What I use and has nullified the little fucks ....
Isopropyl alcohol 70%
Water
Few drops of plain dish soap.
I mix a 1:2 or 1:1 ratio of alcohol to water .. adding a few drops of dish soap to aid in blocking breathing and insects metabolism. By using a light soap mix ( drops ) you will not leave a residue. Alcohol will kill them on contact and evaporate quickly.
I pick up my pots ... tilting slightly and broad spray the undersides of
all leaf material including buds . While I turn pot to completely spray underside . Even webs on tops a
simple quick mist will kill them on contact. Even my flowering plants... it does nothing negative to the buds .
( you will be able to scope and see how quickly it works ) ..... I treat again after leaves have dried.
Even the little pearl eggs will be affected. I do this daily for 3-4 days as it takes about 4 days for eggs to hatch . I scope varies places on leaf to confirm effectiveness before next spraying .
You will see dehydrated adults and nymphs. The alcohol will penetrate the outer cuticle layer of the little shits and kill them on contact. Flowers can be quick sprayed ( mist ) and will not suffer . A bud wash ( dunk ) after harvest will remove the corpses . I have used various chemicals before and always use this
instead. It evaporates quickly and is safer than more common insecticides.
It will kill aphids , whiteflies , gnats also ....
