When Should I Apply Imidacloprid?

Although the bag often says apply anytime from May to Aug. 15, it is highly recommended that products containing imidacloprid, thiamethoxam, clothianidin be applied and irrigated into the soil in June or July.

When should I use merit grub control?

Late June to early August is the best time to apply a preventive insecticide. Several insecticides are available to commercial applicators for prevention of white grubs. Preventive insecticides available to homeowners include imidacloprid (Merit®, Grub-Ex®) and halofenozide (Mach 2®, Grub-B-Gon®).

Is it too late to treat for grubs?

Treating in late summer or early fall is ideal, as that is when the smaller, young grubs are most susceptible to nematodes. There is also usually a short window for application in early spring before the grubs get too big and pupate, but that is a narrower window and can be difficult to time properly.
