One thing to remember in field collecting as basic as it seems ...If you move it, roll it, or look under it ......put it back the way you found it. That is somethings home or was depending on the condition you leave it in:look:

I agree on the trash thing, carpet sets well thats another story, which I am guilty of on my land in Wisconsin, I catch and view many snakes there. This was a trick the boys at Strictly and a friend Dale tought me many years ago. In July last year I was in the cane fields south of the lake looking for critters.
I for the life of me can't understand the logic behind throwing a beer can down when if you save enough of them you can get more beer..
