pest control

I am in east Tennessee and I am having trouble with a certain pest right now. It is the grape can girdler. I have been checking out information, like pdf's from various universities and etc., but they usually seem to just call them a minor pest and do not really recommend spraying. No articles are citing any particular sprays for them from what I have bee researching. They have cost me several small grape bunches already and I just do not want any more to be lost.
I have used some ortho stuff but I am seeing the bugs moving around like 5 mins after I spray them. Seems ineffective.
Can anyone recommend anything? Hopefully something home depot might have?

Seven or Neem oil

I will give that a try. Thanks

i don't have that particular pest but i use stylet oil to control pests and mildew. it is food grade organic method that you can use all the way to harvest. similar to neem oil got mine online.

What I have read is that you should tape off with plastic and duct tape the windows and doors. Then with a propane tank and burner they can be done away with. http://www.vdacs.virginia.gov/pdf/bb-heat1.pdf
