Carl from Saint Charles, Il writes
These products should not be mixed together. There is no valid reason to mix PermaCap Cs and Talstar P together. Talstar P is a synthetic pyrethroid and PermaCap CS 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. If you want to make one of these products have a little extra oomph you can mix a natural pyrethrin with it such as Exciter. Exciter will give you a fast knockdown of pests that are present at the time of the application and the Talstar P or Permacap CS will give you a lasting residual.
