    https://www.amazon.com/gp/product/B005OK9KRK/ref=o...If the link doesn't work, it's Sungro 5002 Better Bulb Orchid Grow Mix. The bark is medium sized. As I look at the bag, I do not a claim to be sterile. Not sure why that stuck in my head. It has worked well for my Cattleyas by itself. I added sphagnum to it for those orchids that never want to be dry. Again, before you spend lots of money and time, I strongly suggest you check out the American Orchid Society for suggestions. Much of its information is free but I decided to join this year and their video library has been helpful. Another suggestion is to get a picture of your pest and send it to your local Cooperative Extension. They can often identify bugs which could lead to a more useful Google search.

    I can't think of a way to sterilize bark while you're orchid is in it. I buy sterile bark off of Amazon and have not had any issues in the 5 years I've been doing this other than the fruit flies this past fall. You might need to bite the bullet and buy some fresh sterile bark and repot your plants. First consult the American Orchid Society website as well as they recommend treatments for disease and infestations. I opted to pay for a year's membership and their short videos have been worth the investment.

    Open on the sides. The plastic is exactly 4 feet long so rests nicely on the metal support bar. I recently set up a small rotating fan on the side to allow air movement through the system as a result. It still keeps the heat reasonably well.

    This happened to me last fall. I doubt they started in your orchids, but found their way there as it's a comfortable home. There are certain infestations that would be concerning, but if your plants look good, these guys are just hanging out there. I suspected mine were actually variations on fruit flies brought in on grapes, that liked my orchids. I made several fruit fly traps with balsamic vinegar. I placed them by the orchids for several weeks and gradually they disappeared. I would not rush to repot if your orchids are healthy. You could consider rinsing them really well, top to bottom, to remove any bugs. Then moving them into another closed room for several days as an experiment. If the insects are really laying eggs in the bark, they'll hatch quickly and they'll take over ag...

You could consider rinsing them really well, top to bottom, to remove any bugs. Then moving them into another closed room for several days as an experiment. If the insects are really laying eggs in the bark, they'll hatch quickly and they'll take over again. Repotting with sterile medium would make sense. If they're just hanging out like those on my orchids, they should be unable to follow. That suggests an insect trap has a good chance of working.
