| Lisa,
Are you refering to fungal gnats? Also known as 'No-seeums' because of their
small size. If so, then they usually are attracted to decaying wood (bark) that
is usually moist. They will lay their eggs in the bark and although they are not
destructive to the plant itself, they are quite a nuisance. I use to water my
orchids in a mild dish washing detergent (dove) every time I watered for
2-3 waterings. This took care of them. Also keep up the air circulation and
inspect the medium to see if you see any of them. If the bark or moss is
old and/or decomposing, if the time is right, repot. I have been using worm
tea now for about 1 month and I can honestly say, I haven't seen a one
in any of my orchids. I hope this is the reason. |
