These products should not be mixed together. There is no valid reason to mix Onslaught FastCap and Talstar P 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
