Can Demon WP be mixed with Suspend SC?
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.
