Indoor Plant Pests: How to Spot, Stop, and Prevent Common Infestations
When your indoor plant pests, tiny insects or mites that feed on houseplants and thrive in warm, dry indoor environments. Also known as houseplant bugs, they can turn your thriving greenery into a wilted mess in days. You might notice sticky leaves, yellow spots, or tiny webs—signs something’s wrong. Most people assume their plant just needs more water. But often, it’s not thirst—it’s an invasion.
Spider mites, microscopic arachnids that spin fine webs and suck sap from leaves. They love dry air, which is why they explode in winter when your heater’s running. Fungus gnats, small flying insects that lay eggs in damp potting soil. Their larvae eat roots, and you’ll see them buzzing around your plants after watering. Then there’s mealybugs, white, cottony bugs that cluster where leaves meet stems. They look harmless but can wipe out a succulent in weeks. And don’t forget aphids, soft-bodied green or black bugs that multiply fast and leave sticky residue. These aren’t just annoyances—they’re survival threats to your plants.
These pests don’t show up out of nowhere. They come in on new plants, through open windows, or even on your clothes after visiting a nursery. Once they’re in, they spread fast. The key isn’t just killing them—it’s breaking their cycle. That means checking new plants before bringing them home, isolating sick ones, and never letting soil stay soggy. You don’t need harsh chemicals. Simple fixes like neem oil sprays, sticky traps, or a strong water blast often do the trick. And if your plant’s struggling, it’s not always the pest—it’s the environment. Dry air? Poor airflow? Overwatering? Fix those first, and the pests lose their advantage.

You’ll find step-by-step guides on how to identify them, what actually works to kill them, and how to keep them from coming back.
