I like the treat the outside of my home every three months with Termidor for ant prevention. Recently, we have been inundated with stink bugs and I would like to treat the outside of the home with Talstar Pro (because of the good reviews it has with stinkbug control). Since it is recommended that Talstar be used monthly for stink bugs, there would be months where I am using both the Talstar and the Termidor. Is this ok---do they affect each other's ability to kill bugs?
Termidor SC is a non-repellent insecticide. This means that ants and other 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 the ants 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. Ants may avoid the areas treated with Talstar and those ants 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 the Talstar P higher up around window frames, window sills, door frames, any cracks and crevices around foundation or where caulking around windows and doors has opened up, around vents leading inside, and around lights (these bugs are attracted to the light from windows, doors, etc).
