Beneficial Nematodes Hb + Sf + Sc | Triple Blend Mix

$14.99

This is safe, effective biological control for indoor and outdoor use. People, pet, and planet-safe, and trusted by professionals. Application is simple: mix the easy-release powder with water and apply like you're watering your plants, no special equipment required.

Broad-Spectrum Soil Pest Control

Different pests hide at different depths and behave in different ways — some sit at the soil surface, some burrow deep, some are only vulnerable during a narrow window of activity. Rather than choosing one nematode species and hoping it matches your pest, Triple Blend combines HB, Sf, and Sc into a single release, covering the ambush, intermediate, and cruiser foraging strategies at once.

It's the broadest-coverage option in the nematode lineup, well suited to gardens and growing areas dealing with more than one type of soil pest at a time.

What Are Beneficial Nematodes?

Each species in the blend brings a different strength: Hb actively cruises the soil to reach deep, sedentary pests; Sc waits near the surface to ambush mobile pests like fleas and caterpillars; Sf works the upper soil layer with an intermediate strategy well-suited to fungus gnats and thrips pupae. Together, they give a single application meaningfully wider reach than any one species alone.

What do Sc Nematodes Target?

Since it contains all three species, Triple Blend's target list is the full pest matrix: armyworms, caterpillars, cutworms, webworms, codling moth, and other moth larvae; white grubs, Japanese beetles, and other beetle larvae; billbugs, weevils, and other grub-stage pests; borers across multiple crops; fungus gnats, shore flies, crane flies, and other fly larvae/maggots; and ants, fleas, termites, thrips pupae, and ticks.

Beneficial Nematode Pest Chart

How It Works

The life cycle follows the same pattern as other beneficial nematodes: eggs hatch into non-feeding juveniles, which molt into infective juveniles that search for hosts, infect them with bacteria, and feed on the cadaver before repeating the cycle. What makes Triple Blend nematodes unique is its blend of species to cover all soil pest levels.

When to Use Sc Nematodes?

Optimal application when soil temperature is between 60°F - 83°F

  • Early Spring (Mar-Apr): Target overwintering pests once soil temperatures reach 42°F+
  • Late Spring/Early Summer (May-Jun): Interrupt first-generation pests to prevent summer pest outbreaks
  • Mid-Summer (Jul-Aug): Maintain control during peak pest activity
  • Fall (Sept-Oct): Reduce next year's pest problems by applying nematodes before pests go into dormancy for winter

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.

Application Rate
Preventative/Light Infestation 5 million nematodes per 1,250 sq. ft.
Moderate/Heavy Infestation 5 million nematodes per 250 sq. ft.

 

Soil Temperature & Moisture

  • Optimal Soil temperature: 60°F-83°F (General soil temperature 42°F-95°F)
  • Sc needs consistently moist soil. Avoid drying out
  • Keep soil moist for two weeks following application; avoid runoff

Application

Nematodes aren't a chemical, so effectiveness isn't reduced by the water volume used. Adjust concentration based on infestation severity and area size. Introduce indoors at any time, or outdoors in the morning, evening, or on a cloudy day; nematodes are sensitive to UV light, so direct sunlight should be avoided.

Application Instructions

  1. Prepare Soil — ensure soil is moist before application; dry soil prevents nematode movement.
  2. Activate/Mix Solution — mix nematodes with 59–69°F water; water volume depends on infestation level and treatment area size.
  3. Apply Evenly — distribute using a sprayer, watering can, or irrigation system.
  4. Keep Moist — water immediately after application and maintain soil moisture for 2 weeks; avoid runoff or waterlogging.

Watering Can or Pump Sprayer:

  1. Moisten the soil beforehand to improve habitat; avoid runoff.
  2. Mix nematodes with 1–5 gallons of water (59–69°F) to cover the desired area, diluting as needed for coverage.
  3. Apply the solution to the desired area — full, even coverage isn't necessary, since nematodes will move through the soil on their own. Use within 6 hours of activation.
  4. Water the treated area immediately after application, and keep soil moist for two weeks.

Hose-End Sprayer:

Use room-temperature water and let the nematode powder sit for 15 minutes to fully dissolve before spraying. Remove any screen filter first.

 5 million Add all nematodes to the reservoir, fill to the 5 gallon mark. Spray until empty.
10 million Add all nematodes to the reservoir, fill to the 10 gallon mark. Spray until empty.
25 million Divide in half. Fill reservoir to the 15-gallon mark, mix in one half, spray until empty. Repeat twice.
50 million Divide into thirds. Fill reservoir to the 15-gallon mark, mix in one third, spray until empty. Repeat three times.


Other Hose-End Sprayers (dial-style):

Use room-temperature water and let the nematode powder sit for 15 minutes to fully dissolve before spraying. Remove any screen filter first.

 Package Size Preventative/Light Moderate/Heavy
5 million 4 oz 8oz
10 million 4 oz 8 oz
25 million 1.5 oz 8 oz
50 million 4 tsp 5 oz


Pairing for Full-Spectrum Soil-Pest Control

Sf nematodes work well alongside Hypoaspis miles for layered soil coverage. Nematodes work deeper in the soil profile targeting grubs and beetle larvae, while Hypoaspis miles patrol the surface layer for fungus gnats and thrips pupae. For broader soil-pest coverage in a single treatment, HB is also available blended with SF and SC nematode species.

Safe, Sustainable Pest Management

  • 100% natural — no chemical residue
  • Safe around people and pets
  • Safe for use on edible crops
  • Fits seamlessly into existing IPM programs
  • Requires no protective equipment

Storage

Your nematodes arrive in a bubble mailer with an ice pack — the ice pack will likely be melted and the package may feel warm on arrival. This is normal; the product remains safe to use. Refrigerate the unopened package until ready to apply. If storage is necessary, store at 36–45°F for no more than 30 days, in a dark place. Do not freeze.
