There is no valid reason to mix Demon Max and Demon WP together. Demon Max is a synthetic pyrethroid and Demon WP 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.
