What are Fungus Gnats?
Fungus gnats are small black flying bugs, somewhere between a fruit fly and a small mosquito in size. Some may mistake fungus gnats for fruit flies, but whereas fruit flies are generally found around your food, fungus gnats are found on the surface of the soil or around your plants.
What do Fungus Gnats do to Plants?
While it is lovely to have a house bursting with plants, having a house bursting with fungus gnats is not! Unfortunately these pesky little bugs are a common problem on indoor plants. While the mature fungus gnats do not bite or harm plants they can be annoying and unpleasant to have in your home. Fungus gnat larvae on the other hand live in the top inch of your plant's soil and feed on the tender roots, causing harm to your plants. Young plants are especially vulnerable to fungus gnat damage because they have not yet developed a strong root support system.
The good news is there are a number of ways to get rid of fungus gnats! Choose a few of these methods to try. A multi-pronged approach will be most effective!

How to Get Rid of Fungus Gnats
1. Sticky Paper for Fungus Gnats
Sticky paper meant for catching flies and bugs gives you a quick and easy start to controlling and managing mature fungus gnats. Keep in mind you will still need to treat the gnat larvae in the soil. I like to cut 1 in. x 1.5 in. pieces of sticky paper and lay them on top of the soil in my house plants. That way I can keep an eye out for any fungus gnat infestations and know what plants are affected. I purchased this 50 sheet pack of sticky paper from Amazon. I think I will have enough to last me years!
