There are several natural and homemade remedies that can repel cockroaches. Here are some of the most effective ones:

• Cayenne, Garlic, and Onion Powder: Sprinkle this spice mixture around your home in cockroach-prone areas. Cockroaches cant stand the smell of these spices and will avoid all areas sprinkled with them.

• Tea Tree Oil: Mix 1/4 cup of tea tree oil with 2 cups of water in a spray bottle and spray it throughout your home.

• Borax and Sugar: Combine three parts borax to one part sugar and sprinkle it around your home to keep the roaches at bay.

• Diatomaceous Earth (DE): Sprinkle DE around your home or use it as bait in concentrated areas where you are experiencing roach issues. When roaches come into contact with DE, it dehydrates their exoskeletons.

• Peppermint oil, Cedarwood oil, and Eucalyptus oil: These essential oils have strong scents that seem to have some success in repelling roaches. You can dilute them with water and spray areas you think cockroaches might have nested.

• Boric Acid: This powder dehydrates the exoskeleton of cockroaches until they die. Sprinkle it around your home to keep the roaches at bay.

• Soapy Water: Dousing a cockroach in soapy water will suffocate and kill it. Filling a spray bottle with dish soap and water, shaking it, and spraying a roach from above will kill it quickly.

• Traps: Glue traps or poisonous roach traps will capture and kill cockroaches quickly.

Its important to note that while these remedies may provide a limited level of deterrence, their effectiveness is generally lower than chemical repellents. Severe infestations will likely require the help of an expert pest management team.
