Boric Acid

This natural insecticide is a great way to kill cockroaches without putting your health at risk. Simply mix it with sugar or flour and sprinkle it in areas where cockroaches like to hide.

Essential Oils

Diatomaceous Earth

This powdery substance may sound strange, but it’s actually a powerful tool against cockroaches. Made from fossilized algae, diatomaceous earth damages the exoskeleton of the roach, leading to dehydration and death. Just be sure to wear gloves and a mask when handling it.


catnip is not just for feline friends. Dried catnip leaves contain nepetalactone, a natural insect repellent that is toxic to cockroaches. Crush the leaves and sprinkle them in areas where you’ve seen cockroaches.


Prevention is key when it comes to keeping cockroaches out of your home. Make sure to keep all surfaces clean and dry, store food in sealed containers, and fix any leaks or water damage as soon as possible.

By utilizing these natural remedies and maintaining a clean living space, you can say goodbye to cockroaches without putting your health or the environment at risk.

Bait Using Baking Soda and Sugar

Baking soda and sugar baiting is the answer to your prayers.

Baiting is a proven method for controlling cockroach infestations, and using baking soda and sugar bait is one of the simplest and most natural methods. This recipe works by producing carbon dioxide gas in the cockroach’s stomach, causing fatal bloating. The sugar in the mixture attracts the cockroaches while the baking soda kills them.

Making this bait is easy-peasy. Mix equal parts of baking soda and sugar in a bowl until they are well combined. After mixing, place small amounts of the mixture in strategic locations where you’ve seen cockroach activity, such as near baseboards or behind appliances. Replace the mixture every three days for maximum effectiveness.

It’s important to note that this method works best in areas with low humidity levels. In high humidity areas, the mixture can become damp and lose its effectiveness. Also, be cautious when placing bait in areas accessible to children or pets. To prevent accidental ingestion, place the mixture in secure containers or areas that are not accessible to them.

Using baking soda and sugar bait is an excellent natural solution for getting rid of Australian cockroaches. Not only is it effective, but it’s also safe for your family and pets.

Diatomaceous Earth: A Powerful Pest Killer

Look no further than diatomaceous earth (DE), a natural and potent solution to your pest problems.

DE is composed of fossilized diatoms, microscopic aquatic organisms. This powder-like substance works by dehydrating the exoskeleton of cockroaches, ultimately leading to their demise. It’s an effective and natural way to rid your home of these unwanted pests.

To use DE, simply sprinkle a thin layer in areas where cockroaches are commonly found, such as around baseboards, under appliances, and in cracks and crevices. Keep in mind that it’s essential to wear a mask when applying DE as it can be harmful if inhaled.

It’s crucial to note that not all DE products are created equal. Look for food-grade DE, which is safe for humans and pets to be around. With this product, you can feel confident that you’re not putting anyone at risk while eliminating the pests.

Using DE as a cockroach killer may take some time to see results, as cockroaches can survive for several days without food or water.

However, persistence is key, and with consistent application, you’ll see a noticeable reduction in cockroach activity.

Essential Oils to Repel Cockroaches

These oils contain potent compounds that can deter cockroaches from entering your space and keep them away for good.

Peppermint oil is a powerful insecticide and repellent that disrupts the cockroach’s sense of smell, making it difficult for them to locate food and shelter. Mix a few drops of peppermint oil with water in a spray bottle and apply it around cockroach hotspots in your home, such as under sinks, behind appliances, and in dark corners. The refreshing scent of peppermint will also leave your home smelling fresh and clean.

Eucalyptus oil is another essential oil that is highly effective at repelling Australian cockroaches. Its strong scent is particularly effective at keeping these pests at bay. Mix a few drops of eucalyptus oil with water in a spray bottle and apply it around your home to create an invisible barrier that cockroaches won’t want to cross.

Tea tree oil is another natural insecticide that is toxic to cockroaches. This potent oil can be mixed with water in a spray bottle and applied to areas where cockroaches are known to frequent. Not only will it repel these pests, but it will also help to kill any lingering ones that may be hiding in your home.

Finally, lavender oil has a calming effect on insects and can be used to repel Australian cockroaches. The soothing scent of lavender will help keep these pests away while also creating a relaxing atmosphere in your home. Mix a few drops of lavender oil with water in a spray bottle and apply it around your home for best results.

Using essential oils in combination with other natural pest control methods can help keep your home free from unwanted pests without the use of harmful chemicals.

Sealing Cracks and Crevices in Your Home

There is a natural and effective solution: sealing cracks and crevices.

These pests are notorious for finding their way into even the smallest gaps in doors, windows, and walls. By sealing off these entry points, you can prevent cockroaches from entering your home and make it harder for them to hide once they’re inside.

To get started, conduct a thorough inspection of your home for any potential entry points. Check around doors and windows, as well as areas where pipes or electrical wiring enter your home. Don’t forget to examine walls or floors in damp or humid areas.

Once you’ve identified the entry points, use an appropriate sealant like silicone caulk or expanding foam to fill the gaps. Follow the manufacturer’s instructions carefully to ensure a secure seal.

While sealing cracks and crevices is important, maintaining a clean and tidy home is also crucial. Cockroaches are attracted to food scraps and debris, so always clean up any spills or crumbs promptly. Store food in airtight containers and empty your trash regularly.

By following these steps, you can effectively get rid of Australian cockroaches without relying on harmful chemicals or pesticides.

Keeping Your Home Clean and Clutter-Free

These pesky critters can be a real nuisance, but fear not, one of the most important steps to keep them at bay is to maintain a clean and clutter-free environment.

Cockroaches are attracted to food and moisture, making it crucial to keep your living space as dry and clean as possible. Start by regularly cleaning up spills or crumbs in your kitchen and dining areas. Wipe down counters, sweep floors, and store any food in airtight containers. Taking out the trash regularly and keeping garbage cans clean can also make a significant difference in keeping these unwanted visitors out of your home.

Don’t forget about your bathroom. Cockroaches love damp environments, so it’s essential to wipe down surfaces after use, fix any leaks, and use a dehumidifier if necessary. And let’s not neglect those cluttered areas – cockroaches are notorious for hiding in piles of stuff. Declutter your home regularly by getting rid of excess items you don’t need or use, especially in areas like basements, attics, and closets.

Finally, take a look around your home and seal any cracks or gaps that could serve as entry points for cockroaches. Check around doors, windows, pipes, and vents for any openings that need to be filled.

By keeping your home clean and clutter-free, you’ll not only reduce the likelihood of an Australian cockroach infestation but also create a healthier living environment for yourself and your family.

Professional Extermination Services

When it comes to pesky pests like Australian cockroaches, sometimes it’s necessary to call in the big guns – professional extermination services. These services are designed to effectively eliminate even the most severe infestations, using a variety of methods such as baits, traps, and insecticides.

However, before hiring an exterminator, it’s important to do your due diligence and choose a reputable company with a strong track record. This means checking reviews, asking for referrals from trusted sources, and ensuring the company is licensed and insured for your peace of mind.

During the treatment process, it’s crucial to follow the exterminator’s instructions to a tee. This may involve removing potential food or water sources for the cockroaches, sealing up any cracks or crevices where they might be hiding, and keeping children and pets away from treated areas. By doing so, you’ll help ensure the most effective eradication possible.

While professional extermination services can be expensive and require multiple treatments for complete elimination, sometimes they’re the only option for severe infestations. However, it’s always best to try natural methods first and take preventative measures to avoid future infestations. This can include keeping a clean home, sealing up gaps in walls or floors, and properly storing food and waste.

Preventative Measures for Future Infestations

Look no further because we’ve got you covered with some natural and effective measures. Here are six simple steps to keep these creepy crawlers out of your home for good:

  • Firstly, cleanliness is key. Regularly clean your home, particularly the kitchen and dining areas, as they are the perfect breeding ground for cockroaches. Be sure to wipe down counters, sweep floors, and wash dishes immediately after use.

  • Thirdly, seal entry points. Cockroaches can squeeze through even the smallest cracks or gaps in walls, windows, doors, pipes, and other areas. Seal these entry points with caulk or weather stripping to prevent these pests from entering your home.
  • Fourthly, remove clutter. Cockroaches love clutter as it provides shelter for them. Declutter your home by getting rid of old boxes and newspapers.
  • Fifthly, use natural repellents such as essential oils like peppermint, lavender, and eucalyptus. You can also sprinkle boric acid powder around entry points and hidden areas to repel them.
  • Lastly, maintain proper humidity levels. Cockroaches thrive in humid environments so keeping the humidity levels in your home below 50% is necessary. You can achieve this by using dehumidifiers or air conditioners.

By following these preventative measures, you can ensure that your home remains cockroach-free in the future. Remember that prevention is always better than cure when it comes to pest control.
