I have a rectangular pot with soil where I have attempted to grow peas.
For some reason (I'm not fully certain, probably over-watering) that pot became a breeding ground for fruit flies.
I have read the posts about getting rid of the flies in general (traps etc..) but this isn't enough - I need to get rid of the flies breeding in the pot.
What can be done, that would hopefully not harm the soil or the pea plants?
I have tried:
Various traps around the pot. They attract and trap flies, but more breed
Drying out the pot and not watering. Didn't seem to help much
Covering soil with small aquarium gravel (as per advice of someone I know). I don't think that helped at all.
