Roaches dislike certain natural scents because they have a strong sense of smell that they use to find food and navigate their environment. Here are some scents that can repel roaches:

• Lavender: Roaches hate the smell of lavender, which can be used as a natural roach deterrent. You can plant lavender around the outside of your home or mix lavender oil with water and spray it around your home.

• Mint: Roaches dislike the strong smell of mint, so using this scent in your home can be effective in keeping these pests away. You can grow fresh mint plants in your home or mix peppermint, winter mint, or spearmint essential oils in a spray bottle with water and spray around baseboards, windows, and doors.

• Citronella: Roaches hate the smell of citronella, which is commonly used in insect repellents. You can buy citronella oil in oil form to spray around the house or plant citronella plants on the outside of your house and keep potted plants indoors.

• Oregano: Oregano is one of the most powerful scents that cockroaches hate. You can add a few drops of oregano oil to a spray bottle with water and spray generously on infested areas. Oregano can also be grown in planters and gardens to keep pests away.

• Garlic: Roaches dislike the strong smell of garlic. You can place whole cloves around the kitchen or sprinkle garlic powder in areas where roaches are likely to be found.

• Cinnamon: Roaches dislike the smell of cinnamon. You can sprinkle cinnamon powder in areas where roaches are likely to be found.

• Bay leaves: Roaches dislike the smell of bay leaves. You can place bay leaves in areas where roaches are likely to be found.

Its important to note that relying on essential oils and herbs may not be enough to deter every kind of cockroach or pest. Therefore, its recommended to use these natural scents in combination with other pest control methods, such as keeping your home clean and free of food debris, sealing cracks and crevices, and using traps and baits.
