    I too have been battling thrips for several months now. At first I saw minute insects thrashing around on watering day. Progressed to seeing adults flying so I made several sticky traps out of pieces of thin plastic file folders with tanglefoot as the sticking medium. Stuff works great and all it takes is a thin layer. Then I bought a fine mesh "food umbrella" and sequesterd the "carrier" orchid. By the end of the first day I had recorded 10 adults stuck, 7 squished by me and one that got away to somewhere. Today, 3 days later the count is significantly lower so it seems to be working. The medium has been allowed to dry in the hopes it'll dessicate the presumed larvae and they will become fertilizer. Sticky traps are set up near the other orchids; so far there's no adults stuck to those. Time'll tell if this works but right now it's looking pretty good.

    Hello
    I have not made a comment or contribution in quite a while. No, I have not abandoned OT, just preoccupied with other activities. I do however, drop by to see what is going on here.
    I have been following this thread since I too have from time to time had to deal with Thrip infestations particularly in the hot and dry months.
    The last Post by SusanLee spoke about seeing the insects flying around. My experience dealing with Thrips is that they are so very very tiny that it is difficult to see them unless you take a damaged flower apart and take it into bright light in order to see them. Evidence of thrips is more easily identified by the damage they do to your flowers and hanging roots than by seeing them.
    I would like others to comment on this, or tell me I am wrong.

    Glad to see you are still around Angela and that you haven't forgotten about the forum. Hope your other activities are progressing well. PM'd you a couple of times but didn't get a reply so pleased to hear from you on the forum. The only creepies I used to be bothered with were mealies and scale -- plus the odd fungi. I cured all by giving the affected plants a dip in 5% chlorine bleach solution.--worked like magic and has never had any ill effects on the plants. Most orchidists are afraid to use this method but they shouldn't be it will cure 100%--------and it's cheap!!

    Hi Ed
    Thanks for your response. I have not used the Chlorine method, and would not be fearful in doing so since I use Physan 20 which I suspect is some sort of chlorine mix. I hear you that your method took care of mealy bugs and scale but I am not sure about this, since chlorine, to my best knowledge is more a Fungicide than an insecticide. If it works for you go for it.
    Sorry if I missed your mail. I was doing a bit of traveling June/ July, and was staying off the Internet. Hope all is well with you and Sheila .
    Regards
    Angela

    The 'chemical' I use is simply household bleach. I have tried Physan20 but haven't been excited with the results. Give the bleach a try --just put the whole plant into the mix ( about 2 tbls per gallon ) for about a minute or two and all the bugs will be gone. You can wash the plant with clean water after the dip.

    Hello
    I have managed to kill, with various methods, many of these small flying insects and have looked at them with an 8x magnifying loupe and they look exactly like thrips. I initially noticed small insects thrashing around when I watered the orchids and after straining the water through a very small mesh "cup" (one used to strain urine checking for kidney stones) and checking any debris under the loupe I found larvae which, again, looked just like thrip larvae. I made sticky traps and began to see small dark insects stuck to them. I put the infested orchids under a food umbrella (white) with a white towel underneath it: that is when I began to see these small dark insects flying around. The contrast between the stark white of the umbrella and the dark bodies of the thrips made them easy to see. Although they can disappear in a heartbeat. They are very small but it is still possible to see them flying around in this set up.

    So what's your method to get rid of thrips?!

    Best method worked for me is the sticky traps and continuous (weekly) use of neem oil + soap.
