Will this product help control tent caterpillars in my large American Elm trees?
Criterion 75 WSP is great for preventing tent caterpillars in the spring when they are not as active. You should use Criterion as a soil drench around the root system of the tree. For issues you have right now, you should use Talstar from a powered sprayer directed at the tree limbs and the webbing from the tent caterpillars.
