Finding roaches in your home can be unsettling, to say the least. Whether you’re dealing with one or multiple, the presence of these pests is frustrating and can make your living space feel unclean and unsafe. If you’re searching for ways to get rid of roaches quickly, you’re not alone. The good news is, there are effective DIY solutions that can help eliminate these unwelcome guests fast. In this guide, we’ll explore how to get rid of roaches overnight with simple, budget-friendly DIY methods to help you enjoy a pest-free home.
Why Roaches Are So Hard to Get Rid of
Before diving into DIY solutions, it’s helpful to understand why cockroaches are such a persistent problem. Roaches are highly resilient creatures that can survive without food for weeks, endure extreme temperatures, and withstand many common pesticides. In addition, they are nocturnal and adept at hiding in small cracks and crevices, making them difficult to detect until an infestation has grown.
Not only are roaches a nuisance, but they can also pose health risks. They carry bacteria that can contaminate food, spread germs, and trigger allergic reactions or asthma attacks. Roaches are typically drawn to warmth, moisture, and food—conditions that may exist in even the cleanest of homes.
Common causes of infestations include:
- Food sources: Crumbs, spills, and food left out overnight provide easy access to food for roaches.
- Water sources: Leaky faucets, damp surfaces, or standing water attract roaches.
- Entry points: Small cracks, gaps, or open windows give roaches easy access into your home.
Now that you understand why roaches are so difficult to eradicate, let’s focus on some simple DIY methods to get rid of them fast.
20 Proven DIY Methods to Get Rid of Roaches Overnight
Dealing with a roach infestation doesn’t have to take weeks or require expensive treatments. Below are 20 practical DIY solutions that can help you eliminate roaches overnight.
Step 1: Clean Your Space Thoroughly
The first step in any pest control method is to eliminate what attracts roaches in the first place. A clean environment will help your DIY remedies work more effectively.
- Clear clutter: Roaches love to hide in piles of paper, cardboard, and unused items. Start by decluttering your living space.
- Wipe down surfaces: Clean countertops, tables, and floors thoroughly with a disinfectant.
- Vacuum and mop: Pay attention to corners, under furniture, and behind appliances, as these are prime hiding spots.
- Seal food: Store all food in airtight containers and avoid leaving pet food out overnight.
A clean home will reduce the chances of a recurring roach problem.
Step 2: Use Boric Acid
Boric acid is one of the most effective and accessible DIY roach killers. When roaches ingest it, it destroys their digestive systems.
Here’s how to use it:
-
- Mix: Combine equal parts of boric acid, sugar, and flour to create a bait. The sugar attracts roaches, and the boric acid kills them once ingested.
- Apply: Sprinkle the mixture in high-traffic areas such as behind appliances, under sinks, and along baseboards.
- Important: Keep boric acid dry, as it loses its potency when wet.
Caution: Keep boric acid away from pets and small children.
Step 3: Try Baking Soda and Sugar
A safer alternative to boric acid is a combination of baking soda and sugar. Roaches are attracted to sugar, but when they eat the baking soda, it reacts in their digestive system and kills them.
- Mix: Combine equal parts of baking soda and sugar.
- Place: Put small amounts of the mixture in bottle caps or shallow dishes and place them in areas where roaches are active.
- Check regularly: Refill the traps as needed.
Step 4: Use Diatomaceous Earth
Food-grade diatomaceous earth is another natural substance that can help get rid of roaches. It’s a fine powder that dehydrates and kills roaches on contact.
- Apply: Lightly dust diatomaceous earth in areas where you’ve seen roaches, especially cracks and crevices.
- Reapply: Make sure to reapply every few days for continued effectiveness.
Pro Tip: Wear a mask when applying diatomaceous earth to avoid inhaling fine particles.
Step 5: Set Up Traps
Traps are a quick and easy way to reduce roach numbers overnight.
- Duct tape trap: Lay a piece of duct tape sticky-side up in areas where you’ve seen roaches. Add a small piece of food (like a cracker) in the center to lure them. Check the trap in the morning and dispose of any roaches caught.
- Jar trap: Smear petroleum jelly around the rim of a jar to make it slippery. Place food inside the jar, such as a banana peel or piece of bread. Roaches will crawl in but won’t be able to escape.
Step 6: Use Essential Oils as a Deterrent
Essential oils won’t kill roaches, but they can work as a repellent to discourage them from entering your home.
- Peppermint oil: Mix 10-15 drops with water in a spray bottle and apply it to entry points.
- Lavender oil: Roaches dislike its strong scent.
- Tea tree oil: Combine a few drops with vinegar and use it as a cleaning spray.
Essential oils can help reduce roach activity, particularly around entry points.
Step 7: Seal Entry Points
Roaches are excellent at sneaking in through tiny gaps. By sealing these entry points, you can make your home less inviting to them.
- Caulk cracks: Seal up gaps in walls, baseboards, and ceilings with caulk.
- Door sweeps: Install door sweeps under exterior doors to prevent roaches from entering.
- Vent covers: Cover vents with fine mesh to keep roaches from slipping through.
Step 8: Use a Homemade Spray
You can create a natural spray that kills roaches on contact. This simple recipe is effective for getting rid of visible roaches.
- Mix: Combine equal parts water and white vinegar in a spray bottle. Add a few drops of dish soap.
- Spray: Apply the solution directly to roaches when you see them.
For a stronger spray, you can add a small amount of rubbing alcohol.
Step 9: Utilize Catnip
Catnip contains a compound called nepetalactone that roaches find repellent.
- Boil catnip: Boil some catnip leaves in water to make a concentrated solution.
- Cool and spray: Once cooled, pour the mixture into a spray bottle and apply it to areas where roaches are active.
Step 10: Use Bay Leaves
Bay leaves act as a natural roach repellent due to their strong scent.
- Crush leaves: Crush fresh or dried bay leaves into a powder.
- Sprinkle: Sprinkle the powder in areas where roaches are likely to travel, such as behind appliances or near entry points.
Step 11: Coffee Grounds Trap
Used coffee grounds attract roaches and can be used to trap them.
- Prepare trap: Fill small containers with water and add a spoonful of used coffee grounds.
- Place traps: Set them in areas where you’ve seen roaches.
- Dispose of roaches: Roaches attracted to the coffee grounds will fall into the water and drown.
Step 12: Lemon Water Spray
Lemon juice has natural acidic properties that roaches dislike.
- Mix: Squeeze fresh lemon juice into a spray bottle and fill with water.
- Spray: Apply this mixture to cracks, crevices, and corners where roaches are active.
Step 13: Saltwater Treatment
Saltwater can help kill roaches by drying out their bodies.
- Mix: Stir a generous amount of salt into warm water.
- Spray: Spray the saltwater solution in areas where roaches are spotted.
Step 14: Use Clove Powder
Clove powder has a strong scent that roaches can’t tolerate.
- Sprinkle: Liberally apply clove powder in areas where roaches tend to hide.
- Vacuum: Vacuum up the powder after a few days and reapply if necessary.
Step 15: Place Onion and Borax Mixture
This combination of onion and borax is a powerful bait for killing roaches.
- Prepare bait: Chop onions finely and mix them with borax powder.
- Place traps: Set out shallow dishes of this mixture in roach-prone areas.
Step 16: Light Deterrent
Since roaches are nocturnal creatures, keeping lights on can discourage them from coming out.
- Install LED nightlights in kitchens, bathrooms, and other areas where roaches are common.
- Keep lights on overnight to discourage roaches from venturing out.
Step 17: Soap and Water Spray
Dish soap can suffocate roaches when sprayed directly on them.
- Mix: Combine a tablespoon of dish soap with water in a spray bottle.
- Spray: Apply the solution directly to roaches to kill them on contact.
Step 18: Freeze Infested Items
Freezing infested items like books or electronics can help eliminate roaches hiding inside.
- Seal items: Place suspected items in plastic bags.
- Freeze: Leave the bags in the freezer for 24-48 hours, then clean the items thoroughly.
Step 19: Use Garlic Spray
Garlic’s strong odor can help keep roaches away.
- Prepare spray: Crush garlic cloves and mix them with water. Let it sit for a few hours to infuse.
- Spray: Apply the garlic solution to areas where roaches are likely to be.
Step 20: Apply Petroleum Jelly
Petroleum jelly can trap roaches when used in a bait setup.
- Prepare trap: Coat the inside rim of a shallow container with petroleum jelly.
- Add bait: Place food like breadcrumbs or fruit peels in the center.
- Check in the morning: Roaches attracted to the bait will become trapped in the jelly.
Additional Tips to Prevent Roaches
Once you’ve eliminated the immediate problem, here are a few steps to keep roaches from returning:
- Take out the trash daily and keep trash cans sealed.
- Fix leaky faucets and pipes to eliminate water sources.
- Pour boiling water down drains weekly to flush out hidden roaches.
- Vacuum regularly and maintain cleanliness in all areas.
