I like the 9x9 white plastic catch. Have caught lots of skunks in them. Never liked the PVC traps. just personal preference. But they get hot fast this time of year. They need checked early in the morning. Set one job where the owner called me after he gave the other guy a shot at it. The guys PVC traps were still there when I set. The next day the skunk was in one of my traps. Might have been the bait and lure that I used. Or happenstance.
I have never seen a pvc tube trap set the way Ron had his set and not catch a skunk, if it was a double door trap and the skunks were there.
There is a guy here, that never caught a skunk before or any animal for that matter. He caught 7 using a 6" double door tube set as forced sets or trail sets. I just saw him at the hardware store last week and asked him if he ever caught any and that is what he said.
