I'm considering bifenthrin granules to complement spraying, which has had poor residual performance so far. The granules would be spread widely and hard to water-in. Watering appears to (1) help activate the chemical and (2) drive it into the soil. I don't need the latter, and if my concern is residual performance, might it not be better to let the stuff sit and gradually activate from ambient moisture? If they will... the label says water-in for most bugs, but oddly not for scorpions.
Yes regardless of what insect you're treating for, Talstar PL needs to be watered-in in order to activate the active ingredient. Granules can typically last 2-3 months whereas liquids like Talstar P? will last about 30 days maybe more on outside surfaces. For scorpions specifically you would want to go with the Cy-Kick CS? that will sit on top of the surface better than granules and being microencapsulated will last on outside surfaces closer to 60 days. The Talstar PL granules would be great to use for the insects the scorpions feed on though.
