and how does one go about euthanizing tree frogs?

I only euthanize the invasive Cuban tree frogs. It's is so bad that it's actually against the law to release a Cuban tree frog back into nature, and as any biologist will tell you, euthanasia is the best thing to do as Cuban tree frogs go, since this is not even their natural habitat and they are causing such major damage to native wildlife It's easy to identify them if you know how.

Once I have caught one and identified it, I put on latex gloves (when they get to a certain size, they secrete a mucous that's not harmful to us, really, but it does sting). After that, I hold the frog in my hand while I apply a generous dab of 20% benzocaine to his back and belly. Benzocaine is something that you can find in pain relief cremes, itch cremes, OraJel, and so on.

Benzocaine knocks the frog unconsciousness in about three minutes. When the frog is out, I put him in a plastic bag and lay it in the freezer. I leave the frog in there for two days minimum to assure that he is dead.

Biologists who have studied these amphibians agree that it's the most humane method. I felt bad when I first started to euthanize them, even though I knew what damage they cause to this ecosystem. But after I saw a Cuban tree frog eat a live, croaking native frog, my sympathy for them went away.

If you want to read more about Cuban tree frogs and their invasive nature in the United Stated, you can go to this link: http://ufwildlife.ifas.ufl.edu/cuba.....rog_inFL.shtml - it's a university site, and the professor who runs it has studied amphibians and especially Cuban tree frogs for quite a while.

kind of like cane toads in their popularity, eh?

.... hmmm... they would be fun to practice taxidermy on rather than waste their little lives

i got a good LOL off of this though

HAHA I know, I saw that picture too. They're total gobblers, they eat like crazy, but I guess some of them aren't bright enough to pay attention to what they eat, lawd.
