Not only is peppermint oil a natural cockroach repellent—it's also toxic to roaches (and for the record, to bed bugs, too).
Roach Repellents
Peppermint oil, cedarwood oil, and cypress oil are essential oils that effectively keep cockroaches at bay. Additionally, these insects hate the smell of crushed bay leaves and steer clear of coffee grounds. If you want to try a natural way to kill them, combine powdered sugar and boric acid.
Peppermint oil repels most roaches, including American and German cockroaches. As a bonus, the oil will also kill these bugs. One study found that in just two weeks of use, the oil killed all of the roaches in an area.
Diluting a few drops of peppermint oil with water and spraying it on walls or on cotton balls that you place throughout your home could effectively repel roaches. You add 1 part vinegar to 2 parts water for a stronger solution.
Raid Ant & Roach Killer Insecticide Spray was found to be one of the most effective at killing cockroaches. A can is helpful for the times when you spot a roach in your home and you don't want to get too close. A roach spray should kill the bug almost instantly.
Not only is peppermint oil a natural cockroach repellent—it's also toxic to roaches (and for the record, to bed bugs, too).
Household bleach is commonly used as a cleaning agent and gives off a strong smell that cockroaches hate.
The smell of lemons repels cockroaches to a great extent, keeping them away from areas that reek of the fruit. Hence, it is advisable to mop floors with water that has a few lemon drops in it.
Does Cinnamon repel cockroaches? No, cinnamon doesn't repel cockroaches. But there're are other essential oils or spices that can work against cockroaches. You can use bay leaves, garlic, and catnip to reduce some amount of cockroach activity in your home.
Lavender. Cockroaches hate the smell of lavender, and that is good news for you. If you love to grow lavender in your yard and garden, you are more than halfway to a roach-free home.
Citrus Attack
It's been said through the decades that cockroaches detest citrus flavor. They don't. Cockroaches would find themselves perfectly at home inside anything from an orange peel to a citrus grove.
This alerts cockroaches of danger, food, and the location of their colony. Because these organs detect vibration, cockroaches hate the sound of clapping, doors slamming, and stomping.
It's a fact that cockroaches are afraid of humans and other mammals or animals that are bigger than them. They see us as predators and that fear triggers their instinct to scatter away. However, they dislike strong and distinctive scents such as citrus, peppermint, lavender and vinegar.
Eucalyptus oil has a strong scent that seems to have some success in repelling roaches. You can dilute it with water and spray areas you think cockroaches might have nested.
Aromatherapy or topical use of diluted essential peppermint oil can have significant benefits with little risk. But be aware that peppermint aromatherapy can be toxic to pets. Always consider children, pets, and pregnant women before using aromatherapy. If taken in very large doses, peppermint oil can be toxic.
Let your mint go to flower and it will attract bees, beneficial wasps, hoverflies (aphid eaters), and tachinid flies (parasitic on nasty bugs). The smell of the mint plant will also repel houseflies, cabbage moths, ants, aphids, squash bugs, fleas, mosquitoes, and even mice. Not a bad deal, if you ask me!
Why Do Flying Cockroaches Fly Toward You? If you think flying cockroaches are flying right toward you, they actually aren't. Most cockroach species aren't good "flyers," and what you take as them flying toward you is actually just them being startled and gliding uncontrollably in a certain direction.
Flies are the most common and dirtiest of the restaurant pests. These small bugs can carry billions of harmful microorganisms, including E. coli and Salmonella, which can lead to serious illnesses in humans.
Do Cockroaches Like the Cold? Generally, cockroaches don't like the cold one bit. They are cold-blooded arthropods that don't survive very well in either extremely cold or hot circumstances. They're always at whatever temperature their environment is and generally slow down with cooler temperatures.
Certainly, seeing a cockroach can elicit high-pitched screams from an unsuspecting homeowner late at night. However, the most common species, the American and German roaches, are generally acknowledged to be silent.
Myth #3: They can see me coming…
True: Why yes, they can. Cockroaches can see humans, and that is why they tend to run in fear when we are in their line of sight. The eye of the cockroach is like a compound lens, made of over 2,000 mini lenses that are photoreceptors and allow them to see in complete darkness.
Add some food like a small piece of meat or some sweet stuff like chocolate on the roach bait in the bowl. Keep the bowl near one of the hiding places of roaches. To cover all the hiding places, you'll need multiple bowls with sticky roach trap and food. The smell of the food will draw the roaches out.
This simple home remedy for infestations involves putting dryer sheets into the favorite hiding places of cockroaches. Dryer sheets contain linalool, a naturally occurring substance found in certain plants. While dryer sheets won't kill cockroaches, linalool can be a roach repellent.
Most dryer sheets contain the ingredient linalool, which can be found in plants like lavender, basil, and coriander, all of which naturally repel common garden pests. Similar studies found that this ingredient is also useful for repelling bugs like mites, weevils, beetles, and German cockroaches.
