I have some rats in my wood pile, I used the Victor (plastic) traps from Cabelas. When I first started using them I had 2 traps that went off 13 times and I had 13 rats!
I thought that these were the cat's ass traps, I decided to set up my trail cams to see them in action, I have videos of a couple large rats that will not touch the trap no matter what bait I use. I even made up one of those walk the plank into a bucket of water traps, the rat will eat all the bait tight up to where the plank starts to tilt and then they back off. These things get to be smart.
Think I might try one of those electric traps.
