Thanks for the replies everyone!
Look under your yard light for similar droppings it might be toads but pictures have their limitations getting the size figured out. Think game cam if you have one.
I don't think it's toads because they were mostly on tables and in the loft. I could be wrong but it doesn't seem like toads would be climbing around on stuff like that.
Definitely rats. They appear to be roof rat feces. When they have the little tail on the dropping it is usually roof rats. They are great climbers. Check to see if the droppings are found at a higher level or elevation / beams loft etc..
They are mostly in the loft as well as workbenches
Those fresh ones come from Leprechauns.
What's the bag limit on them?
I tend to think it's rodent droppings. I think you might have some 110s around to set and see if you catch anything.
I think I just might have some

thanks again for those
By the time you catch the 54th one, they will have bred 100 more. lol
Best get a crap ton of good poison CC.
I'll hit 'em with a pile of stuff... traps, guns, poison. With the poison I gotta be careful I don't kill off any Leprechauns though
