There are several things that you can do to keep them away from your house. 1. Inspect your house and its surrounding for signs of infestation: Droppings, gnaw marks and tracks are the most obvious indications of a mouse infestation. 2. Always make sure doors and windows are properly closed: Always keep the doors of our house closed to prevent unwanted guests from entering. Windows should be shut whenever there is no one home so that you will not come back home to find "new tenants" in your house. 3. Seal up all possible entry points of mice: Mice are so small and their bodies are so flexible that hey are able to squeeze through openings that are as small as 1/4 inches across. The possible entry points may be gaps around pipework, holes on the roof or even the gap between doors and the floor. All openings that may serve as entry points for mice should be sealed with materials that cannot be gnawed down by mice, for example, cement and wire mesh that is smaller than 1/4 inches to deny their access. 4. Keep all food airtight: A mouse will feed on whatever humans eat. By leaving your food uncovered, you are making your house vulnerable to the infestation of various pests such as mice, ants, flies and cockroaches. 5. Dispose of food wastes properly: Mice are not as picky as we are when it comes to food. They will be attracted to, and happily feed on , the food wastes we leave behind. Proper disposal of food wastes is important as it will make your house less favourable to them due to the lack of food sources. 6. Get rid of possible nesting sites for mice: A house mouse nests in sheltered locations and constructs its nests using shredded paper and other fibrous materials. By cleaning all rubbish and sealing all holes or cracks around your house, you can prevent sharing your house with these sneaky critters. 7. Use traps: If your house is already infested with mice, traps can be deployed to remove them from your house. Some of the traps that can be used include snap traps, glue traps, cages and electrocution traps. Traps should be placed behind objects, in dark corners and at edges near walls because mice tend to move about touching the wall.
