You can apply Orthene 97 Spray Insecticide for scale in the crawler stage on trees such as crepe myrtle. Per the product label, you would apply 8 oz (1/2 lb) per 100 gallons to treat one acre. We recommending contacting a Master Gardener with your local Cooperative Extension office for assistance with the best time of year to treat this stage of scale insects.
