Those yellow and brown patches of grass are sod webworms taking over the yards of some unfortunate homeowners. The larvae of sod webworms feed on the sod and can devastate a lawn in short order.
Summit Biological Caterpillar & Webworm Control contains BTK (Bacillus thuringiensis kurstaki) which successfully kills webworms and caterpillars without impacting other species or the environment.
Summit® Biological Caterpillar & Webworm Control is Mother Nature’s way of controlling sod webworms and other caterpillars. It is available in a one-pint concentrate bottle, a one-quart concentrate bottle and a ready-to-spray one-quart hose-end bottle. Summit® Biological Caterpillar & Webworm Control is available at garden centers, hardware stores and here on this website.
