This is quite a bit off topic of snakeoil, but when you talk about rodents control I actually think some of the things that kill mice are almost as bad as the mice themselves. I put skunks in this category as seems like every Fall I have a close call or bad experience with one or more of these at harvest time. I may have found an accidently good method for reducing the skunk population as noted this Spring just after seeding have found 3 dead skunks out in fields. It seemed a bit curious what was killing them, but noticed their proximity to some plugged opener checks of treated Barley and Peas and have to think that may be good skunk bait. I am sure it will not be too many more years before seed treatment will become as hated as gopher poison so probably should stock up.Only garter snakes here but give them the benefit of the doubt. I hate rodents. Even birds of prey I try to help them out. Don’t have rats but muskrats I do and seeing them crawling out of the water gives me the willies thinking they’re a rat. Anything which kills rodents are good.
