This mouse is one of a line which come in at intervals. We have a small hole in the larder which we thought we'd stopped completely - but obviously not... Mice can get through amazingly tiny apertures.

The "Little Nipper" is very efficient - the trick is to get the spring held at the very edge so that the slightest movement of the bait triggers it. It's very powerful and kills instantly - I've seen it at work.

Over the years we've found that peanut butter seems to get good results. Cheese is no good - and chocolate's too good to waste on a mouse! :-)
