Hello,
      The recent messages re geckos requiring euthanasia and this being problematic on Hawaiian islands, stimulate 3 comments.
      1, A gecko that drops off the ceiling and/or lands other than on its four feet is probably sick to begin with. 
      2, Even geckos don't live forever. What does everybody do with the dead pets? They should be donated (with maximum info on their origin, age etc.) to some public museum collection.
      3, To my understanding, on Hawaii, the colonizing day geckos are semi-banned not for their endangering the local insects (this is already done by the local geckos) but because they displace the local geckos. This of course means that they displace Hemidactylus frenatus, who since arrival in the 1940s has been displacing Hemidactylus garnotii, who arrived much earlier. The moral difference between the waves of invasion is that the early invasions were unintentional (which is natural for commensal geckos), whereas the latest is supected of having been intentional (artificial).
      Hoping to have served, Yehudah
