Why is My Street/Sidewalk/Car So Sticky?
As summer approaches so do the Wooly Aphid problems on the Chinese Hackberry trees.
This aphid infests hackberry, especially Chinese hackberry (Celtis sinensis), throughout the state. This aphid was accidentally introduced into the United States in the late 1990s and also occurs from Florida to Texas and northward to at least Tennessee. Its copious honeydew excretions create a sticky mess and promote the growth of blackish sooty mold on leaves and surfaces beneath infested trees.
