How to Get Rid of Roaches with Home Remedies
As roaches multiply quickly, you have to take measures to eliminate them as soon as possible. Here are some of the simple ways on how to get rid of roaches in your home.
1. Borax and Sugar
When it comes to preventing insects and controlling the growth of cockroaches, borax is an effective option. It dehydrates these pests and leads them to their demise by damaging their digestive system.
You can enhance the effectiveness of borax by mixing it with sugar. This allows you to lure roaches as they are attracted to sugar.
Here’s how to get rid of roaches with borax:
- Mix equal parts of borax and sugar in a cup.
- Sprinkle this mixture in areas where you often see roaches.
- Leave this bait overnight and repeat the application as often as necessary. When they walk through it, roaches will ingest it later and borax powder will kill them.
- Discard the dead roaches immediately.
- Follow this treatment until you no longer see roaches around your home.
Note: Keep the mixture away from small children and pets.
2. Fabric Softener Spray
One of the simplest ways to kill roaches is by spraying fabric softener on them. These creatures breathe through their skin, so a soapy solution will stop them from breathing.
This technique will suffocate roaches while disinfecting the area that they made contact with. To do this method, you will need a spray bottle, water, and natural fabric softener.
- Mix ½ cup of water with ¾ cup of fabric conditioner.
- Pour the mixture into a spray bottle and shake. Make sure that the solution has thick consistency as your aim is to keep the critters from breathing.
- Use the solution directly on roaches when you see them.
If you see a roach on the floor or counter, you can use this spray rather than stepping on them. The thick spray will suffocate them, making it one of the best ways on how to get rid of roaches in the house.
3. Diatomaceous Earth
Another effective method on how to get rid of roaches without an exterminator is the use of food-grade diatomaceous earth. It is also useful for killing termites, ants, bugs, and fleas.
Diatomaceous earth is a great choice for eliminating roaches in hidden areas, such as behind appliances and top of cabinets. When they directly come in contact, the small and sharp particles of diatomaceous earth will penetrate their waxy exoskeleton.
- Apply a thin layer of food-grade diatomaceous earth on infested and dry areas.
- Reapply once a day to kill all roaches in your home.
Although DE feels like a powder to humans, it feels like thorns for insects.
Note: Before handling diatomaceous earth, always wear rubber gloves and mask. Do not use it on damp areas as it needs to be dry to be effective.
4. Lemon Juice or Lemon Peels
The citrus scent of lemon is often linked to a clean home as this fruit is often used as an ingredient in many household cleaning products. There is no doubt that lemon juice is powerful when it comes to repelling roaches and other insects.
- Grind up some lemon peels and put them on the areas where roaches are always present.
- Alternatively, add enough lemon juice in a spray bottle and spray it directly on roaches. Use it on hard-to-reach areas of your home.
- You can also add lemon juice in a bucket and add enough water. Make sure that the juice is not too diluted. Use towels or rags to clean all countertops and floor.
If fresh lemons are not available, you can purchase 100% lemon juice.
5. Eliminate Food Sources
One of the most effective ways on how to get rid of roaches for good is by eliminating their food sources. These creatures will keep on returning as long as they can take scraps and spills.
- Always clean kitchen appliances. These critters can live off spills and grease behind or under your appliances. Clean behind and under the refrigerator, toaster, dishwasher, microwave, stove, and sink.
- Hide food in sealed containers. Consider storing your food in glass or hard plastic containers. Do not leave food on the countertop as these can get contaminated by roaches.
- Take the trash out. Do not let garbage bags sit for too long. Also, use a trash can with a tight lid.
- Sweep or vacuum the floor regularly. To keep your home roach free, you will need to keep your house clean at all times. Use a vacuum cleaner to pick up roach feces, egg sacs, and body parts as these can attract other roaches.
- Clean kitchen cabinets. Food spills and crumbs offer a buffet for roaches and ants.

6. Roach Traps
You can use store-bought traps like Cockroach Traps by Killer Green or make a homemade bait to lure them in.
- Take two to three large jars.
- Apply a thick layer of petroleum jelly on the insides of the jars. This will prevent roaches from escaping.
- Add crumbs of food, wet coffee grounds or malt beverage to serve as bait.
- Place the jars near the infested areas.
- Once you see enough roaches trapped in the jar, kill them with fabric conditioner or other powerful insecticides.
You can also take the jars to a pest control team or throw them out in the wild.
This is an effective solution to get rid of adult roaches. You will need to combine this method with other remedies to kill the eggs and destroy their nests.
7. Seal up Holes and Cracks
To keep roaches and other insects from entering your premises, you will need to seal all holes and cracks. Eliminating their breeding and hiding places will force them to leave your home.
- Seal up cracks and holes inside your kitchen, in the baseboards, walls and counter-tops using a caulking gun and caulk.
- Fill the cracks on both sides of the window moldings, door, and floor. Do not forget the openings around pipes in kitchen and bathroom.
This may take up some time but it is worth the effort. It is one of the best ways to get rid of roaches in apartment, especially if you have neighbors who do not meet the same standards of sanitation as you do.
8. Cut off Water Source
If you suspect that your house is infested with roaches, these insects must have a water source. Depending on their size, they can survive for thirty days without food, but they cannot go on for a week without water.
- Check all pipes and faucets. Find all leaks and fix them.
- Do not overwater your indoor plants and avoid letting water stand in your sink.
- Check all toilets, shower heads, and hoses for leaks.
Once you cut off their water sources, roaches will be more interested in eating your baits.
9. Baking Soda and Sugar
Like boric acid, baking soda will also damage the digestive system of roaches and kill them eventually. You can make sure that they will eat this bait by mixing it with an equal amount of sugar.
- Mix equal parts of sugar with baking soda.
- Sprinkle them near infested areas, such as behind kitchen cabinets, under the sink, and around pipes, counter tops.
- Repeat the application of the mixture once or twice a day to kill the roaches.
Since baking soda and sugar are merely and not pesticides, they won’t get rid of roaches as quickly as chemicals. This is one of the safest methods on how to get rid of roaches naturally for your family and pets.
10. De-Clutter Your Apartment
You can keep roaches, termites and other insects from entering your premises by de-cluttering your home. Follow these simple tips on how to get rid of roaches in an apartment permanently:
- Dispose of waste newspapers, cardboard, and other unused materials where roaches can create an army.
- Store leftover food in containers with airtight lid to prevent roaches from scavenging around your home.
- Use lemon juice for cleansing oven, refrigerator and other food processing devices.
- Pack other items that you do not use often and place them in bags or cabinets. This will provide you more space while keeping your home free from roaches and termites.
- Remove all trash cans and wood piles from your yard.

12. Kaffir Lime Essential Oil
A tropical fruit that is native to Thailand, Indonesia, Philippines, and other parts of Asia, kaffir lime are often used for repelling insects. The limonene and citronellol found in this fruit are unappealing to roaches.

13. Neem Oil
Neem powder or oil is a better alternative to synthetic insect repellants. It is economically cheaper and less toxic to human, animals and plants.
The highly volatile components in neem act as a natural insect deterrent. It was also found that neem is one of the best plants that can keep pests away.
- Add one tablespoon of neem oil in a medium-sized spray bottle.

15. Cedar Oil
Cedar oil is effective in controlling different insects, such as roaches, mosquitoes, ticks, moths and fleas. It acts to leach moisture from pests and leave them dehydrated.
This oil alkalizes the body serums of insects and emulsifies their body fats. It also causes severe respiratory irritation and causes them to avoid breathing.
- Mix cedar essential oil with rubbing alcohol. Pour the mixture into a spray bottle and use it around your home.
- Alternatively, you can place some cedar chips on areas where you often see roaches, such as bathroom cabinets, under the sink, and inside the kitchen.
Cedar oil dissolves pests in early stages like eggs and larvae. It also disintegrates the exoskeletons of adult ones too.
16. Pepper, Onion, and Garlic

- Repeat the process every five days to drive roaches out and prevent them from returning.
You can also place some bay leaves near containers of rice, flour, and other goods. Consider taping some leaves inside shelves and cupboards.

Many insecticide products contain pyrethrum. It is a daisy flower native to northern Europe and Asia. Also known as chrysanthemum, the toxins produced by these flowers can kill insects effectively.
