NOVELTY - Acidic aqueous pesticide composition comprises an organic acid solution, which is present at below 16 wt./vol.% of aqueous pesticide composition, where a pH for the acidic aqueous pesticide is below 3. The organic acid is a citric acid and/or a propionic acid.    USE - The acidic aqueous pesticide composition is useful for killing a soft-bodied animal including a coqui frog, coqui frog egg, tree frog, cane toad, slug, nettle, caterpillar, nematode, an aphid, spider mite, fruit fly larva, Varroa mite and/or other soft bodied insects that are usually regarded as pests (all claimed). Test details are described but no results given.    ADVANTAGE - The acidic aqueous pesticide composition: has a lethal effect on coqui frogs; is less phytotoxic on plants than higher concentration pesticides; and is cost effective and environment friendly.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) killing a soft-bodied animal with an acidic pesticide composition, comprising: locating the soft-bodied animal or locating an area where the soft-bodied animal resides; and contacting the soft-bodied animal with the acidic pesticide composition, where the acidic pesticide composition comprises an acidic calcium sulfate (ACS) solution present at below 20 wt./vol.%, the acidic pesticide composition has a pH of 0.8-2.5, and the acidic pesticide composition is a liquid or a solid form;    (2) killing a soft-bodied animal with an acidic aqueous pesticide composition, comprising: locating the soft-bodied animal or locating an area where the soft-bodied animal resides; and contacting the soft-bodied animal with the acidic aqueous pesticide composition; and    (3) an apparatus for removing soft-bodied animals from potted plants, comprising an acidic pesticide recapture tank (120), a filter, an acid transfer pump, a transfer line, a sprayer line, a sprayer head, and a monitoring and pH control meter, where the acidic pesticide recapture tank is capable of holding the potted plant, and is separated by a filter, typical fluid recycle lines are interconnected among the various components of the system with e.g. the inlet side of the outlet transfer line (140) connected to the outlet of the transfer or recycle pump (130), as the pesticide is pumped through the sprayer line (150) into the sprayer head (160), the pesticide is transitioned into droplets that shower the plants of interest, which are sitting on acidic pesticide recapture tank, and power or air pressure lines supplying power to spray the pesticide onto the plants of interest is present as a part of the pesticide recycling system.    DESCRIPTION OF DRAWING(S) - The figure shows an apparatus and method for killing frogs and frog eggs on plants.    Acidic pesticide recapture tank (120)    Transfer or recycle pump (130)    Transfer line (140)    Sprayer line (150)    Sprayer head (160)
