They got some BIIIIG spiders down there. I'd bet a dollar if that little girly fell asleep leaning against the tree she'd have a rude awakening.  My first thought seeing it was that a pressure hand can full of gas might have a hard time reaching the top of the tree, and it might be hard to spray all of the other buggers as they dropped out of the tree.  Soak it first and THEN light it from a distance. Or nuke from orbit, but I'm short on launch codes at the moment.
