Talstar P is one of our most popular insecticide concentrates and should do a great job for you. Talstar is best applied with a sprayer. Mix 1/2 or 1 oz. of Talstar P in one gallon of water and apply to the outside foundation of the structure, approx. 3 feet up the side of the structure and 2 feet out from the structure. Also spray entry points into the structure such as around windows, pipes, doorways, etc. We sell several high quality sprayers which will last for years when maintained properly. Our most popular professional sprayer is the B&G 1 Gallon Sprayer + 18-inch wand - N124-S-18 and our most popular consumer sprayer is the Chapin Premier 1 Gallon 21220. We also have a great article called Apartment Pest Control for Building Owners that will explain step by step how you can keep pests out with a minimum of chemicals.
You can mix Talstar P with Precor IGR for flea control. According to the new Talstar P product label you can make applications as spot or crack and crevice treatments to areas frequented by pets, such as under bedding, rugs, next to furniture. Vacuum prior to treatment.
What this means is that you cannot broadcast spray your entire carpet with Talstar, you must limit the treatment to "spot" treatments (areas that 2ft x 2ft or less). If you only need to spot treat certain areas you can use Talstar for fleas. If you need to broadcast over entire carpeted rooms you should choose a product which is labeled for indoor broadcast sprays such as Onslaught or Permethrin SFR.
