The Australian green tree frog is one of the most common frog species in their homeland. For humans, they make great pets and can be an ideal form of pest control if they live near your home. But while they might look harmless, that changes if you’re…say, an innocent snake or giant spider just trying to get on with your life.

Then, these frogs turn into deadly, effective predators…

Green tree frogs are most easily identified by their bright green coloring. For anyone who’s familiar with the frog in their native Australia, they’re equal parts pest and pest controller.

They can be found in urban areas, forests and woodlands, and wetlands. Out in the suburbs, they have a nasty habit of making a home for themselves near shower blocks and water tanks.

For example, Redditor ElfBingley had a problem flushing their toilet about a year ago. When they went to check the tank, they found these buggers inside. Talk about an infestation.

Still though, just because they’re frogs doesn’t mean they don’t occasionally put on a display of unusual badassery. Take this tree frog…he’s going toe to toe with a rather large snake.

Not only do tree frogs hunt snakes, they’ve also been known to occasionally take up residence outside of caves and catch bats to eat. Yikes!

Aside from snakes and bats, tree frog diets also include mice and giant spiders.

When it all comes down to it, personally, I’d much rather have a frog infestation than a snake problem on my property.
