Tiny insect, cottony maple scale, causing big annoyance in Douglas CountyWhen looking into your trees, does it appear that someone has glued popcorn to the branches? Worse yet, when you park your car in the shade, do you come back to find sticky sap covers it? Do you find that same sticky substance all over your lawn, windows and patio furniture? The cause of this annoyance is a tiny insect known as cottony maple scale.
