Anyone else suffering from a surfeit of these rodents? We usually trap only one or two in the loft once every couple of years, but this year in the last fortnight we've trapped a couple in the loft and three in the kitchen. We don't leave food out, and can't work out where they're getting in to the kitchen, although possibly it's where the cable to the electric meter enters from the loft.
The SOT bit of DIY is in the baiting of the trap. Over the years we've used peanut butter to bait the trap, but for some reason the mice have mostly avoided setting off the trap (gentle licking, maybe?). I've had complete success so far with half a hazelnut pushed into the peanut butter. The peanut butter stops the mouse pulling the hazelnut free, so it tries to gnaw it in place by pushing down on the nut...
