Dr. Johnson and Monica McGarrity collaborated with Dr. David Dall and his Australian company, Pestat Pty. Ltd., to conduct field and laboratory trials of a new euthanasia spray for invasive frogs. This product, called HopStop®, contains only ingredients found in common household cleaning supplies but is highly effective for euthanizing frogs. Since frogs have thin, absorbent skin, the spray quickly soaks in, anesthetizes, and then euthanizes the frog -- the frogs are comatose within seconds.
HopStop® has recently been made available on the market in Australia, and may eventually be available in the U.S. for use managing our invasive amphibian pests, the Cane Toad (FL), Cuban Treefrog (FL), and the Coqui frog (HI).
