Chuck from Billings Mo writes,

Can I mix/spray Termidor SC in the same equipment that I use for Talstar P?


If the equipment has been tripled rinsed and the nozzle and wand have been rinsed out, you can use them in the same sprayer just not at the same time. Termidor SC is a non-repellent insecticide. This means the insects cannot tell that it is there and they will readily walk over treated areas. Termidor SC also has a delayed reaction time and a transfer effect which allows them time to get back to the colony and spread it around before they succumb to the effects of the product. Talstar P on the other hand is synthetic pyrethroid which many sensitive insects such as ants can detect. Insects may avoid the areas treated with Talstar and those that do cross over treated areas are the only ones that will be killed by the product. Talstar P does not have a transfer effect so it will not be transferred back to the colony. While the Termidor SC will not actually be deactivated by Talstar P, it will be much less effective if it is over-sprayed with Talstar P. You can spray Talstar P on your trees, bushes and lawn for mosquito control as long as you are not actually overlapping the areas where Termidor SC was applied.
