old chlordane for grubs?
My beautiful grass is turning yellow in spots and a neighbor suggests that it may be because of grubs. I put down some Grubex but now I'm reading that it's a preventive, doesn't kill active grubs, that I should be using Sevin or Dylox. I can go get some. But I'm wondering about using some old chlordane that's been stored in the basement for 40-50 years. It's one of those things you can't put in the trash because it's a chemical. So using it up by spraying the grass would help get rid of it. Will it work to kill the active grubs or is it more a preventive?
