Keep mosquitoes and biting flies from crashing your patio party with appropriately-themed wine bottle tiki torches. Fill a few empty glass bottles one- to two-thirds full with sand, small stones, or marbles. Then pour citronella-scented lamp oil in up to the neck of each bottle—this will give you several hours of burn time. Drill holes through the corks and thread a piece of cotton rope through it, with enough length to reach to the sand or stones at the bottom and an inch exposed above the cork. As soon as the wick soaks up the oil, light and enjoy a bug-free backyard.
