Trenton, KY | We have had trouble with voles for probably going on 20 years now. I don't really have an opinion that is scientific in the least, but I will say that we have fixed as many holes on lines that do have risers as ones that don't. I personally think they are chewing from the inside most of the time, because most of the holes we fix are at 10 and 2, like they are standing on the inside and chewing their way out. We don't know of any way to fix this problem, other than to keep digging! | |
