I had a trap smart coon who defeated the live trap cage every way you can imagine.
Duke DP caught him first night.
Surprised Fleming doesn't provide trapping tips. Put the trap in the middle of a raccoon path, etc.
Get the set tool. The springs are strong.
The trap has to be fastened to something: tree, stake, buried anchor, etc. Otherwise the coon will run away with the trap.
BTW (1) look at the trapped coon to see if any sign of rabies (violent, foaming at mouth, spastic). Stay well out of reach if there are signs.
(2) there is no way to release the coon (I suppose you could wrap him in a moving blanket, but that would be very, very difficult with a highly likelihood of being bitten). Only way is to kill it.
