Pesticide for Green House

[acapella]

Hi,

I have greenhouse cabinet in my house, all were seeming very well %80 humidity 22 - 24 celcius warm inside. All the orchids were doing fine with nice flowers.

Then a couple of weeks ago I have noticed very tiny flies flying inside - tried to catch them but still I catching one or two everyday, I am losing many flowers - I friend of mine told the reason for this are the files.

I am very upset - can anyone tell me how to get rid of the flies without harming my orchids.

Thank you in advance.

Hello acapella,

If the tiny flies are black, they are probably what is called fungus gnats. They do not damage flowers.

Could you explain more? Are you losing the entire plant, or just the flowers?

The plants are very fine, I am only losing the flowers, the flies seems grey not fully black

Different kinds of orchid flowers last different amounts of time. The flowers might be old and it might be their time to die. After you have 5 posts you can post a photo.
