The short answer is yes; the scent of vinegar can help to keep cockroaches away. However, it is helpful to note that this is not a guaranteed solution, and you may still see cockroaches in your home even if you use vinegar. Therefore, we believe it's a great repellent but not an effective roach killer.
All About Vinegar
Unfortunately, it doesn't actually kill these problem insects. It's more of a cleaning tool than anything else, and it won't actually help eliminate your roach problem. It can, however, help deter roaches and get rid of germs in the kitchen when used as a cleaning agent.
You put it in the kitchen sinks and bathroom drains, etc. for the cockroaches to flee helter-skelter. White vinegar is a known cockroach repellent. To use it, mix equal amounts of water and vinegar and sprinkle on the area where the cockroaches come out.
The best way to keep cockroaches away permanently is to make the home less inviting. Make sure to keep the home clean, clean up food messes, take out trash at the end of the day, seal any cracks or gaps around windows, doors and the foundation, and fix any issue that might lead to high moisture content within the home.
You can spray a mixture of oregano oil and water on countertops and any nooks and crannies. Oregano has a strong, pungent odor that cockroaches can't stand. Since it's a safe oil to use around the kitchen, you can spray a mixture of oregano oil and water on countertops and any nooks and crannies they like to hide.
Boric acid Some people find this to be the best option to kill roaches. Boric acid can work too, the only downside is that sometimes roaches will go away as soon as they smell boric acid.
Pine-Sol and Fabuloso are strong, all-purpose household cleaners. Similar to bleach, these products kill roaches on contact. Some homeowners suggest spraying Pine-Sol around the outside of your house to keep cockroaches away.
Smells that roaches hate: a quickfire summary
Oregano, rosemary, mint, eucalyptus, lemongrass and catnip are great herby options. Citrus oils work brilliantly too.
Clean and Sanitize
You might have a clean home, but this first step is about more than just sweeping: you'll need to empty out cabinets, move furniture and vacuum everywhere. You should also throw out any opened, damaged or unsealed food that could have been contaminated by roaches.
Home remedies like diatomaceous earth, baking soda, boric acid, citrus, essential oils, and borax can be effective ways to get rid of roaches. If you want to take a more aggressive approach to eliminate roaches, glue traps, bait stations, and liquid roach deterrent concentrates are all excellent options.
If you are however living in a house with children or pets, vinegar will be the safer option to getting rid of cockroaches. All you will need to do is mix vinegar with water in a 70:30 ratio and spray it around your kitchen area. As cockroaches hate the smell of vinegar, this will help keep them away.
Bleach's Effect on Roaches
Taking a deep drink of household bleach would kill anything, roaches included. But the same strong odor that keeps people from taking a swig of bleach repels roaches as well. So though it could work, in reality, it will not. It is very difficult to kill an entire roach infestation yourself.
Spraying window cleaner directly onto small insects like ants or mosquitoes will kill them within a few moments. For cockroaches, window cleaner can make them temporarily unconscious so that you can squash them. This works on initial contact, but Windex will not continue to kill bugs after it has dried.
Good old-fashioned soap and water is a safe, reliable, and inexpensive method. Create a soapy water solution that you can spray with a bottle. It will only take about 2 – 3 sprays to kill any roaches, as the soapy solution will cover their breathing pores and suffocate them.
Cockroach predators include mammals, avians, amphibians and other reptiles. For example, hedgehogs will eat roaches. Joining the roach à la mode dinner party are geckos, skinks and other species of lizards, frogs, turtles, some types of birds and even rats and mice.
Sugar. Sugar is by far the most attractive substance to a cockroach. They love sugar and can smell it from anywhere. This means you'll want to keep your sugar containers, fruits, and other sweeteners sealed in air-tight containers that are up off the floor.
Two of the most common cockroach predators are toads and frogs! Both of these amphibians are known for eating insects like flies, but they also gladly welcome cockroaches.
Dryer Sheets: Mostly False
Linalool is an alcohol derived from plants, and it gives dryer sheets their distinctive scent. In sufficient concentrations, linalool can indeed be used as a pest repellant, but your average dryer sheet doesn't contain enough of it to actually work on roaches.
Pine Sol, like many household cleaners, such as bleach, is capable of killing a cockroach on contact. In the pest control world, we call these contact insecticides.
Roaches are attracted to similar things as any other pest: shelter, food, and water. Anything that makes these things more available and easy to access is going to contribute to a roach infestation.
One popular DIY method is to mix boric acid with equal parts powdered sugar as a lure. Apply as a fine layer under appliances, behind cabinets and along crevices. Roaches ingest the mixture and die within a few hours.
Lemon and lemongrass essential oils specifically will drive any cockroach away due to their strong scent of limonene, which smells like nothing else on earth! Add a couple of drops of citrus or peppermint essential oil to a few cotton balls, and lay them around where the roaches in your home congregate.
Sprinkle the diatomaceous earth around areas where roaches travel and frequent. The sharp particles of diatomaceous earth damage the waxy, protective exoskeleton of the roach, causing it to dehydrate and die, typically within 48 hours of contact.
