How do you capture a tree frog other than the hand?

A net would work perfectly. Or a cup if your fast enough. catch it like you'd catch a spider or something slam the cup hard around him and drag it until you remove the cup from the tree. Fun fact, if you put frogs in cold water and slowly raise the temperature they will sit there until they die from the boiling water. It's not nice but it could be good if you don't like hand killing animals and you were in a survival situation.
