Triple Blend Nematodes for Broad-Spectrum Soil Pest Control
Three Species. One Goal: Wipe Out Soil Pests.
This Triple Blend combines three powerhouse species of beneficial nematodes—Steinernema feltiae, Heterorhabditis bacteriophora, and Steinernema carpocapsae—to hit soil pests at every level.
Each species brings its own specialty:
-
S. feltiae targets fungus gnat larvae, thrips pupae, and shore flies in the upper soil layer
-
H. bacteriophora dives deep to attack grubs, root weevils, and other root-feeders
-
S. carpocapsae dominates the topsoil—ideal for cutworms, armyworms, and borers
Together, they provide broad-spectrum, biological pest control across multiple life stages—eggs, larvae, and pupae.
Targets:
-
Fungus gnat larvae
-
Root weevils
-
Grubs (Japanese beetles, June bugs)
-
Thrips pupae
-
Cutworms, armyworms
-
Fruit flies, borers, and over 200+ soil-dwelling pest species
See full pest chart for detailed coverage.
