Root Maggots How do i Get rid of them.

I just realized I have root maggots in my soil grow, i have a few new clones, and few in veg and and 8 flowering. My new clones have root maggots. Second, They have already evolved into flies. So now they can contaminate everything. I need to get rid of them. Third, I am using mg organic choice, never really had a problem before for with it, but i am pretty sure this is where i got them from. What can I do. Is there something i can mix with my fertilizer solution to saturate the soil, along with a spray, and an organic spray i can spray on the flowering ones. Thanks

pyrethium spray or bomb for the flying ones , mosquito dunks for the water. you can buy both these at home depot.

how do i know if i have root maggots or springtails anyone know???

anyone know please help??

thats a new one on me, never heard of root maggots but thanks for the heads up. i also have been using mg potting soil. are your plants outside or in? could they have come from outside? good luck with that problem.
