I walked around and checked out a small patch of maypop that I still have growing and didn't see any browsing activity on it. If they don't browse it around here then it's probably not something they'll mess with too much. I'm going to do some more spot spraying tomorrow to nuke that little patch.....it spreads like crazy if you let it. Unless you are in bad need of the biomass production then I'd probably start spot spraying it to get rid of it.
