Hmm, wine with insect repellent in it.... I'd pass on that one myself.
If you aren't already, then be sure to use brewers yeast of some kind for you beer/wine/mead/cider/zombie repellent. Bread yeast makes horrible brewed anything.
Pectin enzyme and a clarifier like bentonite or gelatin would be a good idea. There is a water soluble carbohydrate in practically all fruit called pectin. If it stays in the brew it will cloud it. Pectin enzyme breaks it into sugar. Bentonite is a pretty common clarifier for wine. It's got a strong negative charge, so other particulates in suspension are attracted to it. They start clumping together and end up heavy enough to fall out of suspension.
A couple of fermentors that seals well wouldn't be a terrible idea either. That should keep the fruit flies out. If you want to be extra paranoid about it, fill your airlock with vodka or some other strong spirit. With more then one fermentor you can move your brew off of the yeast cake in the bottom of the container. That will help with clearing, and get a lot of the yeast out of the brew. Yeast is nice for a wheat beer, but not much else that's fermented benefits from it in the brew after it's done.
If your process is as basic as it sounds, then there are a lot of ways you can improve things at this point.
