alcohol can be used to treat mealy bugs or aphids, but they tend to bounce back again with this treatment...

I use isopropyl alcohol liberally, and it works well. I do not know about denatured alcohol (which, if two decades old organic chemistry is recalled correctly is ethanol + a bit of benzene to make it toxic). I think isopropanol is the way to go, however.

I have been using isopropyl alcohol since the fall and seems to be working very well. As a matter of fact, used it on my Oncidium totosauri (ready to bloom) when the mealys were being pesty and the plant was apparently sick; use it every 2 weeks or so works wonders. I use a small bottle of alcohol and water and mist the infested area as well as a cotton swab the day after.

I also use isopropyl alcohol has a spot pest spray, and it works great for evening search and destroy missions for slugs. It's easy to work with and not as toxic as chemicals I use for bigger troubles.

I use 8oz alcohol 16oz water 1or2oz 409 or Dawn. The detergent helps the alcohol stick to the plant. Jim.

I also use isopropyl alcohol plus I ad a little dishwasher soap so that it sticks to the bugs better. It seems to be working great for me. I use a two or three drops of soap and like a tea spoon of alcohol to about a half liter of water.
