get rid of grub worms?

Answer 1

In the upper Midwest, there are three primary white grubs that infest and damage lawns. They are the Masked Chafer, Japanese Beetle and May or June Beetles.

Milky spore is a bacteria that affects only Japanese Beetles. If your goal is to control all grubs in your lawn, then milky spore would be a poor choice. Beneficial nematodes (Heterorhabditis bacteriophora) attack all white grubs and is an effective, natural, & safe biologocal control alternative to Milky spore or pesticides.

Insecticides available for homeowners include diazinon (25% EC [liquid] or 5% granular); trichlorfon (Dylox) (6.2% granular); bendiocarb (Intercept), halofenozide (GrubBGon, GrubEx), or imidacloprid (Merit, formerly GrubEx) for control of white grubs.

All control mechinisms work best if applications are timed to the life cycles of the specific grubs in your area. Here is a good article from the University of Illinois Extension on grub control: http://www.urbanext.uiuc.edu/lawntalk/lawntalk23.html

Check out the University Extension site in your area for their specific recommendations on grub control in your area.

Answer 2

There are poisons made by companies by Scott that can be watered into the ground.

The better idea is the biologicals that you water into the ground that make the grubs sick, like Milky spore disease powder. They are harmless to people, animals, birds and are organic and safe for food crops. Once the first grubs catch the disease and die, their bodies are filled with spores that then infect nearby grubs. The original application is viable for 10-15 years.
