running co2?.crank it up to 5-10k ppm..be careful,5k ppm is the OSHA maximum "safe" level for humans.so BE CAREFUL,you pass out you die..good thing is you dont have to fill the whole room top to bottom,just the bottom half,and co2 is heavier than air,it sinks..so it will surround your plants in a suffocating blanket of doom...gas the fuckers for a day,wait 3 days,gas the new hatches..use any number of the oils/soaps/teas mentioned above,before,during,and after the gassings..to go the extra mile,do it a 3rd time..after you get rid of em,use neem oil regularly..its organic,and after 3 days is not found on the plants any more,you can use it daily with no ill effects..
