I have an outbreak of fungus gnats in my indoor plants. Some of these
plants are tomato, peppers, etc to be transplanted into the outdoor
garden. Other plants are houseplants. The cactus plants are not
infected, I think because these are watered once a month and the soil
is dry most of the time. What kinds of control (or better yet
elimination) are available that are safe and practical for indoor use
and for edible plants? I do not have any pets nor children. TIA
I have tried the cinnamon trick, learnd from an earlier post in this
newsgroup, and I can firmly attest it has no impact on my gnats whatsoever.
They happily crawl all over even a thick layer of cinnamon, and their
population seems to be as healthy and large as ever.
Maybe yor gnats are a different species.
I've taken our cinnamon trick to another level. After Henriette's
suggestion about using chamomile, I found a reference that suggested
using crushed garlic cloves in the tea, so I have added that to the
I apply it with my sprayer, with which I water.
I haven't seen a speck of fungus, mold, mildew, or gnats. Haven't lost
a single seedling.
It smells kinda funky though, especially when you add fish emulsion to
the mix for the transplants.
I have seen great numbers of gnats on what I thought was fruiting bodies of
Armillaria Root Rots 3 years after tree was cut.
Here is an article on Armillaria Root Rots.
