I'm reposting this, which I wrote earlier as a reply, to make it easier to find. I also have a fox. I also belong to Defenders of Wildlife, so I'm not going to sit out there with a shotgun. Instead, I'd like to know if any of you have heard of or tried a method they promote to keep wolves from livestock that is called Fladry. It's extremely simple and cheap, a factor important to me since I can't afford to electrify our fencing. Apparently, wolf hunters in Europe have used this method for hundreds of years. They take a rope and tie red or orange strips of cloth to it at set intervals. They would then use these as fences to funnel the wolves to where they wanted them because the wolves won't cross this boundary, even when frightened. Defenders has taught ranchers and sheep herders to use this to "fence" in their stock when they can't watch for the predators and apparently it works great. I'm wondering if it might work for foxes. I've written to them to get an opinion. In the meantime, I'm going to take plastic grocery bags (Guess it's good that I occasionally forget my reusable bags!) and loop them onto the fence about 1 foot up. My sister-in-law and I are thinking that better yet, we'll put those obnoxiously loud Sun Chips bags (empty) in the grocery bags. That should scare off anything! Opinions?
