you capture a frog, please handle and dispense with it humanely:1)
if on the Big Island, take the frog to a local veterinarian
or wildlife shelter for euthanasia (have the frog properly
containerized to prevent spreading it into a non-infested
area en route), or 2) deeply anesthetize the frog
by applying a topical anesthetic (e.g. Orajel) and then dispatch
using a method that is accepted by the American
Veterinary Medical Association (see pp, 20-21, 28) including
deep freezing at 0 °C (-18 °F) only after the
frog has been rendered unconscious.
These methods have
been suggested by PeTA (January 2010).
