I need to know how to keep moths and other flying bugs off my cake. Here are the conditions: I am getting married/having reception in May, in Louisiana, at night, about 4 feet from a lake. I know we are going to need lights to see but how do I keep bugs off my beautiful buttercream icing cake? I am using battery powered christmas lights everywhere and candles for the lighting. Would a makeshift tent type thing work? I was thinking we could make a frame out of PVC pipe (painted of course) with tulle hanging off of it, to cover it and keep the big bugs out. Is this good enough or is there something else I could do?
