well, found the smell

Back in March drove the coach to Las Vegas. I noticed a few miles from home at the service station a wet, musty hay smell. Looked underneath and there was a clump of straw hanging down. Living in an area and having straw around our property i assumed I drove through or the wind blew some underneath.

yesterday moved the coach to ready for a weekend adventure and after raising hood saw this.
It was buried down low, under the fuse box. Using mechanical pinchers I pulled it out a little at a time.

Well, having a variety of animals we know we have rats and mice. The bride encourages me to handle them in a humane way. i have tried the yeast mixtures, baking soda etc. On my night vision camera i see them giving me the middle finger.

This morning I ordered a pail of the irresistible green poison blocks and will strategically place them where they travel.

I inspected under and around and found no damage from chewing. I believe they left, maybe at 50 MPH when I drove the coach last time and have been living under the chicken coop.

Any suggestions or methods you use. The basic old traps may catch one then when louie doesn't come home they figure it out or maybe sneaking by and seeing his head smashed gives it away.
My crows enjoy them though,
