Pests that affect houseplants are a pain, and it seems like they appear much more frequently in the winter. This is due to the fact that our plants are weaker than they were at the height of summer, growing more slowly, and receiving less light.
Keeping your plants as healthy as you can is the best defense. Here are 9 suggestions for keeping pests away from indoor plants.
1) Avoid overwatering your indoor plants. For fungus gnats, moist soil that persists for a long time is the ideal habitat. These bothersome little insects, which are sometimes mistaken for fruit flies, won’t actually hurt your plants. However, they are unpleasant to look at and exceedingly distracting. Since their eggs and larvae cannot live in dry soil, you should wait to water your plants again until the earth is completely dry on top. Yellow sticky traps can also be used to catch as many adults as you can.
2) Check indoor plants frequently for pest activity. Winter months present a special insect risk for indoor plants, making caution even more crucial. In the winter, you might not need to water every plant once a week, but it’s still a good idea to pay close attention to your plants. Check in particular the areas where limbs meet the main stem and the undersides of leaves. Look for tiny spots on the leaves (various pests), fuzzy white lumps (mealybugs), spider webs (spider mites), or groups of small, firm bumps (scale). If you discover pest activity, you should quarantine the impacted plants right once and start treating the infestation right away. Look for wilting, mold or fungus forming on the soil, and leaves that are yellowing or have spots.
3) Place any fresh plants you bring home in quarantine to stop the spread of any pests. Okay, we get that occasionally you just can’t help but bring home a brand-new houseplant baby from the garden center. We have similar traits! Just remember to exercise caution when introducing new plants. Put them in quarantine for at least two weeks, ideally in a room without any other plants. Every few days, check them for pest activity.
4) Make sure there is adequate airflow for your indoor plants. Numerous bugs find stagnant air that is not moving to be a perfect habitat. In rooms with lots of plants, it’s a good idea to have a fan on to keep the air moving and help ward off bugs and mold.
5) Wash your plants every so often. A good spray down of all the leaves, tops and bottoms, stems, and the pot can help keep pests at bay. Giving your plants a shower with lukewarm water, whether in the sink or the shower itself, accomplishes two goals.
6) Clean and disinfect pots before adding fresh plants to them. When you are repotting, avoid moving plants into unclean containers. Make it a practice to either wash and bleach pots whenever you remove a plant from them or to make sure you have done so before you begin repotting your plant.
7) Increase the humidity, but only slightly. The majority of houseplants require between 40 and 60 percent humidity. The air in your home may become quite dry throughout the winter. If it does, think about placing a humidifier next to your indoor plants.
8) Remove any organic materials that is resting on top of the soil and clean up any fallen leaves. Pests thrive in conditions where damp leaves are lying on the ground.
9) The most crucial advice is to maintain the health of your plants, as robust and healthy plants are less likely to suffer from insect infestations. Look to see if your plants are:
- Having sufficient light
- During the growth season, receiving fertilizer
- in a saucepan of the proper size
- high-quality, draining potting soil was used for the planting
- Watered only when necessary.
Owning indoor plants nearly guarantees that you will experience a pest infestation at some point. However, you should be able to avoid pests on indoor plants if you try to keep your plants happy and healthy.
How can bugs in potted plants be removed?
When Acree returns home with a fresh plant, she immediately disposes of any pests by placing it in the bathtub. She tops the soil with pet- and kid-safe food-grade diatomaceous earth powder, which dries out the insects and their larvae, after lightly misting them with a natural DIY bug repellent that you can prepare with 1 tablespoon of tea tree oil and 1 cup of water.
Spray your plants
Making an insecticidal soap to spray on your plants is your best option if you’re dealing with soft-bodied pests like mealybugs, aphids, whiteflies, and spider mites. While you may purchase one at the shop, it’s simple to make a DIY version with organic ingredients. Simply combine 1 Tbsp liquid dish soap (free of bleach, degreaser, synthetic colours, and scents), 1/4 cup vegetable oil, and 1 Tbsp liquid dish soap in a spray bottle, then top it off with warm water and shake. Once a week, you can spray your plants with the combination to get rid of pest problems.
Dry out your plants
By simply eliminating the moisture, pests like fungus gnats that prefer damp soil in houseplants can be controlled. (Excuse me, gnats.) The best course of action in these types of circumstances, according to Susan Spanger, a professional gardener and floral designer at Bloomful Floral Design, is to water your plants less frequently than usual in order to let the top few inches of soil totally dry up.
You eliminate the source of food for fungus gnats—fungi in the soil—by not maintaining damp soil. The Sill claims that by letting it dry up, that important food source will be eliminated, which will also eliminate the fungus gnats. According to Spanger, you can also cover the top of your soil with a half-inch of sand. She claims that mature fungus gnats find the rough surface unpleasant and that it dries off soon. Those pests on the houseplants will never return.

Early in the morning, when the insects are least active, begin by shaking the insects off the plants. Spray down the plants with a homemade insecticidal soap once they have temporarily left.

Apply this spray in the morning for best effects, and be prepared to water the plants again if they begin to droop after the treatment.

But if you have a tarnished plant bug issue, find the nymphs and spray them with neem oil to get rid of it. Finally, encouraging natural predators of these insects is one of your greatest chances because they will do a large portion of your work for you.

Garlic-based products work well as natural insect repellents for flea beetles. A head of garlic, one tablespoon of dish soap without bleach, two tablespoons of vegetable oil, and two cups of water are the ingredients for this cure. Peel the garlic, then blend it with the water and oil to create the spray. Before straining the mixture, let it stand the following day. Add the soap and carefully combine. Simply pour it into a spray bottle after that, then use that to cover the diseased plants.
