Talstar P Professional Insecticide is a water-based chemical and will not cause corrosion to stainless steel or galvanized metal. Keep in mind that you should not apply this product directly to food, feed, water, or sources for food or water. You also cannot apply this in a way that would contact the animals or their food or water. Keep in mind that a good fly control program includes the use of multiple control measures such as baits and traps, in addition to insecticides.
Talstar P cannot be used directly on vegetables or fruits that are going to be consumed. We do carry several products that can be used on cucumbers and other edible vegetation such as Sevin and Hi-Yield Indoor/Outdoor 10%. Always read the product label of the product you select to make sure it is labeled for the plant you want to spray and for the pest you are trying to eliminate. The product labels are available for each product on our site and you can see the links for them on each individual product page.
Talstar P is not labeled for general mites, though mange mites typically are on livestock or pets. For mange mites, we recommend Tengard SFR which could be used to treat the ground outside, as well as inside the home over a certain area. Tengard SFR can also be used on a dogs and other livestock (do not use on felines) to kill mites without harming the animal.
Talstar P CANNOT be applied to anything that you will come into prolonged skin contact with, so you cannot apply it to furniture. It should be applied to cracks and crevices and perimeter of the rooms only. For treating sensitive areas like your furniture, you should use Steri-Fab which is labeled for ticks and fleas as well as many other pests and can be applied to furniture, mattresses, pet beds, and all other sensitive areas. Below is a great article on treating indoors and the products that we would recommend for treatment inside the home for fleas and/or ticks.
