Welcome!

Would you be able to post pictures (of the bugs and of the plants)? We need to confirm that they are gnats and that the damage is being done by the gnats Big Grin

Hi caitisonni, Welcome!

Fungus Gnats are usually present when potting medium is staying too moist. If you've revised your watering schedule you may need to allow the soil to dry even longer between watering. Adult gnats only live about a week but they lay their eggs in the upper surface of the soil and within a couple of days the eggs hatch, burrow into the soil and feed on damp, decaying plant material; a couple of weeks later they emerge as adults and the cycle continues. Keeping the soil on the dry side prevents recurrence.

Fungus gnats are super annoying but they are not much of a threat to your plants. Try putting sticky flypaper near soil level to trap the flying adults. It's not going to prevent them completely but it will make a huge difference in the numbers.

Yes, that is a fungus gnat. You can use sticky tape but if the soil of your plants continues to stay too wet, the gnats are likely to continue multiplying. I've also heard some say that they add a couple of drops of hydrogen peroxide to the water before watering plants which supposedly kills the gnat larvae in the soil but I don't know if it works or not.

Here's an on site articles with information about Fungus Gnats and other house plant pests and their control:
