Mix listerine original with household vinegar and spray it all over the body to prevent mosquito bites. -- I don't know about the body but I'll try it around the campsite and see if it keeps them away.
Make travel coffee bags out of coffee filters and dental floss. Place a scoop of coffee grounds into a coffee filter and tie it up with dental floss. When you’re ready to brew, just make it like you would make tea in a teabag! Good for camping.
