Ernie from Olyphant Writes,
05/02/2013:

Can you spray trees in the early spring that have caterpillars in them?

Would you be able to make a dilution to be used in a pressure washer to reach high trees?

Answer:

You can start spraying when the caterpillars are young for best results. We recommend using the 1 fl oz of Talstar P per gallon of water ratio for the fastest knockdown and the longest lasting residual. As for using it in the pressure washer, we really cannot give any advice on that type of application as most insecticide (if not all) are not labeled for use in pressure washer.
