Martin's Permethrin 13.3% and Talstar P should not be mixed together. Making a pesticide too strong can actually backfire. Areas that are treated with overly concentrated spray will be repellent and insects will simply avoid the treated areas, prolonging the infestation. If you would like to give us more information on what type of pest(s) you need to treat, we can recommend which product would be best for your needs.
