Steinernema feltiae

Type

Entomopathogenic nematode

Target pests

• Sciarid flies

Notes

Applied as a drench; excellent for fungus gnat larvae control.

IPM positioning

Soil entomopathogenic nematode; applied curatively against sciarid larvae and soil thrips stages.

Best deployment strategy

• Apply as a curative soil drench when sciarid larvae or soil thrips stages are present.
• Ensure good irrigation before and after to keep substrate uniformly moist.
• Avoid tank mixes that harm living organisms; apply via clean lines where possible.

Compatibility notes

• Works well with: Stratiolaelaps scimitus / Atheta coriaria (predators provide continuity; nematodes provide curative reduction).
• Avoid: practices that dry the substrate rapidly after application.

Environmental preferences

• Highly dependent on substrate moisture: keep evenly moist before/after application.
• Performs best in moderate temperatures; very hot/cold conditions reduce efficacy.
• Avoid UV/desiccation during application.
