So I know a lot of you have small coops, which I am very jealous of. I have a big ol' dusty spider infested barn instead. It's filled with spiders, everywhere and all over everything. I really hate spiders and the fact that there are so many is affecting how much time I would like to spend in the barn. Anyone have any home-made spider killers/repellents that are safe to use around chickens/goats/pigs/cows?
