What i found to be a good way to slowing down and tring to eliminate
these pest are. STICKY BOARDS..that is baited.
I will be using them from now on in all my pots.
just as a prevention.
I found some laying around my store. Took some home put them
in my pots. A day or two later, I looked. I was Amazed of
how much stuff it caught. and also knocked gnat issue.
There looked like some dust on them, under a micro scope
they turned out to be some type of larvae. Gnat im assuming.
And its amazing how much more its trapping, putting a dent into
their life cycle.
So I take them out when I water, put them back in when im done.
SO If I was you.. Spray them down with some organic fruit veg stuff,
then get some sticky boards, that you can fold into a triangle and
place them in your pots..
Working like a charm for me
