Can these two types of products be mixed together in a sprayer and sprayed at the same time?
These products should not be mixed together. There is no valid reason to mix Demon WP/Cyper WP and Talstar P/Bifen IT together. Talstar P/Bifen IT is a synthetic pyrethroid and Demom WP/Cyper 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.
