Bacillus Thuringensis is a bacterium that produces toxins, which are deadly to mosquito larvae. For this reason, it is often used as a 'biological control agent' during the early spring, when mosquito larvae begin infesting puddles and ponds. The bacteria shown here are from store-bought tablets. When these tablets make contact with water, the bacteria activate and begin to produce toxins.
