Re: Best traps
"So your choices are glue or patience and a pellet gun."
One of my first jobs was with biological supplier mostly dealing with schools*. One of the products was dead rats for dissection. Over the years a few had escaped and they bred. The head of the microscope slide section decided to stay in one evening with a gun and potted one. Then he remembered rat blood often has trypanosomes and went to fetch a syringe intending to make up some slides. He should have taken the dead rat with him; by the time he got back the others had dragged it away, presumably to eat.
After a little while they went bust. They'd invested in making microscopes just at the time the Japanese were moving into the school microscope market. It must have been one of the receivers' odder jobs. There would have been some strange assets. One of the set items for A-levels that year was a bull's eye. For weeks I'd been visiting the slaughter house and come back with bags of bulls' eyes. The schools had got wind of the impending doom so hardly any ordered them. There was a big vat of them steeping in formalin.
*at the same time SWMBO was a teacher. She reckons we still owe her some dissecting scissors.
