Q.Crepe Myrtle tree
I have had my tree for about 10 years and this year is the first year some insect has been chewing on the leaves. Have not seen any insects on the tree. Have no Japenese beetles in this part of the country. Please help.
Though there are several pests that it could be, such as aphids, scale or mealybugs, they are all treated the same way - with a general insecticide. I personally like neem oil as it is organic and safe to use. Here is more info: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
