Neem does traps I leave the cover over bottom if needing to place on soil. I grow organically so the rhizosphere is a priority to me. One or two neem soil drenches if infested will not effect the outcome more so than the baby gnats eating plants roots. After neem you can always water with mycorrhizae and other means to help put microbes back in or help stabilize after the neem. Personally I've never noticed it or used neem enough to see a difference caused by using neem.
not the microbial life but the higher life forms are the ones getting decimated by the neem. i dont use any bottled products in my organics just homemade ewc and thats where the hypoaspis comes from. they get stuck on the traps and die off because of the oils used in neem suspensions. de kills them too. so i chose to keep my higher life forms happy to balance out the soil and whatnot. hypoaspis eats every little gnat larvae plus any other larvae or egg in the soil.
