Now that it is warming up in Sydney, I have noticed some tiny flies in the soil of my pots. I think they are root flies.
They seem attracted to the pots containing rhizomes the most. These pots are in the shade and do not have mulch.
How do I get rid of these flies? I want to use what I am growing, so I need a solution that is safe later.
 My chilli seedlings are in the same approximate location. Most of these now have some mulch in the pots and do not seem to have many flies.
 My lemon grass sits in a nice sunny spot, has no mulch and is also looking OK.
Internet suggestions so far:
- Letting the top 2-3 inches of soil dry out.
- Placing brightly coloured cards coated in vasaline to lure and trap them.
- Placing cups of vinegar and water solution near your pots.
- Hot sauce water. The hotter the better.
- Vodka water. 1:1 ratio of vodka and water.
- Neem oil
Home made Vaseline traps were no good. Store bought sticky traps are more successful.
Hot sauce water did not work.
Vinegar water did not work.
Drying out the soil works for control. But today was a hot day and things are wilting so I had to cut my drying short.
