I have some grub control left over from both 2003 and 2004. I have kept it in a cool place and wrapped tightly. Do you think this would still be effective or should I discard it? If so, what is the best way to discard it with the least environmental damage? Thanks.

If this substance was stored properly as you said, it should be fine to use. Read the manufacturer's instructions for discarding the material if you decide not to use it.

I am also forwarding your question to Sandy Mason as this is really a horticulture question. She will likely reply privately to your email address, as she cannot post answers on the "family" section and I can not post answers in the "horticulture" section of this message board.
