Sc Nematodes

Sc nematodes are specialized for pests that move quickly or live in the upper thatch layer of lawns.

• Primary Targets: Flea larvae and pupae (in soil/yards), Cutworms, Sod Webworms, and Armyworms.
• Secondary Targets: Crane Fly Larvae (Leatherjackets), Peach Tree Borers, and some Weevils.
• Wood Borers: Uniquely, Sc is often used to treat wood-boring insects by injecting the nematode solution directly into the borer holes.
• Mechanism: They do not chase prey deep underground; they wait in the topsoil/thatch for the pest to come to them.

Because they hunt near the surface, Sc nematodes are hardy but require moisture to facilitate their "ambush" posture.

• Temperature: They are versatile, active between 50°F - 86°F (10°C - 30°C).
• Moisture: Essential. They need a moist thatch layer to "stand up" without drying out. If the lawn is bone dry, they cannot hunt.
• Location: They stay in the top 1–2 inches of soil or turf thatch.

Trying to decide between Sc and the other species? Here is the breakdown.

• Choose Sc (The Ambusher): If your problem is Fleas or Caterpillars (Webworms/Cutworms). These pests move across the surface, making them perfect targets for Sc.
• Choose Hb (The Hunter): If your problem is Grubs (Japanese Beetles). Grubs are deep underground and don't move much, so the surface-dwelling Sc won't find them effectively.
• Choose Sf (The Patroller): If your problem is Fungus Gnats. While Sc can kill gnats, Sf is generally more aggressive against the specific larvae found in potting soil.
• The "Flea & Tick" Strategy: For total yard protection, use a mix of Sc (for Fleas) and Hb (for Ticks/Grubs), or simply use our Triple Blend.

Application is similar to other nematodes, but focus on the areas where pests travel.

• Preventative Rate: Apply 1 package (e.g., 5 Million) per 250 sq. ft. every 4–6 weeks during flea/caterpillar season.
• Curative Rate: For active flea infestations or lawn damage, double the density (e.g., 5 Million per 125 sq. ft.) and apply every 7–10 days for 3 rounds.
• Prep: Mow the lawn to expose the thatch layer. Water lightly before application.
• Mix: Dissolve the carrier into water and stir vigorously.
• Apply: Use a hose-end sprayer (filter removed) or watering can. Focus on shaded areas, under porches, and dog runs where fleas congregate.
• Post-Care: Water immediately after to wash them off the grass blades and into the thatch. Keep moist for at least 3 days.

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

Viability: They look like a dusty paste or powder. They wake up when mixed with water.

Storage: Refrigerate immediately. Store at 38-42°F for up to 4 weeks. Do not freeze.

No. Nematodes live in the soil, not on your pet. They kill the flea larvae and pupae in the ground, stopping the next generation from jumping onto your dog. You still need to treat the dog for adults, but the nematodes break the life cycle in the yard.

We generally advise against it. While they can kill fleas in carpet, you must keep the carpet damp for 3+ days for them to work, which creates a high risk of mold and mildew. We recommend using nematodes outdoors to stop fleas from entering, and using dry methods (vacuuming/steaming) indoors.

When a cutworm or armyworm crawls over the soil surface at night, the Sc nematodes latch onto its belly, enter the body, and release bacteria that kills the caterpillar within 48 hours.

Yes! For borers (like Iris Borers or Peach Tree Borers), you can use a syringe to squirt a concentrated nematode solution directly into the borer holes. Plug the hole with clay or wax afterwards to keep moisture in.

Yes, immediately. Sc nematodes are completely harmless to mammals. Your pets can play in the yard right after you water them in.

Sc has some effect on ticks, but Steinernema feltiae (Sf) or a Triple Blend is generally considered slightly better for tick control. However, Sc is the undisputed king of Flea control.
