Clinton Kelly sure does give great advice. But if you don't have the materials for this trick, there are a few other ways to keep bugs away from your snacks. A portable fan gives a nice breeze and can keep pests away if you set it up facing the food and turn it on. The wind from the fan makes it hard for bugs to get to your table. You can also use citronella candles or tiki torches to keep bugs away. If you've got two tables a few feet away from each other, place your food on one table and place something sweet, like sugar water, on the other. The bugs will be drawn to the sweet table and leave the food alone. You can also "float" your table by placing the legs in water-filled containers to keep ants from crawling up them.
