Timing for applications of Merit 0.5 G Insecticide Granules will depend on the target pest being treated.
We recommend contacting your Local Cooperative Extension Office for advice on the best time to apply insecticides for pests in your region as they are a great resource when dealing with pests and most have a master gardener and an entomologist on staff to answer questions.
