Agreed. Nature has the answer as usual. I've got two in my barn, no mice in my glue traps (those are inside the camper which is parked in the barn)
Moved one about 20 yards out of the way this weekend so he wouldn't get stepped on while we were working. Super docile for a rat snake, so I know they are eating well!
I also have those ultrasonic noise generators plugged in the camper but idk if those make a difference tbh
When I worked at zoos still, we had a guy who would come into the zoo and request lion poop to keep deer out of his garden.
Maybe some fox urine around... I know I made a garlic/4 kind of hot pepper/dawn dish soap (strained out peppers and garlic after letting marinate in the 90 degree heat for a day) that I put in a sprayer and sprayed around my garden - ground hogs wouldn't touch my garden any longer. Course, had to re-apply after it rained.
I know a lot about a little, and a little about a lot.
