With quick knockdown and long-lasting control, Prescription Treatment brand Alpine Flea Insecticide with Insect Growth Regulator (IGR) provides reliable flea control, according to the manufacturer. Multiple active ingredients allow the product to kill adult fleas for up to 30 days, and hatching eggs for up to seven months. The pressurized formulation doesn’t soak carpets; homeowners can re-enter sooner than with competitive products. In addition, Alpine WSG Water Soluble Granule Insecticide is a new, non-repellent product that controls several common pests, including fleas and ticks. It’s easy to use, has a broad label, and mixes into a clear, odorless solution that doesn’t stain and can be used both indoors and out.
