Talstar P Professional Insecticide would not be recommended for use if you need to treat wood directly. It only sits on the surface of wood and would not penetrate. It used to be used as a perimeter treatment to the soil in a trench around the home until non repellent products like Termidor SC were developed. For treating wood directly, a better option would be Bora-Care, either sprayed or painted onto the rafters. We have great guides for treating both subterranean and drywood termites that would be helpful to review as well.
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.
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.
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.
