Triple Blend Nematodes - FAQs
Why buy Triple Blend instead of a single species?
Because Sc, Sf, and Hb each work a different depth of the soil profile, and at different temperature ranges. Combining all three means one application covers surface-active pests, shallow-soil pests, and deep-feeding grubs at once.
Can all three species really be applied together without one interfering with another?
Yes. All three use the same water-based application method and soil moisture requirements, and they don't compete for the same hosts; each works a different layer of the soil profile.
Can I use Triple Blend alongside neem oil or insecticidal soap?
Yes, but timing matters. Apply nematodes a few days apart from any foliar spray, since some residue can affect nematode survival in the soil. The nematodes themselves pose no risk to your other treatments.
How often do I need to reapply?
It depends on the pest. Grubs, beetle larvae, weevils, borers, and most caterpillars run one generation per season, so a single well-timed application usually covers the vulnerable window. Ants, termites, fleas, fungus gnats, and a few other continuously reinvading pests need reapplication roughly every 3–4 weeks instead.
Is Triple Blend safe around edible plants, pets, and kids?
Yes. All three species are a natural biological treatment with no synthetic chemicals, safe around people, pets, and kids when applied as directed, and safe on edible crops with no waiting period before harvest.
How long until I see results?
Triple Blend starts working once it's in moist soil. It typically takes 5–7 days to see visible results through reduced pest populations.
Does this work in growing media besides soil?
Yes. All three species are effective in coco coir and peat moss, as long as the medium stays consistently moist.
I've heard nematodes can damage plants. Is that what this is?
No. That's a different, unrelated category: plant-parasitic nematodes (like root-knot nematodes) feed on roots and can genuinely harm a garden. The beneficial nematodes in the Triple Blend mix don't feed on plant tissue at all.
How do I know if a single species or combination is best?
