You cannot mix Termidor SC with Demon WP nor would you want to. Termidor SC is a non-repellent product that works with a delayed reaction time and a transfer effect. Termidor SC also has a very limited label that only allows you to use it on or immediately adjacent to a structure. Demon WP on the other hand is a broadly labeled synthetic pyrethroid that will kill the insects that walk over treated surfaces. If you mix the two together you will be losing the non-repellent factor and transfer effect of the Termidor SC and you will be severely limiting the places you can spray the Demon WP. Termidor SC is not labeled to be tank mixed with other products.
