Stop in for a cup of coffee

A story to share. Went out to my storage twice the last couple weeks. I'm renting 3500 single story building. I had bait blocks out and went back the first time and half were gone, but no crumbs like something had eaten them. I put out more and same thing. I walked around and found a small cut hole in the floor and all the blocks were in the hole as if they'd been sweep in there including a very old dead mouse, and a dead bird.
I put the blocks back out maybe 25-30.

I went out the next day, yesterday, and everyone of them is gone. I had covered the hole with bricks so they weren't there. I looked and all the blocks were stuffed next to the battery in my 3/4 ton truck that I park there. I always leave the hood up just in case. I looked no crumbs or remints under the truck and with the splash guards don't know how in less than 24 hours a rat could do that much work. No rat dropping either around the battery.

So called my buddy who I rent from and he's shaking his head. I'm going to go ahead and get a couple good size traps, wire them down, and bait them today. One way or another I'll figure it out. Meanwhile my truck is here at the house.

Does this sound like a rat?? Can they work that fast. No real evidence on the floor either that they are in there.
