After doing my senior neighbor's leaves who has a lawn with no visible signs of poison ivy, how did I break out like never before? They get lawn maintenance all year long but at the end of the year had to do their own for some reason. This is why I helped because I sensed a potential danger. My wife accidentally blew a small amount of leaves with the blower which I thought wasn't a big deal at the time.
So no signs of poison ivy plants yet poison ivy? Now I was sure they were spraying it.
