Talstar P is known for being super gentle on plants and when it and Nyguard IGR are used as directed should not harm plants. Avoid spraying during the heat of the day to prevent burn.
Neither Talstar P Professional Insecticide or Hi-Yield 38 are systemic products. We are unaware of any systemic product that is labeled for use for spider-mite control as a soil drench. This pest is mainly treated with foliar sprays with something like Talstar P, Avid (which is a translaminar systemic – meaning absorbed through the leaves), or Hexygon DF.
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.
Talstar P is not labeled for use to control root aphids or for use in a vegetable garden. Pyganic Gardening or Azera Gardening can be used in and around vegetable gardens for aphids and a wide variety of other insects. Keep in mind that this is a persistant pest often brought into an area by infested plants or soils, so be sure that you are checking transpants and using clean soils in your garden.
