I like using the 11/2 trap, and my fav. set is a dirthole set
If there is alot of snow i go to a #2 trap has a bit more power
find some fox track or other sign and if you set where you know they are you prob. get one if you do not leave to much scent to keep your scent down wear some kind of gloves and rubber boots
like i said above i like using the dirthole set with Bait of your choice down the hole and some fox urine on the backing..
set on SIGN and you will have a great chanc at a red fox
