Hot summer weather also means one more thing: mosquitoes. Instead of using chemical sprays to keep pesky bugs away, reach for something in your medicine cabinet instead. Natural mouthwashes from the supermarket or natural foods store are usually made with food-grade alcohol and eucalyptus oil to freshen breath. By transferring this same mixture into a spray bottle, you can keep mosquitoes at bay. Spray your skin, the table and anything else around with natural mouthwash. The alcohol will dry out mosquitoes and the eucalyptus oil is powerful enough to act as a deterrent. Plus, it all smells nice!
