No, Bifen LP would not be effective for mosquito control. The adult mosquitoes actually hang out in trees and bushes and the larva develop in standing water. Bifen LP granules can only be used to treat lawns and soil for insect infestation. You can use Bifen IT which is the liquid formulation of Bifen to treat for adult mosquitoes. Mosquito larva can be eliminated with BTI Mosquito Dunks which can be placed directly into water sources such as ponds, unused pools and other areas of standing water.
Spring tails can be tough to eliminate because they reproduce very quickly. In almost every case where people have spring tails, they also have a moisture problem such as a leaking or sweating pipe, poor ventilation in their crawl space, lots of wet mulch right up next to their house, etc. You must locate and correct the moisture problem to get rid of the spring tails, insecticides alone will not do the job. We do carry Bifen L/P granules and Bifen IT liquid, both of which can help you to reduce the numbers of springtails.
We are not sure why this product does not have roaches on the label, but it is the same product as Talstar PL Granules, and roaches are listed on the Talstar granule product label.
