Natural Ways to Repel Cockroaches Without Chemical Sprays

Instead of relying on insecticides or commercial cockroach sprays, you can make use of natural, everyday ingredients found right in your home to keep these unwanted pests away. While chemical sprays are popular and often effective, they usually contain strong chemicals that may affect your health, cause unpleasant odors, or linger in the air and on surfaces. Natural alternatives, on the other hand, are safer, eco-friendly, and still remarkably effective when used correctly.

Below are several simple yet powerful home remedies that can help you repel cockroaches and maintain a cleaner, fresher living space.

1. Repelling Cockroaches with Essential Oils

To eliminate cockroaches in your kitchen, you can use natural essential oils such as clove oil, lemongrass oil, peppermint, rosemary, lavender, cedarwood, or cinnamon oil. These scents are pleasant and calming to humans, but cockroaches absolutely despise them.

How to use essential oils:

• Prepare a small dish of salt, add 5–10 drops of your chosen essential oil, and place the dish in areas where cockroaches frequently appear such as under the sink or inside kitchen cabinets.

• You can also diffuse essential oils throughout your home to prevent cockroaches from entering. This not only repels pests but also makes your home smell fresh and relaxing.

DIY peppermint cockroach spray:

Mix the following ingredients:

• 10 ml alcohol

• 90 ml water

• 20 drops of peppermint oil

Pour the mixture into a spray bottle, shake well, and spray in areas that cockroaches typically roam such as around sinks, behind appliances, or along kitchen counters. This solution is safe, non-toxic, and leaves the room smelling clean.

To increase effectiveness, you can repeat spraying every 2–3 days, especially during humid weather when cockroaches are more active.

2. Repelling Cockroaches with Chrysanthemum-Infused Alcohol

Chrysanthemums have a natural scent that cockroaches hate. You can make an easy, long-lasting repellent at home:

How to make it:

• Soak dried chrysanthemum flowers in white alcohol for one week.

• Strain the mixture and pour the liquid into a spray bottle.

• Spray it in areas where cockroaches frequently pass through.

This method not only drives roaches away but also acts as a mild disinfectant for surfaces.

3. Repelling Cockroaches with White Vinegar

White vinegar is a versatile household ingredient and also a strong cockroach repellent due to its sharp smell.

How to use:

• Mix vinegar and water in a 1:1 ratio.

• Pour the solution into a spray bottle and spray it around areas where roaches appear.

The vinegar smell forces cockroaches to flee immediately. However, since vinegar has a strong scent, remember to keep windows open for proper ventilation. You may also wipe down kitchen counters with this solution daily to maintain a cockroach-free zone.

4. Repelling Cockroaches with Citric Acid

Citric acid is a natural preservative often used in beverages and food products, but it is also highly effective at repelling cockroaches.

How to prepare a citric acid spray:

• 10 g baking soda

• 10 g citric acid

• 40 g water

Mix well and pour into a spray bottle. Spray this mixture on countertops, sinks, and drains. Leave it for 10 minutes before wiping clean with a cloth. This method helps block cockroaches from returning and also keeps surfaces cleaner and more sanitary.

For even better results, repeat this process once or twice a week.

5. Repelling Cockroaches with Basil (Holy Basil)

Basil has a strong, distinctive fragrance that cockroaches dislike. It’s an excellent natural repellent that is easy to prepare.

How to use dried basil:

• Take a handful of basil leaves and dry them completely.

• Place the dried leaves into a small cloth bag or a clean sock.

• Hang these sachets in areas where cockroaches often appear such as the kitchen, bathroom, or laundry room.

The stronger the basil scent, the more effective it becomes. Over time, you’ll notice a significant reduction in cockroach activity.

6. Repelling Cockroaches with Soap Solution

A simple soap solution can also help eliminate cockroaches.

How to use:

• Mix 20 ml liquid soap with 500 ml water.

• Place the solution in small open containers around the kitchen or apply it directly to areas roaches frequent.

The scent of soap repels cockroaches, and if the mixture comes into direct contact with them, it can even kill them by blocking their breathing pores.

Important Tips to Prevent Cockroaches from Returning

Even if you use natural repellents, the most effective long-term solution is to remove their food sources and hiding places:

• Keep food stored in sealed containers or inside the refrigerator.

• Cover all trash bins tightly to prevent odors from attracting roaches.

• Clean spills, crumbs, and grease promptly—these are major attractants.

• Fix any leaks in pipes or sinks, as cockroaches thrive in moist environments.

By maintaining a clean home and using these natural remedies regularly, you can significantly reduce cockroach infestations without relying on harsh chemicals.
