Broad-Spectrum Organic Control for Soil Pests
The 3-Way Blend combines three proven species of entomopathogenic nematodes — Steinernema carpocapsae, Steinernema feltiae, and Heterorhabditis bacteriophora — into one powerful, chemical-free soil drench. Together they cover a wider range of pests and soil conditions than any single-species product.
Target Pests
- Fungus gnats & shore flies
- Grubs, chafer beetles & weevils
- Cutworms & wireworms
- Fleas & cucumber beetles
Why the 3-Way Blend Works
-
Ambush + cruise strategy: S. carpocapsae waits near the soil surface for mobile pests; S. feltiae actively hunts through the substrate; H. bacteriophora pursues deep-dwelling grubs.
-
Wide temperature range: Effective from 50°F (S. feltiae) up to 82°F (S. carpocapsae), covering most greenhouse and garden conditions.
-
Fast-acting: Pests are killed within days as nematodes release a symbiotic bacterium toxic to the host.
-
Safe for plants, people & pets: 100% organic, OMRI-compatible, and earth-friendly.
-
Produced in vivo on sponge: Higher bacterial load than water-based formulations — a more potent product per million.
Application Rates
-
Coverage: 1 million per 1,000 sq. ft.
-
Depth:
Water plants to saturate the soil ½” deep for fungus gnats, 3-4” for grubs
-
Prevention: Apply seasonally. Active infestations: Weekly or monthly.
- Remove all filters/screens 50 mesh or finer from spray lines. Keep pressure below 300 psi.
- Use hose end sprayer with coarse spray and no filter
How to Apply
Mix sponge contents with water and apply via sprayer, injector (set to 1:100 dilution), hose-end sprayer, or watering can. Plug trays can be dipped directly in the nematode solution. Maintain adequate soil moisture before and after application to maximize mobility and effectiveness.
