I've noticed some tiny flies buzzing around my houseplants and I'm worried they're harming my plants. What are these pesky bugs, and what can I do to get rid of them for good?

Those tiny flies are likely fungus gnats, and the good news is they don't actually kill your plants. They're more of a nuisance than a serious threat. To manage them, you might want to consider using insecticidal soap to kill off the adults, but keep in mind that this won’t affect their eggs, so you’ll need to repeat the application a couple of times a week for a few weeks to really get a handle on them.
Yeah, identifying the flies can be tricky without a photo. Some tiny flies like aphids or thrips do suck sap and can harm your plants, but fungus gnats primarily feed on decomposing matter in the soil. If your plants are suffering, it could be due to overwatering or poor drainage rather than just those little flies. Make sure to let the top layer of soil dry out before watering again, as roots need air too! You can also use sticky traps for adult gnats and consider beneficial nematodes for the soil.
If you're dealing with fungus gnats, they might be annoying, but they won't kill your plants. A product like Gnatrol can help eliminate them in a couple of weeks; it’s pretty effective. Just make sure you keep the moisture levels in check – too much water can be worse for your plants than the gnats!
