Hi Mary,
I too have been dealing with grubs and refuse to dump chemicals onto the
lawn where my children play. I am about to spray nematodes which will kill the grubs and I am also using milky spore for future prevention. If you have a serious grub problem milky spore won't help immediately, if you research it you'll get a better idea . But apparantly nematodes
should get it all under control within a few weeks by killing larvae and such. I hope so!! I will let ya know! I bought my nematodes and milky spore from dirtworks.net good stuff and informative too.
This website is awesome and I am embarking on quite a lawn
project with much confidence thanks to Paul's helpful replies and advice. Good Luck!
