Does Mouthwash Deter Mosquitoes?

Q. To keep your picnic area free of insects, put Listerine in a spray bottle and spray the table and chairs where you are enjoying the outside. You will be bug-free for a few hours, if not days.
It doesn’t hurt the environment or you and your pets. It’s also inexpensive.
A. Others have also recommended Listerine (or its house brand counterpart) as a way of discouraging insect invaders. Perhaps the herbal ingredients (eucalyptol, menthol, thymol and methyl salicylate) that give amber Listerine its distinctive aroma also repel bugs.
There are certainly many products that contain DEET, but some people would prefer to avoid this repellent. More natural options that are available commercially include picaridin and oil of lemon eucalyptus. Here’s a link to many other creative ways to discourage bugs from attending the picnic and feasting on you.
