Talstar will not harm chameleons or lizards, but it will kill the insects in the area they feed on so you may notice a decline in the number you see around as their food sources will be more scarce. Butterflies and bees are insects and will be affected by an insecticide like Talstar and any other product the same way the target pests like ants and spiders would be. The best way to reduce the chance of the Talstar affecting the bees, butterflies and beneficial insects is to spray later in the day when they are not active and are back in their homes/nests, and try to avoid blooms of flowers and plants they would be using for pollenation. Most structural insects you would be targeting are not going to be landing in the same places they would be so it helps keep you from doing as much damage.
According to the Talstar P (Talstar One) product label: Chinch Bugs infest the base of grass plants and are often found in the thatch layer. Irrigation of the grass area before treatment will optimize the penetration of the insecticide to the area where the chinch bugs are located. Use higher volume applications if the thatch layer is excessive or if a relatively long mowing height is being maintained. Chinch Bugs can be one of the most difficult pests to control in grasses and the higher application rates (Up to 1 fluid oz. per 1000 square feet) may be required to control populations that contain both nymphs and adults during the middle of the summer.
Talstar is our most popular selling product for mosquito control. It is a liquid concentrate that you mix with water and apply using any hand pump sprayer or backpack sprayer. The key is to apply it to all shrubs, trees, and other foliage around the house or patio you are trying to provide relief at. 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. It should be applied every 30 days for optimum control. Best of all it will not harm any birds in the area.
