No one wants cockroaches in their home. These creepy crawlers are not only unsettling to see but also carry harmful bacteria, trigger allergies, and are notoriously hard to eliminate. While store-bought sprays may offer a temporary fix, they often come with chemical fumes that aren't safe for your family or pets. The good news? There are natural, effective, and affordable remedies you can use to take back control — and they actually work.
Let’s dive into the most effective home-based techniques that can kick cockroaches out for good. These 7 home remedies are time-tested, easy to make, and safe for everyday use.
1. Baking Soda and Sugar Combo
When you mix baking soda and sugar, you're creating a simple bait-and-kill strategy. The sugar attracts the roaches, and the baking soda reacts with their stomach acid — causing them to die from internal pressure buildup.
- Mix equal amounts of baking soda and powdered sugar.
- Sprinkle the mixture in roach-prone zones like behind the refrigerator, under the sink, and near drains.
- Repeat every 2–3 days. Replace the mix if it gets wet.
This remedy is perfect for kitchens where you want to avoid strong pesticides around your food prep zones.
2. Bay Leaves – Natural Roach Deterrent
Bay leaves are commonly found in most kitchens and have a pungent aroma that cockroaches despise. They won’t kill roaches, but they will drive them away from specific areas.
- Crush dry bay leaves into powder for maximum potency.
- Place in corners of cupboards, inside drawers, and on shelves.
- Replace every few weeks as the scent fades.
It’s a non-toxic solution — perfect if you have kids or pets at home.
3. Boric Acid and Flour Paste
Boric acid has been used for decades to deal with cockroach infestations. When consumed, it poisons their digestive system and damages their exoskeleton.
- Mix 1 part boric acid, 2 parts wheat flour, and a pinch of sugar or cocoa powder.
- Form small dough balls and place near the back of cabinets, under stoves, and around garbage areas.
- Always use gloves and keep out of reach of children or pets.
This method works slowly but can significantly reduce cockroach populations over time.
4. Diatomaceous Earth – A Silent Killer
Diatomaceous earth (DE) is a powder made from fossilized algae. It's razor-sharp on a microscopic level, slicing through roaches' exoskeletons and dehydrating them.
- Choose food-grade DE only — not the one for pools!
- Sprinkle along floor edges, behind appliances, and where walls meet the floor.
- Leave overnight and vacuum up excess the next day.
It's safe, silent, and super effective in dry environments.
5. DIY Garlic-Onion-Pepper Spray
If you're okay with a bit of smell, this homemade spray is a great barrier. Roaches can’t stand it and will stay away from treated surfaces.
- Blend one garlic clove, half an onion, and one teaspoon of cayenne pepper in two cups of water.
- Let it steep for an hour, then strain and pour into a spray bottle.
- Spray under sinks, baseboards, and near plumbing lines.
For best results, reapply every few days or after cleaning the area.
6. Lemon Juice Floor Cleaner
Lemon juice is a natural roach repellent that also works as an antibacterial cleaner. It leaves surfaces sparkling and unwelcoming for pests.
- Mix the juice of two lemons into a bucket of warm water.
- Use this to mop floors or wipe countertops in your kitchen and bathrooms.
- Repeat every other day for a clean, pest home.
Bonus: it makes your home smell amazing!
7. Soapy Water Spray – Instant Cockroach Killer
Simple but effective, soapy water clogs the breathing pores (spiracles) of cockroaches, killing them almost instantly.
- Fill a spray bottle with water and add a few drops of liquid dish soap.
- Shake well and spray directly on roaches when spotted.
- Dispose of the dead ones properly and keep spraying entry points.
Myth vs. Fact: Cockroach Control

- Seal cracks in walls, tiles, and around doors/windows.
- Fix any water leaks under sinks or around plumbing.
- Empty trash daily and keep lids tightly closed.
- Store dry foods in airtight containers.
