The fly bait powder or liquid is the absolute best way to rid yourself of unwanted pests. We use it to control woodchucks, skunks, coons, coyote, and opossum around the barn yard. We use a slightly different delivery than you have mentioned. We put it in an old bowl with a half can of Coke and stir it up. These scavengers will lap it up since its sooo sweet, and the rotten bast***s won't even make it 20 feet before they flop over. When you find a whole litter of chucks, put this stuff out and the next day you'll have 10 of them in a big circle around the bowl.
Word of caution: If you have cats, dogs, kids, or any other living creature in the target area, DO NOT USE THIS STUFF!!!!
I'm sure it's not legal and the feds are tapping my phone as I type this, just as PETA is staging a demonstration outside my home.
Oh well, I'll send you messages from the big house.
