Hi-Yield 38 Plus is a concentrated permethrin insecticide for a wide range of crawling and flying pests, including ants, roaches, and spiders, around the home and yard. Permethrin is a synthetic version of the natural pyrethrins found in chrysanthemum flowers; it acts quickly and leaves a residual barrier that keeps working after it dries.

Mix and apply strictly according to the label, which lists the approved pests, sites, and rates. It can be used indoors and out. Wear appropriate protection while spraying, ventilate enclosed areas, and keep people and pets off treated surfaces until dry.
