Cover your trash: Make sure your garbage cans have snug lids and are made of metal. If you have to use plastic trash cans, make sure that there are no holes in them.
Store your pet food: Rats love pet food. If you feed your dog outside and leave food out, you’re inviting every pest in the neighborhood to visit. Store pet and bird food in glass or metal containers with tight lids.
Pick up fallen fruits: If you have fruit or nut trees, clean up any fruit that falls on the ground.
Clean up your garage: Lawn seed, tulip bulbs and bone meal are food sources for mice and rats. Store them in metal or glass containers with tight lids. Don’t store firewood in your garage because it is a potential nesting site. Organise and store boxes off the ground to eliminate places for mice or rats to burrow.
Use peppermint oil: Peppermint oil can be used to prevent rats as they can’t stand its pungent smell. All you have to do is dip some cotton balls in the oil and place them in the rat-prone area. It will surely give satisfactory results. Alternatively, citronella and castor oil can also be used.
Owl’s feather: Owl’s feather will scare the rats and force them to run away. Try placing some owl’s feather inside the holes of these intruders. Alternatively, if you can’t find one, keep some plastic snakes in your garden to get rid of rats in the yard.
Pepper: The pungent smell of pepper makes it hard for the rats to breathe and threaten their survival. Simply sprinkle some crushed pepper around the corners and the holes where they reside. You will notice positive results. Repeat the process if necessary. Onion also works. Just slice an onion and keep it inside or near their holes.
Human hair: This may sound weird, but rats can’t bear the sight of the human hair. Clip a few strands of your hair and throw them into the holes or places the ‘unwanted guests’ tend to visit the most. As the rats eat the hair, they will die.
Sound: Sound not only hurts them, but also makes their ears bleed. A sharp noise-making sound box is all you need to make them run away.
