White Scale On Crepe Myrtle Bark Scale Treatment
Creepy looking white scales are not uncommon on crepe myrtle trees. They look like little white spiders or worms crawling around inside the tree’s leaves. If you have ever seen these things, then you might already be familiar with them.
These little critters can cause problems if they become infected and start growing into other parts of your house.
The most common way to get rid of crepe myrtle scale is to prune it off. You can either use a sharp knife or simply cut out the affected area. However, some people prefer to try something else first.
There are several ways you could go about treating crepe myrtle scale:
You could spray bleach on the affected areas and wait until it dries before applying any kind of fungicide or insecticidal soap.
You could soak the affected areas in vinegar and let it sit overnight. This will kill all the bugs living there.
You could apply a natural product such as lemon juice or tea tree oil to kill any remaining insects or mites. You can also use a mixture of natural oils.
You can apply any kind of dormant oil at the beginning of winter to make sure that none of the insects are going to hatch in spring. You could also use a horticultural oil, which will smother the insects and kill them slowly over time.
There are several other ways you could go about treating crepe myrtle scale, but these are the most common ones. You will have to keep track of which one works best for you.
How To Get Rid of Crepe Myrtle Scale Insects:
What are Crepe Myrtles?
Crepe myrtle (Lagerstroemia) is a species of flowering plant in the family Lythraceae, native to eastern Asia (Japan, China, Korea). There are also a few species native to southeastern United states. They were given this common name due to their thin and wrinkled woody fruit.
Crepe myrtles are deciduous trees that are either grown as specimen trees or in groups, where they thrive. They can grow from 4 to 40 feet tall, depending on the species or cultivar. Their flowers bloom from spring all the way through fall.
They prefer full sun to partial shade and can grow in nearly any soil type, except for extremely wet or dry areas. Crepe myrtles are hardy and can grow in nearly all zones of the US, except for the colder areas of zone 3 and higher.
What is Crepe Myrtle Scale?
Scale insects feed on sap, which is usually found in evergreen trees and shrubs. There are many types of scale insects, but the most common are soft scales and armored scales. Soft scales have a white, mealy appearance, while armored scales are hard to the touch.
