The optimal time for termite treatment depends on various factors, including the species of termites, local climate, and construction type. Generally, treatments are most effective when performed during the termite swarming season, typically in spring or early summer. This period coincides with increased termite activity and colony reproduction, making them more susceptible to treatment. However, it’s crucial to consult with a qualified pest control professional to determine the most suitable time for termite treatment based on specific conditions.
