It's one of the ugliest worms out there and they can destroy your entire lawn before you even know you have them. It's grubworm season and now is the best time to apply Hummert Grubworm Control to get those ugly worms under control before they can leave your beautiful lawn a huge mess. Grub worms destroy crops by eating away at the roots. An active infestation can cause a lawn to turn yellow and eventually brown as the roots are severed from beneath. The worms are commonly found in the topsoil of gardens and lawns and feed on the roots of grass, weeds, or vegetables often destroying crops and lawns. It only takes about 30 minutes to apply the granular grub control, so get it down now and protect your lawn all season!
