The answer to 'when to treat for pest prevention' is that the best time to treat for pest prevention is on a regular, proactive schedule. This typically means treating for pests 2-4 times per year, depending on your location and the types of pests in your area. Treating on a consistent schedule helps prevent pest infestations before they become a major problem.
Treating for pests in the spring, summer, and fall is generally recommended to target common seasonal pests like ants, spiders, and rodents. Treating in the winter can help prevent overwintering pests from becoming an issue. Consulting with a professional pest control technician can help determine the optimal treatment schedule for your home.
