Can Fungus Gnats Harm You or Your Houseplants?

Those little buzzing bugs are ‘bothersome’ to say the least. But, are they as harmful as they are annoying? Here’s what you need to know. 

Can Fungus Gnats harm people? 

The only thing they’re harming is your nerves! Fungus Gnats can’t bite and don’t spread diseases. They also don’t have a stinging tail, so put that mind at ease.

Are Fungus Gnats bad for plants? 

You’ll find a fair bit of conflicting info on this. The answer is “it depends”. The larvae of these gnats thrive in the moist topsoil of your houseplants, but in severe infestations, they can lurk deeper and deeper within the root system. If you’ve got a few here and there don’t fret, but if your house is buzzing, it could harm your plants.
