How to Apply Triple Blend Mix

Apply indoors any time. Outdoors, stick to early morning, late evening, or a cloudy day; direct sunlight and UV rays kill nematodes. Wet the soil before and after application, and keep it damp for at least two weeks so all three species can move into position.

  1. Prepare the Soil: Water the treatment area first. Nematodes move through water, so dry soil stops all three species from reaching their targets, whether that's grubs feeding below the surface, fungus gnat larvae in the shallow zone, or fleas active right at it.
  2. Mix the Solution: Combine the blend with water between 59°F and 69°F. Water volume depends on treatment area size and infestation severity. Use the mixed solution within 1–2 hours; it stays viable up to 6 hours, but weakens the longer it sits.
  3. Apply to the Soil: Distribute the mixed solution evenly with a watering can, pump sprayer, hose-end sprayer, or irrigation system, whichever you already have on hand. Full, even coverage isn't necessary, since nematodes move through the soil on their own from there.
  4. Keep the Area Moist: Water lightly right after application, then maintain consistent soil moisture for two weeks. Avoid heavy watering that causes runoff, since that can wash nematodes out of the treatment zone before they reach any of the three soil layers.

Watering Can or Pump Sprayer

  • Moisten the soil beforehand to avoid runoff and improve habitat.
  • Mix 5 million nematodes with 1–5 gallons of water (59–69°F) to cover the desired area, diluting as needed for coverage.
  • 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. Keep pressure at or below 72 PSI and use a nozzle 0.8 mm or larger.

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.
