Demon WP and Suspend SC should NOT be mixed together. There is no valid reason to mix Demon WP and Suspend SC together. Suspend SC 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.
