Orange and Lemon Peels
One of the effective ways to repel cockroaches is to use orange and lemon peels. Cockroaches detest the aroma of essential oils that orange and lemon peels emit. Therefore, you can dry and grind these peels and place the powder in areas where they frequently appear. Alternatively, mix lemon juice with a little water and spray it in places where these pests tend to gather.
Garlic
The pungent odor of garlic is a nightmare for cockroaches. Its strong scent can help drive them away. Simply place or sprinkle garlic powder in the cockroaches’ path, and they will find a way to escape your home. A small amount of garlic powder is easily dispersed by wind, so be sure to place it in enclosed areas.
Onions
Onions have a similar pungent smell to garlic. Their sharp, spicy aroma is off-putting to cockroaches. Thinly slice an onion and place it in areas where food is frequently stored, and the cockroaches will be repelled.
Alum
The distinctive smell of alum is something that cockroaches detest and will want to avoid. Simply dissolve some alum in a bucket of warm water and use the solution to mop the floors. As the floor dries, the alum water will seep into the crevices and leave behind a scent that cockroaches find repulsive. With consistent application, you will notice a significant reduction in cockroach activity in your home.
Coffee Grounds
While the aroma of coffee may attract cockroaches, the caffeine in coffee can actually kill them. To utilize this method, mix coffee grounds with water and place the mixture in small containers with lids. The cockroaches will be lured by the scent and crawl into the containers. Once they are inside, secure the lids and wait for them to perish.
Bay Leaves
Bay leaves are a common cooking ingredient, but cockroaches detest the scent they emit. Therefore, using bay leaves is a safe and effective way to repel these unwanted pests from your home.
Baking Soda
In addition to its cleaning properties, baking soda is also effective in killing cockroaches. To get rid of them, mix baking soda with a small amount of flour, food, or sautéed shallots to attract the cockroaches. The baking soda will cause toxicity and death in cockroaches after ingestion.
