Can one any one supply a non pesticide based mouse bait.? I can vaguely remember a bait which used plaster of paris but thats about all. Cats, cats and more cats. And a few more for good measure. In addition to the cats suggestion, fox terriers are brilliant! A lesser committment option is those mouse traps that are like a box (usually aluminium) and have a tunnel running through the centre which is irrestistable to the mice. When they run through the tunnel they get flipped into a holding chamber which they then cannot get out of. The best thing is that these traps can catch heaps of mice and keep catching them as they reset themselves. You do have to deal to the mice each morning though, as the thought of them dying of starvation inside the trap is not too flash. Very effective and safe for your other animals as there are no toxins and it is hard for bigger animals to get stuck in them.We get them here under a couple of brand names, but MouseMaster rings a bell and I am sure they are imported from or via Oz. Any good pet shop over there should have them as they are extensively used in aviaries because of the safety issue. Right I know this sounds really strange, but if your having problems with mice, one sure fire way to get rid of them is with the help of Gerbils. I used to keep pet gerbils ( I rescued them from a nearby school who didn't want them anymore) and with frequent handling they become very tame. Anyway when they became tame my gerbils were allowed to roam around the house freely (when there was someone at home to gerbil-sit) and when they became tired they would go back to their cage, which was placed in one area of my bedroom. I eventually left home taking the gerbils with me and shortly afterwards my parents complained that the house was now teaming with the local mouse population. They tried everything ( vegan friendly of course - I wouldn't let them try anything else) to rid their house but nothing worked. So one weekend I came home bringing the gerbils with me, and of course they knew the layout of the house so I let them out to play. Well naturally gerbils are very territorial animals and they go mad if they think another gerbil is in their territory, and they are even worse when it comes to mice. My gerbils picked up the scent of the mice straight away and went straight for their nests - I only know this because we could hear the fighting and back leg strumming from my gerbils. Gerbils will fight to the death, but because they are bigger then mice, the mice just gave up and left, we could hear them being chased out from under the floorboards, the whole thing lasted about 20 minutes. Now obviously I was worried about my gerbils dying, getting injured or picking up a disease but my guys came out without a scratch on them and as far as we know no mice died in their little adventure. That was 2 years ago and no mice have ever come back - so the gerbils seemed to have worked.
