I have the most unusual mouse problem which is turning me into a crazy obsessed person and I'm hoping someone can help. We've had a random (and apparently individual) mouse getting in our house now for around 6 weeks which is proving impossible to trap. What makes it random is that it seems to be completely disinterested in any food. The first signs we saw were in upstairs bedrooms where no food is kept. He's been in the kitchen cupboards but hasn't been near any food, favouring cupboards containing things like pans. All the food is packed away in jars and tubs anyway, so there isn't anything to eat there even if he wanted to eat. He's never been near the kitchen counters as far as we can see, and since we first spotted the droppings we've been meticulous about cleaning and vacuuming every day so there isn't anything to eat anyway, though he doesn't seem hungry. The droppings are sporadic and few - we'll find a couple every few days speckled around, never more than about 4 or 5. The house is now literally filled with traps of every kind, from traditional snap traps, to the newer plastic snap traps (used as advised - against the wall in the areas we've seen droppings. We're tried back to back and perpendicular to the wall), to glue pads, to electronic zappers, to poison of two different types. We've tried peanut butter, biscuits, and chocolate, and even a mixture of the three as bait. He just seems to walk around it all. The cupboard he favours most I have literally tiled the floor with glue traps, yet he doesn't go near them. The poison is untouched. We've got sonic repellers in all the rooms. I've sprinkled peppermint oil around. We've filled every hole in the outside of the house that we can find, and even put mesh over the air bricks (though the house is semi-detached so its possible its coming in via the house next door). But he keeps coming back. HE KEEPS COMING BACK! What can we do? I'm reluctant to get in pest control if they are just going to put down more traps or poison and charge and arm and a leg for it. We can't get a cat due to allergies. Our house is old and has stripped floors which run under the kitchen cupboards and any number of gaps and places he can run around inside, so we can't stop him moving around the house without literally rebuilding. We live in London so mouse infestations aren't exactly a surpise and as a landlord have had to deal with them loads of times before, but I've never had any problems getting rid of them so this i really pushing me to the limits. Help. I am close to the edge!
