We recommend you use Talstar P. Talstar P should be applied every 30 days at the 1fl oz per gallon of water usage rate from August through to the first frost. If you need to spray high areas you may need to use something like the Chapin Slide Pump Sprayer 6002. This sprayer is much different than most sprayers but there is a video located on the page we have linked for you that will show you how to use the sprayer.
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).
