Hi, I know how your feeling about mealy bugs, I'v learned that if I mist my epies with soapy water it gets rid of them for a while. I'v use other stuff and it wasn't much better plus the cost of it I can't keep using it with all the epies I have. try using soapy water when you mist your plants and see if it helps, it won't cost you any thing to try and maybe it will help

I've tried the soapy water idea but it left a rather unsightly bloom over some of the plants and the bugs came back too quickly. I'm going to plant Tansy all around the area to see if that helps. Here's a link to a site that lists all sorts of other pest repelling plants if anyone else is interested. It will take time to get them all growing but I think it will be worth it in the long run. We'll see???

I get them occasionally, and they can be a pain to get rid of. Don't use any concoctions or chemicals, i use the ol' manual eradication and it works but in labor intensive. 1st I remove the plant from the old soil, then use a toothpick or skewer to break the fuzz barrier on each clump of bugs. Next I remove all foliage and plunge the whole plant in a trough of water and shake vigorously. Then I use the high pressure sprayer to get the last of the little buggers out of the crevices. Finally I repot into fresh soil and wait for the plant to recover.

Only thing I've found that works is to control the ants and increase air circulation with the greenhouse.
