When I was a kid I live trapped hundreds of skunks for a cottage association, never had one spray inside the trap, and I used large full sized traps... I would just drape a rubber matt with a slot in the middle so that I could reach the handle on the top of the trap... walked them down to the boat and reloacted them to a large uninhabited island... the locals still call it skunk island forty years later, even though that is not the name on the map. On days when the water was too rough to go across the channel, it was bad news for Pepe Le Pew... he only got to the lake shore.
In all those years, I only got sprayed once... I was tired and just decided to release a big, old skunk rather than dunking him... I opened the door and he took off, just as he was going around the corner of the shed, he let fly... nailed me full-on in the face. Little bugger.
