I agree, the plastic "bait holder" is too slick, and it is therefore impossible to set the arm where it will stay. I have been using the sticky traps. The little furry critters step up on the trap and can't get away. You have to throw the trap out in the woods somewhere and let the little fellow get eaten by larger critters who also get stuck to the trap. I hate to do that and let the little fellows fend for themselves, but it is better than them getting into the car, etc. I also stuff very fine steel wool up into the A pillar so they can't get up into the header panel and piss on everything up there which subsequently rusts out the panel.
