there isn't really to many things out there that are cheap or free when it comes to having to get it in bulk. You cant just put 2 apples out or something so in general you have to have bulk of something. I think a good idea for you would be to make some kind of homemade liquid. Something you can dump or spray. They have that cmere deer stuff in liquid form, you can prob make something like that. Apple juice and crushed apples or corn something like that into a liquid and spray it all over your area. give it a shot. im sure if you look online somewhere someone has a recipe for something like that.
