coon problem

I was having the same coon problem at a place on the river we were trapping hogs. The place isn't big enough to run dogs on, but the lady wanted the hogs caught so I was trapping them. Caught several hogs, then the coons found the traps. Since then I can't keep the coons out of the traps long enough to catch any hogs. They either trip the traps (both have drop doors) or eat all the corn before it even gets dark. There must be a pile of coons as they have a beat down path from the river to both traps.

I have soured the corn and I have poured diesel on the corn and neither has even slowed them down. I set a gallon milk jug of corn, soured in water and diesel in the trap and the coons ate it all including the milk jug!

Any suggestions anyone??
