Cockroaches: Several of these fragrant plants will help discourage cockroaches from entering your home, including chrysanthemums, catnip, peppermint, and lavender. Fleas and bedbugs: These itchy insects hate lemongrass, lavender, citronella plants, catnip, and chrysanthemums.
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.
Chrysanthemums
This flower is popular for vibrant shades and a strong scent that helps deter roaches, mites, fleas, bugs, and ticks. Its bloom has Pyrethrins, which is a natural insect repellant.
Tea Tree Oil. Many homeowners report that roaches don't like tea tree oil. You can combine 1 part vinegar and 4 parts water with a few drops of tea tree oil and apply the mixture with a spray bottle to deter cockroaches from specific areas.
Smells that roaches hate: a quickfire summary
Oregano, rosemary, mint, eucalyptus, lemongrass and catnip are great herby options. Citrus oils work brilliantly too. And surprisingly, lower concentrations – 2.5 parts per hundred – seem to work best as deterrents. Just don't bother with lavender.
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.
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.
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.
Mint or eucalyptus - Roaches hate the smell of mint too. You can use this in many different ways. From placing these plants in the corners of your house or using the eucalyptus' essential oil as a spray. Clove oil - This works best with other essential oils like peppermint or citrus.
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.
You can use lavender oil inside your home to chase existing roaches away and stop new ones from coming in. Lavender essential oils work well for this purpose; you can dilute the oil and place it in a spray bottle, then spray surfaces where cockroaches have been a problem.
The best way to get rid of roaches fast is to sanitize your home, eliminate hiding spots and stagnant water, store food in airtight containers, and use glue strips, bait, boric acid, or liquid concentrates.
Sprinkle boric acid in areas the roaches frequent; when they walk through it, it sticks to them. They later ingest the boric acid, which then kills them. When using boric acid, be sure to limit your exposure; don't place it anywhere that children or pets might find it, as it's toxic when ingested.
Crumbs and Dropped Food
Speaking of food spills, these can be another top attraction for cockroaches. If there are any crumbs or spilled drops of food on your kitchen floor at the end of the night, you can bet that the roaches will feed off these once you've gone to bed.
Anything from food left on bookbinders, small pieces of trash, soap containers, and more will attract roaches. ⦁ Hidden Areas- if there are any areas around your home that are forgotten like old cupboards or small crevices in your walls, these will attract cockroaches.
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.
It sounds unbelievable, but is it true? Can Irish Spring soap repel roaches? No, Irish Spring will not repel roaches. Roaches are neither attracted to nor repelled by the smell of Irish Spring or any other soap, and only purpose-designed insecticides or natural materials with known insecticidal qualities will work.
As such, some websites suggest placing coffee grounds around your home to keep roaches away. However, in a 2020 study published in the International Journal of Science and Healthcare Research, researchers tested this out and found that coffee grounds were not very effective at repelling cockroaches.
You will have to reapply pretty frequently so the fragrance doesn't wear off. Since cockroaches are nocturnal, your best bet is to reapply each night before you go to bed. That way, when the roaches are most active, your peppermint oil repellent is at its strongest.
