If you're looking for ways to remove the rodents yourself easily, there are some simple, cost-effective ways you can try. These include
Create a 'bait station' to trap the rat (without harming it) and then release it safely away from your home. You can use foods such as dried fruits, nuts or even bacon to attract them.
Use a traditional rat trap. These can get purchased in local hardware stores.
Place peppermint oil, cayenne pepper, pepper and cloves around the home to keep them away.
Sprinkle crushed pepper, or spray a pepper spray, near openings and holes.
