It is. RoundUp or an equivalent works, from what I read. Gonna have to begin this Fall.
The woods are full of it, so it creeps out onto occupied properties.
OTOH, We wear high rubber boots in the woods and it will deter anyone using the cover to creepy-crawl homesteads, IMO.
I use a product called Compare-N-Save 41-percent Glyphosate Concentrate Grass and Weed Killer.
It works great, however, my neighbors do not take care of the back part of their property so I have to fight back with this spray once a month.
