Steinernema carpocapsae (Sc) is the "Ambush Predator" of the nematode family. Unlike the deep-diving Hb or the cruising Sf, Sc nematodes have a unique behavior called "nictation." They stand on their tails near the soil surface and wave back and forth, waiting for a pest to brush past them. When a mobile insect touches them, they latch on and attack instantly. This makes them the absolute best choice for highly mobile pests that travel across the soil or live in the grassy thatch layer, such as fleas, caterpillars, and sod webworms.

• Scientific Name: Steinernema carpocapsae

• Best For: Fleas, Caterpillars (Cutworms, Armyworms, Sod Webworms), and Crane Fly Larvae.

• Key Feature: The "Stand and Wait" Ambush—they latch onto pests moving across the surface.
