How it Works
Imidacloprid, the active ingredient in Merit, is a chloronicotinyl insecticide. Imidacloprid binds to the acetylcholine receptor in the insect nervous system, thus preventing normal transmission of nerve impulses. This mode of action results in disruption of normal behavior; treated insects stop feeding, do not reproduce and eventually die.



FAQ
Q: When is the best time to apply Merit for white grub control on turfgrass?
A: Merit is most effective when applied prior to, or just after, egg lay. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Merit will provide residual white grub control for four months or longer in turf.

Q: Does Merit control all major white grub species?
A:Merit protects turf from all major white grub species, including superior control of the major grub species: Japanese and oriental beetles, European chafer, and northern and southern masked chafers. Merit also controls green June beetles better than other insecticides used for turf and ornamentals.
