I want to mix Suspend Polyzone with Demon WP for outdoor insect control. Can I mix these two insecticides?
You cannot mix Demon WP with Suspend Polyzone. Both of these products are 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.
