I like what I read about pyrethrine and met52,but it seems they are very difficult to find them in my area.I will keep searching and trying some experimental methodes as well.
In the meantime,does anyone have a clue wheter elevated CO2 levels in the greenhouse would kill this pest? The greenhouse is not big so I could easily raise CO2 levels well above 1% for extended period,but would it actually do anything to them?
