What Are Houseplant Pests?
Houseplant pests are tiny bugs or mites that feed on the leaves, stems and/or roots. There are many different types of bugs that can infest indoor plants.
Some will crawl around on the leaves or in the soil, and some can fly. Others don’t appear to move at all, and look more like a fungus or disease.
Regardless of how they move around (or don’t move), they are all extremely annoying!
Wait, What? My Houseplants Have Bugs!?
I know, it seems really weird that a plant growing indoors can get infested with bugs, but it’s a very common problem.
Trust me, I’ve been growing houseplants most of my life, so I’ve dealt with my fair share of infestations.
It’s no fun. But, if you have houseplants, at some point you will probably have to deal with plant pests. It just goes with the territory.
Why Does My Indoor Plant Have Bugs?
Infestations are worse in the house than they are outside because there are no natural predators to control houseplant pests.
Though houseplants can be infested with bugs any time during the year, they are most vulnerable in the winter. Here’s why…
- Houseplants go into a state of dormancy during the winter, which can make them more prone to attacks from pests.
- Winter growth on a many houseplants is weaker than it is in the summer, making it more vulnerable to infestation.
- Humidity levels are much lower in the house during the winter, which is the perfect breeding ground for some types of plant bugs. Plus, your plants don’t get any fresh air.
Where Did These Plant Bugs Come From?
In order to get rid of bugs on houseplants, and keep them from coming back, it’s important to know where they came from in the first place.
Houseplant bugs are tiny and can seem to appear from nowhere, so how they got on your indoor plants is often a mystery.
Below I will list a few common ways a houseplant can become infested with bugs, but you can read all about where houseplant pests come from here.
- bags of potting soil
- new plants
- open windows and doors
- a plant that was outside
- fresh flowers or produce

Why You Should Use Natural Pesticides On Houseplants
I never recommend using synthetic chemical pesticides on plants. Not only are those toxic chemicals bad for our health, they don’t always work to kill plant bugs.
Over time, houseplant bugs can build up immunity to chemicals and become resistant to them. That’s why it’s important to use all-natural pest control methods.
It’s always best to know which pest your dealing with before you begin treating your plant so that you are sure to get rid of them as fast as possible.
But below are some general tips for getting rid of any kind of indoor plant insect, whether they are on the leaves, flying around the plant, or in the plants soil.

How To Get Rid Of Bugs In Houseplants Naturally
If you find any pests on houseplants, it’s important to act fast and begin treatment immediately!
You want to control houseplant pests as quickly as possible to prevent them from spreading to your other plants.
When it comes to pesticides, it’s always best to stick with natural methods and products.
All of the methods I recommend for controlling houseplant pests are all-natural products or home remedies, and they work great!
How To Get Rid Of Bugs On Indoor Plants Leaves
Most common houseplant bugs feed on plants, and will be found on the leaves, flower buds and/or the stems. Here are some tips for getting rid of bugs on indoor plants naturally…
1. Isolate the plant – The first thing to do is immediately isolate the plant to prevent the infestation from spreading to your other houseplants.
Also be sure to monitor the surrounding plants closely for signs of indoor plant pests for several weeks.
2. Clean surrounding area – Some bugs can leave the plant and hide for a long time.
So be sure to thoroughly clean the area where the plant was sitting using soapy water. You can also sterilize the area with rubbing alcohol if you want.
3. Wash plant leaves – Wash the infested plant with insecticidal soap, or use a mild liquid soap. Soap kills houseplant bugs on contact.
Be careful with the type you use though. Some contain degreasers and detergents that can harm sensitive plants.
Always spot-test any type of soap on your plants before washing all of the leaves.
4. Clean the pot – Wash the pot and plant tray with soapy water too. Houseplant pests can easily hid under the rim of the pot or tray, or even on the bottoms of them.
5. Remove the bugs – Use a cotton swab soaked in rubbing alcohol and dab it on the bugs to kill and remove them from the plant.
6. Treat the plant – Treat the plant with neem oil for long-term indoor plant pest control and prevention.
Neem oil is a natural insecticide for indoor plants that works to kill and repel bugs. You can learn all about how to use neem oil insecticide here.
Alternatively, you could use horticultural oil or try using a hot pepper spray.
How To Get Rid Of Tiny Flying Bugs On Houseplants
Most indoor plant insects fly at some point in their lifecycle, which makes them even more difficult to control.
But killing the flying bugs alone isn’t going to be enough to eliminate a houseplant pest infestation. You need to kill the eggs and nymphs in order to get rid of insects on indoor plants all together.
So be sure to follow the steps above for getting rid of bugs on plant leaves in addition to these steps. Here are a few additional tips for getting rid of flying houseplant pests…
1. Sticky Traps – Use yellow sticky traps or houseplant sticky stakes to capture and kill little flying bugs in houseplants. This will help to control them, is non-toxic, and can prevent them from flying to nearby plants too.
2. Vacuum cleaner – Suck the flying bugs up with the vacuum cleaner. This works well to get a large population of flying indoor plant pests under control quickly.
Just be careful not to suck up the plant leaves in the process.
How To Get Rid Of Bugs In Houseplants Soil
Many types of houseplant pests can be found in potting soil, especially fungus gnats. So any time you find bugs on your houseplants, be sure to check the soil too, and treat it if necessary.
Here are a few tips for how to get rid of bugs in the soil of houseplants…
1. Replace top layer of soil – Remove the top inch of soil and throw it out. Then replace it with fresh potting soil or a soil cover.
Using a soil cover like fine sand or a natural top dressing can help prevent a future infestation.
2. Use a soil drench – Drench the soil with an organic pesticide for houseplants. You could use an organic insecticidal soap (I make my own using 1 tsp mild liquid soap to 1 liter of water).
Or try a neem oil solution (which can work for systemic houseplant insect control). Be careful not to overwater your plant in the process though.
3. Water properly – Ensure you’re watering your houseplants properly, the soil should never be soggy. Wet soil is not only bad for houseplants, it’s a breeding ground for pests like fungus gnats.
If you struggle with watering, I recommend getting an inexpensive soil water meter to help you get it right.
4. Properly store unused soil – Store your unused potting soil in a bug-proof container, houseplant pests can’t live without air. I use a 5 gallon bucket with a tight fitting lid (this airtight seal lid is perfect).
How To Keep Bugs Out Of Indoor Plants For Good!
In order to get rid of houseplant pests, you must be vigilant in fighting them. You can’t just treat the plant one time and expect to kill all of the indoor plant insects, nymphs and eggs.
It can take several treatments to eliminate them for good. So once you start treating a plant, inspect it daily and continue treatment until all signs of the infestation are gone.
Most common houseplant pests multiply very quickly, and it takes several treatments to control them, and eventually get rid of them completely.
How To Prevent Bugs In Houseplants
Once you get rid of bugs on houseplants, you don’t want them to come back, right!? The best long-term defense against any houseplant infestation is preventive pest control.
So here are a few more tips for how to keep indoor plants pest free and healthy for the long run.
1. Never use dirty pots – Always clean and disinfect pots and plant trays before reusing them. You can wash them with soapy water or, if they are sturdy enough, run them through the dishwasher.
2. Monitor your plants – Check your plants on a regular basis for signs of indoor plant pests. I usually do this each time I water my plants.
3. Do not repot an infested plant – Never repot a plant just because it has a bug problem. Repotting can further stress an unhealthy houseplant, which could end up killing the plant.
4. Use sterile potting soil – Always use fresh, sterile commercial potting soil to repot plants – and never, never use garden soil!
If you’re repotting a houseplant that doesn’t have any bugs, it’s fine to reuse the soil in the new container for the same plant. But you should never reuse potting soil from one houseplant to repot another plant.
5. Inspect all new plants – Whenever you bring home a new plant, make sure that you inspect it closely for any signs of bugs.
It’s also good to isolate new houseplants for a few weeks to make sure no bugs show up.
6. Keep your tools clean – Sterilize your pruning shears and other tools every time you use them. You can wash them with soap and water, or dip them in rubbing alcohol between uses.
7. Wash your hands – Always wash your hands after handling an infested plant.
8. Debug outdoor plants – If you put any houseplants outside for the summer, be sure to debug them before bringing them back inside in the fall. Learn how to bring an outdoor plant inside without bugs here.
