Yes, potting soil can contain fungus gnats. Fungus gnats are very common in soils that have a lot of wood chips, are designated for outdoor use, or contain compost.
We're in an office with minimal plants and fungus gnats are all over. Where could they come from? Are they dangerous?
Mine are larger than fruit flies and I can't find them in plants, are they really fungus gnats?
I have a huge ficus plant and don't want to throw it away, what should I do?
Are these bugs also attracted to light? I thought we had fleas. Keep finding little black bugs appearing to hop however they also fly, we don't have any bites, and they are mostly near my house plants, and also I am finding them in the bathtub and bathroom sink. I want them gone.
Once the plant has been removed how long will it take to get rid of them?
