I was overwhelmed by borers years ago, that I never knew I had. When I realized what the problem was I was about to throw in the towel. It was supposed to be very safe and effective, so I used the grub control chemical for a couple of years and was happy to have found the answer. Well, you know what happened then. This chemical was found to cause bee deaths, and other nasty side effects. So I don't use it any more, (although I do have an unopened package of it that I guess I am saving for emergencies!) I am seeking out any suspicious activity and find a little here and there each year, but nothing horrendous. I don't know if I could have got to this low incidence of borer activity without the chemical though.
