We are having problems with something that is making holes in our shed floor. the problem is the earth is brought up into the shed so it appears the whatever it is is digging its way out, rather than in. We have had rat traps set for a few days, but there is another pile of earth inside the shed again today. There is no food in there to attract anything. The holes are not big enough for it to be badgers, but a bit too big for mice. There are squirrels about, but I've never heard of them nesting underground.
Does anyone have an idea what we are dealing with.
