For the past year, we have had quite a mole/vole issue. We’ve tried several different things that have only occasionally worked. We’ve gotten some castor oil to try and put around the food garden. I know that people take castor oil internally so I’m not concerned about toxicity, but if it will affect the crops in some other way, especially root vegetables. Last year they took out almost my entire potato and sweet potato crop. We were able to take up most of our raised beds and replace them after putting gopher wire beneath, but not all of our beds have this yet. So my question is 1) should I attempt to put a little bit here and there in the food garden beds or just around the walking paths of each bed to avoid the crops? And 2) if I do that, I was not planning on mixing with dish soap as instructed. Will it even be worth it? I would be using the dish soap in the areas out of the raised beds. Any thoughts or experience with this? Thanks!
