Triple Blend Nematodes for Broad-Spectrum Soil Pest Control

Because this contains three different hunters, it targets the widest range of pests.

• Surface Pests (Sf): Fungus Gnat larvae, Thrips pupae, and Fruit Fly larvae.
• Mobile/Surface Pests (Sc): Fleas, Caterpillars, Cutworms, Sod Webworms, and Crane Flies.
• Deep Soil Pests (Hb): Japanese Beetle Grubs, Chafer Grubs, Weevils, and other root-feeding larvae.
• How They Kill: Nematodes enter the pest through body openings and release symbiotic bacteria that kill the host within 24–48 hours.

Nematodes are microscopic aquatic worms that require specific conditions to survive and move.

• Moisture: They swim through the thin film of water coating soil particles. The soil must be kept moist (not soggy) for at least 2 weeks after application.
• UV Sensitivity: Direct sunlight kills them instantly. Always apply in the early morning, evening, or on a cloudy/rainy day.
• Temperature: The Triple Blend is formulated to work across a wide range of soil temperatures, generally between 45°F - 86°F (7°C - 30°C).

Not sure if you need the Triple Blend or a specific species? Here is how to choose.

• Choose Triple Blend (The Shotgun): If you have multiple pests (e.g., Gnats AND Grubs), or if you aren't sure exactly what bug is eating your roots. This is the best "general preventative" for lawns and gardens.
• Choose Single Species (The Sniper): If you have a specific, confirmed pest. For example, if you only have Fungus Gnats indoors, pure Steinernema feltiae (Sf) is often more cost-effective.
• Nematodes vs. Mites (Stratiolaelaps): Mites are a "Shield" (slow, long-term prevention). Nematodes are a "Bomb" (fast, immediate knockdown). Use Nematodes to wipe out an active infestation, then release Mites 2 weeks later to keep it from coming back.

Success depends on application density and timing.

• Preventative Rate: Use the standard package size (e.g., 5 Million for ~250 sq. ft.) every 4–6 weeks during the growing season.
• Curative Rate: For active infestations, double the density (e.g., 5 Million for ~125 sq. ft.). Apply every 2 weeks until pests disappear (usually 2–3 applications).
• Prep: Water your soil thoroughly before application. Nematodes cannot travel effectively in dry dirt.
• Mix: Dissolve the powder/gel into a bucket of water. Stir vigorously to break up clumps.
• Apply: Use a watering can, pump sprayer, or hose-end sprayer to drench the soil. Remove all fine filters or screens (50-mesh or finer) from sprayers, or the nematodes will get trapped.
• Agitate: Nematodes are heavy and sink quickly. Shake your sprayer or stir the bucket every few minutes to ensure an even spread.
• Post-Care: Water the area again immediately after application to wash the nematodes off the foliage and down into the soil. Keep soil moist for 2 weeks.

Packaging: Shipped in a dormant state in a carrier powder or gel.

Viability: They look like a dusty paste or powder to the naked eye. They become active only when mixed with water.

Storage: Refrigerate immediately upon arrival. Do not freeze. They will last 2–4 weeks in the fridge (38-42°F).

No. Beneficial nematodes are microscopic. You will not see them in the package or in the soil. The carrier material (powder/gel) is visible, but the worms are not.

Generally, no. In most climates, nematode populations will drop significantly over winter or during hot, dry summers. We recommend seasonal applications (Spring and Fall) for outdoor lawn protection.

Yes! This is the easiest way to treat lawns. Set the dial to a high ratio (like 1:15 or "free flow") and remove the internal filter screen. If you leave the screen in, you will filter out the nematodes and spray only water.

No. Beneficial nematodes are specific to insect pests. They generally ignore healthy earthworms, which are much larger and have different biology.

Yes, standard fertilizers are fine. However, avoid high-nitrogen chemical fertilizers or pesticides (fungicides/herbicides) within 3 days of application, as these can stress or kill the nematodes.

Nematodes are tougher than people think. They can survive short periods of heat during transit. If the ice pack is melted upon arrival, put them straight into the fridge. As long as they don't smell like rotting fish, they are likely still viable.
