Yes, Talstar P will kill ticks. We also recommend mixing in an IGR to help break down the reporductive cycle. You can use something like Nyguard IGR. You would mix 1 oz Talstar with 3-8 ml Nyguard IGR into one gallon water.
We apologize that there appears to be fungus like substance in your bottle of Talstar P. There was an issue with one Lot of 3/4 gallon Talstar from FMC last year. We would be more than happy to ship you a new bottle or refund you for this bottle from the defective Lot. You can call us at 866-581-7378 to follow up of this matter up.
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).
