Hey all, so I just ordered a pound of Gnatrol granules from Valent. I called and asked if they knew if it affects the beneficial bacterias etc in the soil when you use this stuff and they claimed that it didn't harm any of the beneficial microorganisms in the soil, only kills the gnat larvae. Does anybody on here have any tips for using this stuff, anybody ran into any problems with it that i should be aware of? THank you.
