Mealybugs, HELP
This is interesting, just yesterday I found a small Dendrobium & saw a
couple of mealies in the crevice of the leaves. I literally poured neat alcohol on them & they turned black immediately. This morning I went to check & there is more white stuff over the black residue? It's time for the big guns. -- Cheers Wendy Remove PETERPAN for email reply "Rob Halgren" wrote in message ...

Checked back and hour later, and the little sucker had wandered to a different part of the leaf. Still alive. So I tried the alcohol on the end of a Qtip, and checked back an hour later, it was still alive. Im doing this in my basement, so I dont want to use anything too toxic. Does anyone have an idea what will kill these critters? I want something I can spray, and not hurt me or the plants. I appreciate any ideas you all might have. Thanks in advance You put 70% isopropyl alcohol directly on a mealybug and it lived? Superbug!! I don't think that is possible. If you tried some other kind of alcohol (ethanol), then maybe. Make sure you are using rubbing alcohol straight out of the bottle. You can spray that on the plant, which you should do after you do the Q-tip routine. I promise there are more that you can't see. They love to hide in the base of leaves, and some hide in the potting mix too. Best to spray every four or 5 days for a few weeks, just to make sure you get them all. Even if you don't see any, spray anyway. So, why so gentle, anyway? You can squish mealybugs... I wouldn't bother putting anything on a q-tip to kill one, I'd just squish it. You can probably even squish it with a q-tip, or a pencil eraser, or something, if you don't want to get bug guts on your fingers.
