Hi Chaps, just a few pointers for getting rid of "unwelcome Guests" in the shed or workshop. First off, rats etc will live within six feet of a food supply if they can, so remove any possible food source, keep dog/bird/pet foods in a metal container with a tight fitting lis, a metal dustbin is ideal if you keep a lot. plastic is useless, they WILL chew through it. Spray any areas that have seen activity/droppings etc with strong smelling disinfectant, I use jeyes fluid diluted and they don't like it. For trapping I use bait boxes, although the problem of them dying in inacessible places is a perrenial one, they work, and the smell only lasts a couple of weeks. Find where they are getting in and block it up. Clear any piles of junk or rubbish and have a really good tidy up inside and out, rats especially dont like having no "cover" they can quickly dart into. You can buy animal safe rat poison if you have pets, it is made from ground up maize husks and molasses, and is only poisonous to rodents, so if you have cats or dogs, use that instead of the commercial chemical poisons. If rats are getting in to your property from an adjacent one, like a neighbours/farms who have animals, and arent too careful about how they feed them, have a word, as this quicly can become an Enviromental health issue, although in most areas councils only deal with rats if you pay them, enviromental health rules can be used to get someone to clean up their act if you can show that the rats are coming from there! The reason rats and mice chew cables it that they think they are pipes! they will chew a plastic pipe until they make a tiny pin hole in it, and then drink there. I have replaced miles of Alkathene pipe, especially in old fashioned piggeries which had been gnawed all over the place. Feeding wild birds is a sore point, it is a good thing to do, obviously ( my mother does it, be she also gets rats in the shed!) If you can come up with a way of putting something under the bird feeders to catch the waste food, and recycle or otherwise get rid of it, this helps enormously. If you make them unwelcome enough, and starve them out, they will go looking for easier pickings. If they don't take the hint, poison the little buggers!
