Talstar P is only specifically labeled for clover mites and spider mites. It would be a good idea to get an identification of the mite species you are dealing with to be sure you choose the right product.
Per the Talstar P label, when applying mixed solution, the applicator needs to wear shirt, shoes, socks, pants and waterproof gloves. If applying in a non-ventilated area, applicator will need to wear a resperatory mask. You may want to look at our Basic Safety Kit for the necessary protective gear.
Most insecticides and herbicides are able to be tank mixed together, just make sure you follow each product label instructions for "tank mixing" instructions.
Talstar P (Talstar One) will kill Blind mosquitos, but since you listed that you live on a lake, EcoVia would be best. EcoVia EC can safely be applied in and around homes, businesses, near and over water such as boat docks and pool areas without harming aquatic life, as well as numerous other areas. EcoVia EC is safe to use around children and pets.
No, Talstar P cannot be applied to any edible vegetation.
Since aquatic life such as reptiles can be sensitive to insecticides, we do not recommend applying Talstar in any rooms while these animals are present, or in their habitats. It should be fine to use Talstar in other rooms where these animals are not kept.
The general rule of thumb for insecticide concentrates such as Talstar P is that they are good for about 3-5 years from the date of purchase as long as they have been stored at room temperature. If your Talstar is six years old, it certainly would not hurt anything if you wanted to try to use it, but if you find that it is not working as well as it used to, it may be time for some new product. You may also want to speak with the manufacturer directly to see what they would recommend. You can reach FMC at 800-321-1362.
Talstar works great for mosquito control and it can be used in your mister. The key is to apply it to all shrubs, trees, and other foliage around the house or where you are trying to provide relief. It should be directed not only on top of the leaves and plants, but on the underside of the leaves as well which is where the mosquitoes hang out during the heat of the day. Talstar should be applied every 30 days for optimum control.
