness. Consulting a professional pest control technician can also help ensure the right treatment plan for your home and pet.
