Mosquitoes are pesky and annoying. The little bloodsuckers can ruin a relaxing night outdoors. You will find yourself busy swatting them away instead of enjoying the time with friends and family.
Coffee grounds are an unusual solution to this annoying little problem. According to the EPA, coffee grounds are a safe and effective way to repel mosquitoes and other troublesome insects. A study also showed that coffee grounds and caffeine could kill larvae by preventing the development of adult mosquitoes. The insects were not able to build a resistance to coffee.
To burn coffee grounds to use as a repellent, start by grabbing your used grounds and placing them in a bowl covered in foil. Once the grounds have dried, burn them like incense. It is best to choose a spot upwind of your location, and you can add fresh bay leaves to the fire for extra repellent.
This is a cheap and effective way to prevent those bothersome insects from ruining your night.
I shudder when I think of how many grounds I've thrown away, not realizing that they could be used for insect repellent.
Coffee in the kitchen once more. Be sure to help me save the grounds...OK?
