    I have been fighting these little white fuzzy bugs. Sometimes just one sometimes a whole cluster. I've looked up thrips and mealy bugs but they don't look exactly like those. I have all sorts of orchids but they are only on my Phals. Big ones and small ones. and mostly hybrids now that I think of it. They are 1 to 2 mm long. I have been wiping them off with q-tips and an alcohol and soap mix. Then spraying with neem oil. I clean them all off and the next morning I find some more. Does anyone know what these are and how to treat?
    I can post pictures tomorrow when they come back as I have already wiped them all off today.
    Thanks folks.

    if it is not mealybugs, then it well could be the young male scales. To be sure about this, A photo is needed.

    It may also be boisduval scale, which is white, but they don't come back that fast, nor does mealbug.

    Here's some pics this morning. Most were gone after yesterdays treatment with Alcohol and Soap and Neem oil.
    Still had a few lingerers.

    and here is a shot of an infloresense that was covered in bugs the other day. The crown of the seed pod was covered with them but I think they were all cleaned off. I just hope it didn't ruin the seeds. I think the other flower behind this one took also and I plan on pollinating this new flower.

    The first one is mealybug and the second one looks like boisduval scales(small round ones are female and the white little skinny ones are male). Repeat the treatment in a week and keep the eyes on them. Boisduval scale is not easy to get rid of.

    I found imidicloprid (in Bayer 3 in 1) was very effective against the boisduval scale, but my mealybug had an immunity after a while. A systemic is a good idea because both of these can be anywhere on the plants.

    If going into chemicals, alternate every 2-3 applications, or it'll develop resistance.

    You can go after with alcohol/soap every 2-3 days. No resistance or arthropodswould have to make a change to 500 million years cuticule habits. ;)

    If some (adult) bugs appeared the day after an alcool treatment, it's because it avoided it. You've got to stick to spray regularly.

    Have you repoted? Sprayed the roots? If not, you should.

    I found imidicloprid in the yard spray from Bayer. Neither store I went to had Bayer 3 in 1. They had Bayer Advanced with Carbaryl (1-napthyl N- methylcarbamate) It listed Apple mealy bug as one of the bugs it kills. I don't know if that's the same. I will try and get back to you all.

    It isn't usually the insecticides that damage plants, it is the carrier. I've not tried the Bayer Advanced on orchids, but many people use the Bayer 3-in-1 on their collections. It isn't uncommon. If you are using the other, try it on an orchid you wouldn't mind loosing before spraying on other things.

    If your collection isn't big, try Bayer Advanced (Dual Action) Rose & Flower Insect Killer. It is a ready to use product in a blue spray bottle and quite safe even for those sensitive plants, runs about $5.50 at Lowes or HD. It contains imidicloprid, a main ingredients of Merit(another systemic insecticide).

    Be careful with some of chemicals, like Merit/imidicloprid, some insects could develop the immunity if you keep using it for a long period of time, so rotating the chemicals is recommended.

    I sprayed the Bayer Advance with stated chemicals (above) on a plant that I could lose. Nothing has happened in 24 hrs. What is a good test period?

    You should not have problem with that Bayer product I mentioned ablove. Many people have used it. I only use them for my sensitive plants, like Lepanthes, Oxyglossum Dendrobium and few others that are sensitive to oil based chemicals. I would use it for all of my plants but my collection is way too big for just a little spray bottle, so I have to mix my own...

    As Tom says, no need to wait with this product.
