 Okay. I don't know how well it would work outside. It does, because I had a billion of these little teeny tiny ants, and they were coming up in my brickwork where I parked my truck alongside my house. And I said, I'm afraid I'm going to get them on my shoes. I'm going to drag them inside. So I went and I got one, and I put it outside. I came back. I did it in the afternoon. I came back to get my truck in the morning, and they were gone.
