Predatory rove beetle Atheta coriaria targets western flower thrips that build up in soil under greenhouse benches. Also attacks fungus gnats and shore flies.

2 beetles per plant once a week.

Recent reports indicate Atheta may occasionally scavenge for thrips inside the buds and become stuck in the bud resin. At this point, we suggest our other predators over Atheta unless you have used with prior experience of success or are using it with test plants.
