Thrip vs Nematode

[Rothrock42]

I picked up a "Million nematode sponge" at the hydroponic/marijuana grow store (I live in Oregon). They are marketed for normal plants. Evidently you wring out the sponge in a gallon of water and then use the water to spray or soak into the soil and the nematodes feed on the eggs and larva of the thrips.

Anybody ever try this with orchids? Does the bark media provide a happy nematode home? What about LECA?

I'm also looking at imacloprid, pyrethrin, spinosad, and sns-209.

ummm...just asking for a friend.

EDIT: Found some additional information. The sponge has two different species, Steinernema carpocapsae and Heterorhabditis heliothedis. It says they do better if the soil doesn't dry out, so actually SH might be good.
