hmmm! I guess neem oil and CO2 usage might be the only possible legal solutions for me. I might either try this old bottle first and if it doesn't work...try a new one. I might also try buying some solid C02 and try it out. lol! What the heck? might as well do what I can. I just sprayed the ceph down with water. I never spray water on the ceph...it grows in pretty low humidity.
HEy!! would u think fresh squeezed lemon juice might help? lol! I use green neem lemons in a lot of foods that i make for garnish. It gives quite a distinct and nice tangy taste. Ofcourse..its citric acid IIRC. I would assume insects won't like it. Neem oil although is probably from bark of the tree or its leaves.
