They'd rather have a trap bed get frozen and not educate a wolf versus having a working trap that gets dug up. Anybody else find this to be the case with canines?
I heard that too at the rondy and have to disagree with intentionally letting stuff freeze in. I'd rather have the trap bedded in waxed dirt and catch the wolf!!!
I take a lot of care with the dirt making and storage though and have never had a wolf dig up a trap, although I have had foxes dig up my wolf gear, right after getting it set. Generally I think the scent dissipates and it shouldn't be an issue, especially when talking about the length of time gear will probably be in the ground before a wolf shows up and all the fall rains we get.
The solar method of making WD is great. If it's going to be hot/dry for extended periods I just leave it on the tarp for a week or so. Learned the hard way to wrap it up at night or it attracts every barn cat for miles to the giant litterbox - and even then I haven't had issues. I store all my dirt in washed out metal trash cans in a shed, so there isn't really any chance for scent contamination. Making sure the dirt is absolutely bone dry before waxing is important too. Again, I leave the dirt sit for days in the hot sun and stir it over and over to make sure there's zero moisture. Not sure if that helps with the scent, but it'll prevent mold.
Personally I think the risk of using WD is far outweigh by the benefits of having a functioning trap.
