I live fairly close to Las Vegas, Nevada. Lots and lots of sunshine. I'm looking for a product that will provide the longest residual killing power considering the high UV here in the desert. Target pests are cockroaches, spiders, scorpions, and ants. I have ordered Talstar P for inside use, and Demon WP for outside, in the hopes that the Demon WP will have greater UV resistance and provide longer residual action.
You picked the exact products we would have recommended for your use. Demon WP will hold up very well outdoors as wettable powders are considered very stable formulations. Of course the only downside to wettable powders is that they can leave a white powdery residue behind so we usually will recommend using a product such as Talstar indoors if the powdery residue in a concern.
