How Merit 2F Insecticide Works Merit 2F insecticide contains the active ingredient imidacloprid, a potent substance that affects an insect's nervous system. Once it's sprayed on the target area, the ingredient penetrates the leaves and the stems and works its way throughout the plant. An insect takes in the active ingredient as it feeds. Afterward, the ingredient prevents the pest from feeding and producing and then kills the insect as a result. Merit 2F offers long-lasting residual control and prevents further infestations long after the first application.
