Product Description: Imidacloprid 2F Insecticide is a systemic insecticide we love to use as our go-to for grub prevention. Grubs are the larvae of various June beetles (June Bugs) the eggs are laid in the lawn through May, June, and July, possibly into August. They can be a real problem, especially after a mild winter. Grubs damage lawns in every part of the country, from northern cool-season lawns all the way down south to warm-season lawns.
The key to keeping grubs at bay is getting Imidacloprid down prior to the grubs feeding. We recommend you apply Imidacloprid in mid-May and get it watered in (must be watered in with ½” of rain or irrigation) and this will prevent grubs for up to 4 months, which is plenty of time to protect your turf from grub damage. Imidacloprid can also be used to prevent other lawn insect problems, such as chinch bugs suppression, mole crickets, emerald ash borer damage, and other insect problems in your trees and shrubs. Please see the product label for more information.
