Fungus gnats. Root weevils. Thrips pupae. Grubs. If it lives underground and damages your plants, this mix is built to end it.

Triple Blend Beneficial Nematodes

Three Species. One Goal: Wipe Out Soil Pests.

This blend combines three of the most effective species of entomopathogenic nematodes:

• Steinernema feltiae – Stays near the surface to target fungus gnat larvae, shore flies, and thrips pupae

• Heterorhabditis bacteriophora – Dives deeper to hit grubs, root weevils, and other root-feeding pests

• Steinernema carpocapsae – Attacks in the top layer of soil; great for cutworms, armyworms, and borers

Together, they deliver fast-acting, full-depth protection across a wide range of soil-dwelling pests.

Why Use the Triple Blend?

Whether you're running a greenhouse, grow tent, garden bed, or orchard, this blend works across crops and pest types—without needing a degree in entomology to deploy it.

Where It Works Best

• Soil temperatures: 53°F and up

• Environments: Greenhouses, indoor grows, raised beds, garden plots, field crops

• Humidity: Maintain even, damp moisture for 7–14 days post-application

• Light exposure: Apply early morning, evening, or on cloudy days (UV-sensitive)

How Much to Use

Use higher rates or reapply more often in hot spots, propagation areas, or known problem zones.

How to Apply

1. Pre-water soil before applying

2. Mix nematode powder with 1–5 gallons of non-chlorinated water (59–69°F)

3. Apply using a watering can, pump sprayer, or through irrigation

4. Lightly water again afterward to move nematodes deeper into the soil

5. Maintain even moisture for two weeks—don’t let it dry out
