You can prevent ants, flies and other insects from entering your home by applying a long lasting residual product such as Talstar. Talstar kills over 75 different insects and is safe to use indoors and outdoors, is gentle on plants, is odorless, dries clear, leaves no stains, is non-irritating to the skin, and won't break down easily with rainfall. We also suggest you use Integrated Pest Management or IPM. IPM is a step by step approach that helps you identify the pest and determine why that pest is there, and then determine how to exclude the pest in the future. Please read the IPM article to learn how to successfully stop pests before they become a problem.
Talstar P (Talstar One) is labeled to be applied to cracks and crevices indoors. Mopping should not be an issue, as Talstar is not labeled to be applied as a broadcast over the floor. If you were to mop along the edges of the wall where Talstar was applied, it would take it up.
We recommend you use Talstar P. Talstar P should be applied every 30 days at the 1fl oz per gallon of water usage rate from August through to the first frost. If you need to spray high areas you may need to use something like the Chapin Slide Pump Sprayer 6002. This sprayer is much different than most sprayers but there is a video located on the page we have linked for you that will show you how to use the sprayer.
