Hi, A friend of mine with no internet is having a problem with his grow. He called me saying that he had little black bug thingies in the reservoir of his aero-system. This was a few days ago, we figured they must be something coming in through his intake hole which is in the floor and lets in air from under his house. Last night he said he saw a few in his other room where he has drip tables. Today he said he looked in his drip res and saw about 300 of them dead floating with all kinds of creepy crawlies in his hydroton, clear ones, white ones and black ones with wings. He dipped the pots in a solution of sm-90. I googled it for him and it appears that he has Fungus Gnats. From what I found online I told him to do this: Put up yellow sticky strips. Float some Mosquito dunks in his Reservoirs. Set out some red vinegar and beer in bowls. Get some goGnats, which is made for fungus gnats, and use it for a week if the mosquito dunks dont kill everything. Put some potato slices on his pots and change them once or twice a day (gnats will lay eggs in them, larva will bore into them). Clean up any and all dead plant materials laying around. Screen his intakes with screen door material. Does anyone else have any ideas on how to get rid of these buggers? His Aero grow is about three weeks into flower but his drip is still vegging. He is not against scorched earth policy if it doesnt poison the finished product. Upon finishing these crops he is going to do a complete sterilization of everything and fumigate like mad, in the meantime he needs to get rid of them as best as he can. Anyone?
