Is there a way that I can kill grubs in a lawn organically without using a pesticide? I've been reading about the soil food web and am trying to not use pesticides or synthetic fertilizers in my lawn. They have been a problem in the Saginaw Bay area this year. Is there a parasitic nematode or bacteria out there that's effective?

I applaud your efforts to walk softly and use the most effective, least toxic way of dealing with garden insects. Milky Spore Grub Control or Safer's Grub Killer are about as natural as you can get when it comes to treating for grubs. Milky spore disease (Bacillus popillae) was developed in the late 1930s as a biological control for Japanese beetles. It is used to suppress the population of Japanese beetles in turf and around plants. Milky spore disease is considered the best long-term control of Japanese beetles. Be sure to apply according to label directions.
