undefeatable fungus fly/sciarid fly
my indoor plants have been infested with fungus or sciarid fly since last summer. I bought some peat free compost from a well known home and garden chain to grow seeds and within a couple of days realised they had flies. Since then all my house plants became infested.
I tried hydrogen peroxide to no avail and then mosquito dunks for every water for several weeks. Eventually I threw out the most infested and repotted the others, just keeping the root ball.
I have less of the flies but I do still have them. I just found that my antihurium is still badly infested, another antihurium in my bathroom also seems to have a few flies. I am wondering if these are some sort of super strain or not even fungus flies, although they are not interested in vinegar traps so are not fruit flies. - any ideas any one?
