## (57) ABSTRACT 

The current invention involves compositions methods and apparatus for killing various soft-bodied animals of interest (more specifically, Coqui frogs and Coqui frog eggs are tar› geted) with a low pH adjusted pesticide. The method and apparatus involves contacting the soft-bodied animal ofinter› est with the low pH adjusted pesticide, wherein the pesticide is a propionic acid composition, a citric acid composition, an Acidic Calcium Sulfate (ACS) composition, or combination thereof. The preferred pesticide composition has a working concentration that is less than about 15% (w/v), and a pH less than about pH 2.5, which has a lethal effect on Coqui frogs, but is less phytotoxic than higher concentration pesticides. The method and apparatus includes spraying any of the pH adjusted pesticides thoroughly an area inhabited by the soft› bodied animals of interest, which includes the under brush, under bushes, and typically any hiding places. An apparatus for spraying potted plants is disclosed. On a large scale, the method and apparatus contemplates filling various types of industrial spraying equipment with the pesticide and saturat› ing entire pest inhabited areas.
