Methods to Get Rid of Cockroaches in the Bathroom

Prevention Methods

  • Keep the bathroom clean and dry: Cockroaches are attracted to moisture, so regularly clean your bathroom and keep it dry.
  • Seal any cracks or openings: Inspect your bathroom for any cracks or openings in walls, floors, or pipes, and seal them to prevent cockroaches from entering.
  • Fix any plumbing leaks: Cockroaches are attracted to water sources, so repair any leaking pipes or faucets in the bathroom.
  • Store food properly: Avoid leaving any food sources accessible in the bathroom, as it can attract cockroaches.

Home and Natural Remedies

  • Baking Soda and Sugar: Mix equal parts of baking soda and sugar and sprinkle it in areas where cockroaches are likely present. The sugar attracts them, and the baking soda reacts with their digestive system.
  • Soap and Water Solution: Create a soapy water solution and spray it directly on cockroaches. This can suffocate and kill them.
  • Vinegar Spray: Spray a mixture of equal parts vinegar and water in areas where cockroaches are seen. Vinegar has a strong odor that repels them.
  • Lemon Juice: Squeeze fresh lemon juice and mix it with water. Spray this solution in the bathroom as a natural deterrent.
  • Boric Acid: Sprinkle boric acid powder in areas where cockroaches are active. This substance is toxic to them when ingested.
  • Diatomaceous Earth: Spread diatomaceous earth around the bathroom, particularly near potential entry points. The tiny particles in it can pierce the cockroach’s exoskeleton, leading to dehydration and death.
  • Peppermint Oil: Mix peppermint oil with water and spray it in the bathroom. The strong scent repels cockroaches.
  • Cucumber Slices: Place cucumber slices in areas where cockroaches are present. Cockroaches dislike the smell of cucumbers.

Commercial Products

  • Cockroach Baits: Use cockroach baits that contain poison. Cockroaches are attracted to the bait, consume it, and bring it back to their nests, effectively eliminating the entire colony.
  • Insecticide Sprays: Spray insecticides specifically designed to kill cockroaches in areas where they hide or move around.
  • Roach Motels or Traps: Set up roach motels or sticky traps in the bathroom to capture cockroaches.
  • Ultrasonic Pest Repellents: Use ultrasonic devices that emit high-frequency sound waves, which are supposed to repel cockroaches. However, the effectiveness of these devices is debatable.

Additional Techniques of Keeping Cockroaches Out

  • Keep the area clean and remove organic sources.
  • Seal cracks and crevices.
  • Fix plumbing leaks promptly.
  • Install door sweeps or weatherstripping.
  • Use screens on windows and vents.
  • Store bathroom supplies in sealed containers or cabinets.
  • Empty trash regularly with a tight-fitting lid.
  • Avoid leaving standing water.
  • Use natural repellents like essential oils.
  • Consider professional pest control if needed.


How do cockroaches get in the bathroom?

Cockroaches can enter the bathroom through various entry points. They are small and can squeeze through tiny cracks and openings in walls, floors, windows, or pipes. Common entry points include gaps around pipes, vents, or windows and openings around the edges of doors or drains.

What smells keep roaches away?

While cockroaches dislike certain smells, it’s important to note that they might not be completely effective in keeping them away on their own. Some scents that may repel roaches to some extent include citrus (such as lemon or orange), peppermint, eucalyptus, lavender, and cedar. However, these scents alone may not eliminate a cockroach infestation. Combining scent deterrents with other pest control methods is crucial for effective results.

Do cockroaches hate the light?

Cockroaches are generally nocturnal creatures, meaning they are most active at night and prefer dark environments. While they are not necessarily averse to light, they do prefer to hide in dark and secluded areas during the day. Excessive light may disturb them, but it is not a foolproof method for repelling or eliminating cockroaches.

Are cockroaches harmful to human health?

Yes, cockroaches can pose risks to human health. They are known to carry disease-causing pathogens, including bacteria, viruses, and parasites. Cockroach infestations can contaminate food, utensils, and surfaces, leading to the transmission of diseases such as salmonellosis, dysentery, allergies, and asthma. Additionally, cockroach droppings and shed skin particles can trigger allergic reactions in some individuals.

How do I keep roaches out of my bathroom at night?

To keep roaches out of your bathroom at night, seal entry points, keep it clean and dry, remove food sources, minimize clutter, use traps, and consider professional pest control if needed.
