Mr. Weedy says: Be on the lookout for white aphids insect clustered at the tips of crape myrtle branches. Weed Pro lawn care’s tree and shrub program is proven effective in the prevention of these insects before they become a problem. If you decide to take on them yourself start off by washing them off with a water hose. Insecticides will be needed for control purposes. Crape Myrtle trees also attract Japanese beetles that eat the aphids. Please visit Weed Pro lawn care’s interactive website for free detailed information on these insects.
