When we were first married we lived in a 2 hundred year old, decrepit cottage, and we were overrun with mice. I found out for certain one day when hubby asked for corn flakes for supper. I put the bowl on the kitchen table, got the corn flakes out of the old wooden cupboard on legs that we kept our food in, tipped it over the bowl,.........and a mouse ran out! It ran across the table, jumped onto the floor, and disappeared under the door leading to the cellar steps. I used to put his sandwiches for work up before going to bed, and wrap them in waxed breadpaper and place them on top of said cupboard , in front of the breadbin, till the mice started chewing their way in, then I put them into the pocket of his work coat, hanging benhind the front door, but the cheeky little buggers went in there as well! One evening, after supper, himself left his plate lying on the rug in front of the fire. After a few minutes, 2 mice approached, from different directions, climbed onto the plate and started licking it! Hubby moved his foot ever so slightly and they were gone! I didn`t want to hurt them, they were so cute, but after finding droppings in the drawers, and with a baby on the way, there was no choice. He started by placing a plastic bucket, with an inch of water in the bottom, under the cupboard where they`d been getting in through a teeny, teeny crack in the back, and every morning there was a dead mouse in there.
In later years, and houses, we had cats, so never any problems, but about 4 and a half years ago, we had one in the living room, saw it a few times over a couple of days, put humane traps down, but no joy, then it wasn`t seen anymore, don`t know what happened to it. Then the other day, I saw one streak across the opposite corner of the living room, but haven`t seen it since. No droppings either, so hopefully it was just a fleeting visit.
