Get Rid of Fungus Gnats:


What are fungus gnats? These pests are tiny, dark colored flies that look very similar to a fruit fly or mosquito. They are attracted to rich, moist soil – particularly with organic matter in it.

Adult pests only live up to a week, but in that time they can lay about 300 eggs.. yuck!

Are fungus gnats harmful to houseplants?

There are mixed responses about whether or not fungus gnats are harmful, but some sources say the larvae feed off the roots in the soil, which can lead to root rot. No thanks! Other signs your plant might be suffering from fungus gnats include sudden wilting and yellow leaves.

While they are not harmful to humans, I think I’d prefer not seeing a small cloud of bugs flying around my plant babies. So, how do you get rid of fungus gnats?


This is the easiest homemade pesticide recipe I’ve found on the internet, and it only has 2 ingredients:

1/4 cup apple cider vinegar

1 tsp dishwashing liquid

That’s it!

I found that those measurements don’t have to be exact. I usually do a splash of the vinegar and a few drops of dishwashing liquid.

What’s next?

Sit the bug trap among your houseplants to easily attract the pests. The sweet smell will draw them in, and they will drown once entering the trap.

You can get a trap full of dead bugs as quickly as overnight, but sometimes it can take up to a week for the trap to build up.


Set up a few of these bug traps and place them anywhere you see a dense presence of pests. Sometimes just one trap won’t be enough.
