Cockroaches are quick to breed and multiply; once they get into your house, there is no easy way to get them out. They eat food, stain books and electric products, and some of them spread bacteria. Many people use insecticide to kill them, but if you have children or pets in the house, this could prove dangerous for their health.
Bay leaves are frequently used as a flavor in Spanish or Indian cuisine, but cockroaches hate its smell. If you place bay leaves in the kitchen, storeroom, garden, etc, cockroaches will stay away automatically, and children or pets will be safe.
