To get rid of mice in homes, there are various steps that are to be undertaken. First you need to stack the fire wood about 18 inches off the ground and that should be kept away from the buildings. You should always keep the dustbins covered. You need to keep cleanliness of your yards and alleys. You should never compost any animal products as they feed the rats. Rats normally live in the small holes. Use the rodent resistant composters. These should be kept near all the openings that are there in the house. The rats should be wrapped properly once they are dead and thrown away from the house. They should never be killed with toxic pesticides.
A little Home Remedy that I've picked up :) If you plant mint around your house it keeps them away also you can use peppermint oil and soak a cotton ball leave those around the house especially if you know where there popping out of.
Once you have mice in your house you have a problem - but not one that cannot be over come. You can employ the services of a hungry cat, a mouse trap or you can use a more humane trap such as a plug in high pitched siren.
Let's start with the cat - they can only eat so many mice in one sitting and they do tend to leave entrails on the floor when eating them (not nice I know, but true!) Next is a mouse trap. Be careful when setting them as they tend to hurt when they snap. It's best to load them up with chocolate not cheese, and it's best to smear them with a chocolate spread not chunks of chocolate! Place them along the skirting board but be warned mice soon learn to jump over them, so place two or three in a row to catch the beggars!
Finally the sonic plug-in things are very good at chasing the mice away. They emit a really high squeak that mice hate but humans can't hear. They don't permanently hurt the mice and just encourage them to stay away. Once they are gone, block up all holes to the outside of the home except air bricks and ventilation shafts etc. Then just be vigilant and keep all food stuffs in plastic sealed containers away from the mice.
