One more yesterday, three more today--one in a cage trap and two in DPs. I've had three DP traps go missing this season, including one this morning. I have been using 3" deck screws into a tree (after removing bark layer) or large stump, and in each case the screw and the trap are missing. At first I thought they might be breaking the screws, but I've not seen evidence of that happening. It might also be a dog, coyote, human or lion providing some assistance, although I have no camera evidence that is happening in the area.I am going to try 3 1/2" marine grade screws with square heads, as I am tired of losing $14 traps--and don't like the thought of an un-dispatched cuffed 'coon.
As for as trap preference, I prefer the Duke and Minnesota Trapline traps to Wolf Creek Diablo's I am currently using. The WCDs are harder to set and the U-shaped ground stake is not suited for dry clay soil. The Duke's and MT's are basically the same, IMO. I have ordered 10 Tailfin R-Trap Dog Proof Raccoon Traps based on a recommendation, plus the price is right ($99 for 10, free shipping, not tax). I will post the results from these traps once they are set up.
