Thought I would share some interesting feedback about Grazers from Canada.....
"In the early spring there were deer eating tulips etc. in the garden. So I sprayed just about everything, especially the raspberry patch. The deer then seemed to stay away since there was nothing nice to eat. We had very few deer all summer. Apparently we used to have a cougar in the area, which keeps the deer population in check, until he made the mistake of taking off with a neighbour's goat! I hope you are able to export to Canada for you do have a good product."
