Summer is one of the most wonderful times of the year.
It would be even better if it weren’t for all the mosquitoes and other pests that wake up with the change in season.
Commercial bug repellents are costly, toxic, and don’t always work as well as they should. They also have serious side effects including:
- Breathing difficulty
- Loss of alertness
- Upset stomach
- Nausea and vomiting
- Insomnia and mood changes
- Hives or mild skin redness and irritation on area sprayed
- Blistering, burns, and permanent scars
- Burning and redness of the eyes, nose, and throat
An Odd Natural Trick
Forget the citronella and DEET, and grab your morning coffee!
Mosquitoes, like many other bugs, have a large quantity of distinct odorant receptors (2). This makes them sensitive to certain strong smells, like the smell of smoke.
In fact, one of the best ways to keep mosquitoes away is to burn coffee grounds, which emit a very strong scent and produce a lot of smoke.
You can use fresh grounds or bone-dry used grounds. All you have to do is place the grounds in a bit of aluminum paper or an aluminum baking tray and burn it as you would incense.
Since loose grounds can fly in the wind and start a fire, it’s best to slightly moisten the coffee and to pack two tablespoons of the mixture into a cupcake mold, leaving it to dry for few days before use. For stubborn mosquitoes, add a few bay leaves into the mix
Coffee grounds will keep bugs away, so feel free to burn it on your porch or in a well-ventilated area of your home, but do not use it near your garden as it can deter pollinators like bees and wasps. If possible, let the smoke flow towards you for best results. Place as many burning grounds around you as you need.
The odor and smoke emitted also works as a repellent for ants, slugs, and snails (3).
