A picture is worth a thousand words!
It's about 1.3cm (1/2") long. We rented a basement and I found this on a machine that was moved in a bit earlier.
I would like to know if there are any mice, rats, etc that could have come in.
We are on the island of Malta, in the Mediterranean sea. The basement is below a shop that used to sell AC units and the basement was used as a storage. The walls have gaping holes where cables and pipes go in and out, etc. Clearly industrial and not made for the customer to see.
