I'm finishing up a base when I noticed a bad night mare. I have bacteria growing and I would like to know if there is something out there that I can get from Home Depot or any hardware store real fast like. I tried a new concoction using paper mache, Vermiculite, plaster paris and water. I can know see the water is probubly the culprit here. I just sealed the dirt and leaves with a calk and water mixture when I noticed the bacteria growing. I need something that I can spray directly on this habitat to kill it. I will try to post a pic, but not sure how that will turn out. Any help is needed real fast before further growth. Thanks very much.
