35% food grade hydrogen peroxide is available at amazon. That would be the first thing I would try. It can be diluted and mixed with clorox. There are also many herbal oils that are deadly to parasites. Also like any living creature they are sensitive to heat or cold so you can even do something as simple as dripping candle wax onto the skin where the parasites are. I once did that to get rid of a worm burrowing under my skin.
