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.  160  170  110  j}E  .(<<  :;g,’y~!,  - 18  days  ••1:i:;I@~:,.tt:i•’:}~{::(\~:i~:~L?.}.•{~:;\j:,/’.:t;~~~  ..... •• .....  100
