Target, eliminate and control pest infestations with Merit 0.5 G insecticide. The "G" stands for granules, delivering a powerful ingredient to kill invasive and turf-damaging insects on many different sites, from recreational fields to home lawns. It spreads easily and works more efficiently after irrigation or rainfall. Whether it's chinch bugs or mole crickets, Merit 0.5 G insecticide kills them quickly and effectively.

How Merit 0.5 G Insecticide Works

Merit 0.5 G insecticide contains imidacloprid in a granular form to target turfpests in residential, commercial and recreational areas. This active ingredient starts to work upon ingestion and prevents the insect from feeding, causing the pest to die. Because Merit contains more of the active ingredient than similar insecticides, it provides more effective results and lasts for up to six weeks. With the right conditions and application rates, it can control white grub larvae for nearly four months.

Where to Apply Merit 0.5 G Insecticide

Apply Merit 0.5 G insecticide with a spreader over turf in commercial and residential settings. It works to keep June beetles off home lawns and grubs off golf courses. Use Merit 0.5 G on turfgrass in the following places and more:

  • Airports
  • Business landscapes
  • Cemeteries
  • Office complexes
  • Parks
  • Playgrounds
