M. from Cincinnati, Oh writes,
Can Cyzmic be mixed with Onslaught in the same hand pump sprayer? Or should I use these separately?
These products should not be mixed together. There is no valid reason to mix Onslaught and Cyzmic together. They are both synthetic pyrethroids 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
