Pest Alert: Crape Myrtle Bark Scale

Signs of Infestation

One noticeable sign of a CMBS infestation is a black, sooty mold on the bark and leaves. This mold grows on the honeydew secreted by the insects as they feed on the sap. While the sooty mold doesn’t cause harm directly, it can reduce photosynthesis by covering the leaves and limiting sunlight exposure. In addition, CMBS causes slow growth, wilting, reduced flowering, and ultimately tree removal. Arborists also check for clusters of white or gray scales along the bark, which is a primary sign of infestation.

Lifecycle and Spread of Crape Myrtle Bark Scale

The crape myrtle bark scale reproduces quickly and can spread easily from tree to tree. This pest has several life stages, from eggs to crawlers to adults. Crawlers are mobile young scales that move around and attach to new areas of the tree, spreading to neighboring plants. These pests spread through direct contact or contaminated tools and equipment. Also, wind, animals, and human activity can spread these critters to healthy trees. Regular inspections and maintenance by a qualified tree service provider ensures early detection and intervention before things worsen.

Managing Crape Myrtle Bark Scale

Managing CMBS infestations requires a physical and chemical control methods, hence the need to work with a trustworthy tree care company. DIYers often prune heavily infested branches to limit the scale population. In addition, professionals can recommend horticultural oils and systemic insecticides during the crawler stage. If you are considering a DIY approach, apply chemical treatments carefully with the help of a professional tree service provider.

Preventing Future Infestations

Preventing infestations is essential for maintaining healthy crape myrtle trees. Regular monitoring is one of the best strategies, as it enables early detection and quick action if any signs of CMBS appear. You should also avoid over-fertilizing crape myrtles, as lush, excessive growth can attract pests. Maintaining proper pruning practices and sanitizing gardening tools between uses can further reduce the chances of spreading CMBS. If CMBS is common in your area, choose pest-resistant varieties of crape myrtle to reduce the risk of infestation.
