"When multi-colored Asian lady beetles first invaded northern and western Wisconsin in the early 2000s, we had hundreds of potential customers calling with panic in their voices. We discovered Demand CS is, hands down, the best pesticide to deal with these pests. It provides fast enough knockdown to prevent them from entering the structure of houses, along with a long-lasting residual that will cover the rest of the pest season until the cold Wisconsin winter sets in. Demand CS also provides the added benefit of controlling spiders, wasps, yellow jackets, boxelder bugs, cluster flies and many other common fall invaders."
