If they are treefrogs, don't feel sorry for them. THey have something in their blood that works much like antifreeze. They don't even burrow down to hibernate, they just get under the leaf litter so they are not visible. We have a ton of these red and black bugs all over our building, thousands of them probably looking for a place to hibernate themselves. The tree frogs I saw are too small to eat these bugs, but your might be bigger. WE had late hatches because of the drought so I think the ones no bigger than my pinkie fingernail ought to be much larger in size, tho they never get bigger than a quarter. My guess is somewhere under your house you might have had some water they hatched out of, and then they have finished up whatever food source was available and have struck out for new land. Putting them outside is the best thing for them, hopefully near some woods where they can do what they do best. I have a very soft spot in my heart for tree frogs. I think they are awesome.
