Can I mix this with CyperWP for outside use around the house
Will mixing bifenthrin with the cypermethrin degrade eithers efficiency or activity?
These products should not be mixed together. There is no valid reason to mix Cyper WP and Talstar P together. Talstar P is a synthetic pyrethroid and Cyper WP already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.
