Easy release powder dissolves quickly and is trusted by professionals for its effectiveness. Nematodes work well in different temperatures and adapt to various weather conditions with ease.

Beneficial nematodes are microscopic worms found in soil that target young stages of pest insects, like larvae, grubs, nymphs, and pupae. These helpful creatures rely on moisture to move around and locate their prey. If it’s too dry, they can’t move well, and if it’s too wet, they might drown or get washed away.

Their life cycle starts when female nematodes lay eggs, which hatch into non-feeding juveniles. These juveniles molt several times until they become hungry infective juveniles. They actively search for hosts, enter them, and release bacteria that kill the pests. Within a few days, the infected insect dies, and the juveniles feed on it. This cycle repeats until conditions change.

When the food is gone, adult nematodes mate, and the females lay eggs, beginning the cycle again. This process repeats as long as the conditions remain suitable.

Pro Tips

• Release indoors at any time, or outdoors in the morning, evening, or on a cloudy day. Nematodes are vulnerable to UV light.
• Water the soil before application and keep the surface moist for two weeks after.
• Apply when soil is above 46°F; nematodes work best from about 55–86°F. If soil is warmer than 86°F, water with at least 0.1 inch before and after application.
• Use the mixed solution within 1–2 hours of activation.
• Identify the pest first; the Target Pests chart shows which species covers each one.
• Pesticides, wetting agents, and spreader-stickers can harm beneficial nematodes' survival. Broad-spectrum and systemic insecticides are toxic to them.

Chemical Compatibility

Some chemicals, including pesticides and fertilizers, can harm or even eliminate beneficial nematodes, reducing their effectiveness as natural pest controllers. To protect your nematodes, it's essential to check chemical compatibility before applying it to your soil.

To make it easier, we've created a detailed list of chemicals that work safely with beneficial nematodes, ensuring your garden stays healthy.

Introduction Sites

Beneficial nematodes can be used indoors, outdoors, or anywhere developing pests exist: gardens, greenhouses, indoor grows, houseplants, lawns, orchards, vineyards, and more.

Application Rates

These are general starting points. Actual application should be adjusted based on pest species, plant type, and infestation severity. Monitor pest and predator populations regularly to gauge how well the program is working.

Soil Temperature Range

Apply when soil is above 46°F. Nematodes slow down in cooler soil but aren't harmed, and work best from about 55–86°F.

Combined, the blend tolerates soil temperatures from roughly 46°F to 95°F (8°C–35°C), giving usable coverage across a wider seasonal range than a single species alone. All three species need consistently moist soil to move and hunt.
