My book called The Organic Gardners Handbook of Natural Insect and Disease
Control edited by Barbara W. Ellis and Fern Marshall Bradley says
Steinernema carpocapsae lives closest to rhe soil surface and successfully
controls carpenterworms, currant borers, earwigs, navel orangeworms, onion
maggots, pillbugs, seedcorn maggots, sod webworms, sowbugs and strawberry
Heterohabditis heliothidis ranges deeper in soil. effectively controlling
billbugs, blackvine weevils, corn rootworm larvae, Japanese beetle grubs,
masked chaferrs, mole crickets, and wireworms.
Both types show promise against armyworms, cabbage root maggots,codling moth
larvae, Colorado potatobeetle larvae, cutworms and rose chafers.
It says that as temperatures drop the nematodes burrow deeper into the soil
and rise as the temperatures do but their return lags behind the arrival of
early spring pests so reintroduction each year is necessary.
mix with water and apply with watering can or sprayer apply 100,00 to 500,000
per square yard and soak with 1/2 to 1 inch water after application to carry
them into the soil.
well guess i will be using these next spring.
