Abstract
The current invention involves compositions and methods for killing various soft-bodied animals of interest (more specifically, Coqui frogs and Coqui frog eggs are targeted) with a low pH adjusted pesticide. The method involves contacting the soft-bodied animal of interest 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 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. On a large scale, the method contemplates filling various types of industrial spraying equipment with the pesticide and saturating entire pest inhabited areas.
