NEMAforce™ SF

Beneficial Steinernema Feltiae Nematodes for Biological Pest Control

NEMAforce™ SF contains live Steinernema feltiae beneficial nematodes — a highly effective biological control for fungus gnats, thrips, shore flies, and other soil-dwelling pests commonly found in greenhouses, indoor grows, nurseries, gardens, and field production.

These entomopathogenic nematodes actively seek out insect larvae and pupae below the media surface, releasing a naturally occurring symbiotic bacteria (Xenorhabdus spp.) that kills host insects within 24–48 hours.

Why Growers Use NEMAforce™ SF

Targets fungus gnat larvae, thrips, shore flies, and mushroom flies
Excellent for greenhouse, indoor, and nursery pest management
Works below the soil surface where sprays often miss
Suitable for ornamentals, vegetables, hemp/cannabis, mushrooms, soft fruits, and tree nurseries
Compatible with standard sprayers and irrigation systems
Ideal for integrated pest management (IPM) programs

How It Works

Steinernema feltiae are intermediate foragers that live primarily within the top 1–2 inches of growing media. Once they locate a host insect, they enter through natural openings and release symbiotic bacteria that quickly kill the pest. The nematodes then reproduce and continue searching for additional hosts.

Application Guidelines

Optimal soil temperature: 50–78°F
Apply with standard spray equipment or irrigation injection systems
Keep media moist before and after application
Maintain constant agitation during mixing and spraying
Remove filters finer than 50 mesh from equipment
