A fast, mobile beetle for heavy fungus gnat and root-zone pressure
When fungus gnats are heavy and you need faster knockdown than a soil mite provides, the rove beetle steps up. Dalotia coriaria, formerly Atheta coriaria, is a highly mobile soil-dwelling predator whose adults and larvae both attack fungus gnats, thrips pupae, shore flies, and root aphids. The winged adults fly pot to pot to spread themselves across the grow, establishing a self-sustaining population that keeps hunting without reintroduction.
Live insects ship on Tuesdays only and arrive Wednesday. Orders must be placed 7 days in advance. Anything ordered by 3pm EST Tuesday ships the following Tuesday by UPS overnight shipping.

Aggressive root-zone hunter Adults and larvae feed
Both the adult beetles and their larvae attack fungus gnat larvae, thrips pupae, shore flies, and root aphids, giving you fast, hard-hitting pressure on soil pests.
Spreads itself across the grow
The winged adults fly from pot to pot, so they distribute themselves through the room rather than staying only where you released them.
Self-sustaining once established
Adults lay eggs in the media and, once a population takes hold, it persists and keeps hunting without the need for repeat introductions.
Best for heavy infestations
Choose Dalotia over a soil mite when fungus gnat pressure is high or you need faster knockdown than a slow-building mite delivers.
Resilient and versatile
It performs well in greenhouses, nurseries, indoor grow rooms, and covered outdoor spaces, adapting to a range of growing setups.
Simple to apply
Sprinkle the beetles and carrier onto the media surface. There is nothing to mix and no equipment required.
Water the media about 10 minutes before release, then apply at sundown.
Distribute in small piles on the media surface, about 2 per m² (1 per 10 sq ft).
Keep the bottle horizontal before use, and release near fungus gnat hotspots.
Pairs well with Stratiolaelaps; one application per crop cycle is often enough if started early.
How the rove beetle clears a heavy gnat problem
Sprinkle onto the media
Distribute the beetles and carrier across the soil surface at the base of your plants.
Adults spread out
The winged beetles fly from pot to pot, spreading themselves across the grow room.
Both stages hunt
Adults and larvae feed on fungus gnat larvae, thrips pupae, and other root-zone pests near the surface.
Population sustains itself
Once established, the beetles reproduce in the media and keep hunting without another release.
