    Hi Susan,
    Here is what im doing for second week now.
    As soon as i spotted it i sprayed foliage with mix Sriram suggested. Im lucky to have neem oil (got it as sample for pesticide analysis). So i mixed 3 ml neem oil, 3 ml dishwash soap, 3ml 99.9% IPA (rubbing alcohol) in 1 litr water. So foliage got sprayed that all surfaces were covered. I spraed as much as i could bark too. Than i diluted that mix maybe have and soaked pots fo some time.
    There is no thrips on top part but next watering i did see some larvae in darined water. Some were alive. Im not sure if it was fungus gnut larvae or thrios though so i took it to work for entomologist to look he was quite busy on Friday so did not get back to me).
    Today and yesterday (gotta do it by step due to its too many had to be spraed) i sprayed mix again. And this time i soak pots in 1% bleach in water (40 ml houshold bleach in gallon). It was soaked probably for 5-10 min in this solution. When i take a look what is in it after i did see some larvae (in some pots more than in other, water after phals had more than after catts) but non of larvae was moving. So i guess its a good sign.

    HI Chemist
    Maybe the bleach solution I used was too weak? It was 2 tbls bleach per gallon of water. Haven't tried the neem oil. And the insecticidal soap didn't seem to do much. Am hoping that the IPA (is that short for isopropyl alcohol? If so, I like it ) has worked on the ones I used it on. So far, since the orchids were soaked, I've not seen any adults on the sticky traps. But the plants are still sequestered under the food umbrellas. Darn those thrips anyway!! I'm thinking they likely flew in through the screens on my windows this summer. It was so hot and dry here that the windows were open a lot! Anyway, hope your routine worked, and please be sure to let me know what the entomologist says!

    Yes, ipa is stands for isopropyl alcohol.
    So are you ready to know what entomologist said?!
    What i have im my drainage water is nothing to do with thrips or fungus gnuts. He said its springtails...
    He said its not good but not bad either. If you read on wiki pedia it says in some way they help to reduce fungi cause they eat it.
    I guess its bad when its too much in house than you have to call pest control.

    Whatever it is i will do one more treatment justbin case.

    And i agree thrips are annoying.

    I was watching a youtube video yesterday where a fellow was giving a tour of his orchid greenhouse. He has a plant in there but I didn't catch the name of it. It had thick yellow pads with tiny purple, kind of pretty, flowers. It was covered with dead gnats and other small flies. He said he never has trouble with fungus gnats due to this plant. The gnats (and I assume thrips) stick to the sticky, yellow pads. I'm not sure if it is okay to link to the video but I will if it is.

    I found the plant which is a Pinguicula or Butterwort. It's a carnivorous plant. It looks like it's a bit hard to care for but it does a good job of capturing small flies.

    I bought two plants you mentioned. First they were doing good but than their health declined to the point both died. I probably overwatered them. They did catched fungus gnuts, at that moment i did not have anything else.
    Care instructions for them says do not overfeed them, i wonder how to do it when you have bug problem LOL.

    Lucky you! No thrips. I'm pretty sure the little larvae I was seeing were thrips. They looked just like the photos and drawings that I finally dug up on the web. As did the adults flying around. And now they're DEAD! YAY! I did see some other strange wee creatures in the drained water. They were very small (could only see them with the 8X loupe) with long clear bodies with a brown streak (their intestines?) running down the middle and they had a little black nose. I never did find any illustrations or explanations as to what they could have been. I imagine the ipa mix killed them, too.

    May your orchids be pest free!

    ya know what, these insects I have been seeing might be fungus gnats after all! I just looked at a picture of one and, honestly, the bugs on my orchids look more like them than like thrips. So maybe I didn't have thrips after all!!
