Testing a Euthanasia Spray for Control of Invasive Frogs

Dr. Johnson and Monica McGarrity are collaborating 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 Cane Toads and Cuban Treefrogs. Since frogs have thin, absorbent skin, the spray quickly soaks in, anesthetizes, and then euthanizes the frog -- the frogs are comatose within seconds. This product is being prepared for the market in Australia, and will hopefully be coming to a hardware store near you in the near future.
