Hi, over the past month or so I've noticed this weird "stuff" around the side of my house amongst a whole bunch of deer tracks. It's white, and looks foamy, but it is definitely solid (I poked it with a stick). Unfortunately I have no idea what it is. At the very least I need to get the deer away from my yard.....but I just want to make sure it's from the deer as opposed to something else. Thanks!
