I have a houseful of nasty gnats that I am assuming came in with my plants from balcony to winter in my apt. I cannot get them under control. I am bedridden elderly widow + I have a 20 yr old Sr cat, so it cannot pose a health issue. I’ve the vinegar solution to no avail. Can you please help?
Fungus gnats are a problem this time of year. They are the result of keeping the soil too damp. Here’s a link to a very good article about the problem with solutions (including non-chemical) mentioned at the bottom of the article: http://extension.colostate.edu/topic-areas/insects/fungus-gnats-as-houseplant-and-indoor-pests-5-584/
