Hi, I have stopped having a pest control company spray in my backyard since we started keeping chickens. In that time, we have seen the spider population get crazy. I wouldn't mind so much, but it's mostly brown and black widows. I have young children, and a small dog.The spiders are in my fruit trees, along the fence, near the edges of the house exterior, heck, I even have to watch myself when I turn on the hose. I would like to know of something safe to spray that will eradicate the spider population without being dangerous to the birds. Anyone have any ideas?
