The best time to treat with Merit will depend on the type of insect that you are treating for and the region that you live in. We recommend contacting your local cooperative extension office to ask about insecticide timing for the pests in your region. These offices are an invaluable resource when dealing with pests and most have a master gardener and an entomologist on staff to answer pest insect questions. It is also a great idea to read through the Merit product label as the manufacturer may have provided information on the best time to treat for a particular insect.
