    I'm currently having a terrible problem with flies that seem to be hatching from or being attracted to my newly watered orchids. Can anyone help me with some kind of natural fly "killer" that won't also kill my orchids?

    I think you have fungus gnuts. they say lets media dry up really well so the eggs dry and wont hatch. The reason you have them might be your plant have rotting roots or media maybe to old and broken down so it attracts gnuts. check roots and media, maybe repot in fresh media. Few people also suggest to get carnivorous plants and grow them around orchids. they do catch gnuts! but they can do only so and if you have many of them you have to think about other methods.

    I understand it is a 5 day incubation period for the fungus gnat. Let the media be dry for 6 days and that should cut them down, if not eradicate them. I don't have that many to be bothered by them. They don't harm orchids from what I understand.

    Thanks for the answers but I'm a bit confused. Does this GNAT actually look like a fly? They sure look like flies to me. Anyway, started using ready to use Neem spray on the surface of the media (where I can see what appear to be super tiny white eggs) and that has helped tremendously and, so far, I haven't seen any ill effects to the plants themselves. I will, however, start repotting all of them one at a time. Any comments?

    It does look like fly but much smaller, adult like 1/8 in.
    here is link for you. Adults are harmless for plants but larvae is not.

    I've checked and rechecked (especially on the sticky yellow strips we've recently hung right in front of our orchids) and they ALL look like common house flies. But, like I reported earlier, it appears that the application of the Neem spray, directly on the surface of the medium, appears to have done the job but future plans are to completely replace the medium in every orchid pot I have and, as soon as I can afford it, I'll do so all at once so there'll be leads chance of an infected pot reinfecting the newly changed out ones.

    Luckily my cat has no interest, and my dog is too distracted to even notice plants in the house. Sad to say it's my lumbering husband who usually knocks into my plants, even once or twice knocking them all onto the floor time for a more secure indoor location, like a full "walk-in" plastic greenhouse? :-D

    For the gnats, if I had a big issue, I would go with the Bti (Bacillus thuringiensis subspecies israelensis (Bti) (Gnatrol)), as described in Svetlana's link.

    sounds like thrips, which are in my orchids. I am trying to get rid of them as I read that they can be the cause of "bud blast" as well as doing damage to the roots. It appears this post is from 2012, 3 years ago. How are your orchids doing with their thrip population now, in 2015?
