How To Get Rid Of Pests On Houseplants

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.

How are pests on indoor plants treated?

These are the tiniest, pearshape insects that you have undoubtedly seen in the vegetable patch outside. They can be found on indoor plants as well, and they tend to congregate around developing leaves and flower buds. They produce a gooey fluid known as honeydew after sucking the plant’s sap.

Remove any areas of the plant that are seriously affected to get rid of the bugs. Use a damp cloth to remove insects from other places, or use the bathtub to spray them with water. A cotton swab dipped in rubbing alcohol, vegetable oil, or insecticidal soap can also be used to remove them. Weekly removal should continue until they are gone.

Why are the bugs on my house plants there?

I’ll address some of the most frequent inquiries I receive about fungus gnat control in houseplant soil in this section. Ask your query in the comments section if you can’t find the solution here.

Will treating the soil with hydrogen peroxide kill fungus gnats?

Hydrogen peroxide application to the soil may be effective in eliminating fungus gnats. Try moistening the top inch of the soil with a solution made by combining 1 part hydrogen peroxide to 4 parts water.

Pouring or spraying it on top are both acceptable options. Remember that the adult gnats that are flying around won’t be killed by this; only the larvae that are dwelling in the soil will.

Controlling the amount of water you provide indoor plants is the most crucial thing to keep in mind while trying to get rid of fungus gnats.

Keep in mind that fungus gnats like damp soil to breed, and that overwatering is the leading source of gnat infestations in indoor plants.

Even if you are successful in getting rid of a fungus gnat infestation in your home, further issues are challenging to stop. Fungus gnats are one of the houseplant pests that are easiest to manage, which is excellent news.

How can pests be removed from plants?

These pear-shaped, 1/6-inch insects puncture plant tissues to get sap. Without treatment, affected plants can have puckered leaves, display stunted development, and even perish. In addition, the aphids’ sweet, sticky honeydew attracts ants, who guard the aphids because they want the honeydew, and aids in the growth of sooty mold.

How to eliminate aphids

To get rid of aphids, spray plants vigorously with water, or cut off afflicted plant sections and eliminate them. Spraying with horticultural oil (a petroleum- or vegetable-based oil used to suffocate insects), insecticidal soap, or neem are examples of organic alternatives (insecticide made from a tropical tree by the same name). Aphid-eating lady beetles are another product you may purchase. Discover these other organic pest control methods.

How can indoor plants be kept pest-free?

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 survive in dry soil, you should wait to water your plants again until the soil 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.

Does vinegar eliminate gnats from indoor plants?

She asked me to write about a true issue she was having with her indoor plants. Of course! I bet many of you are struggling with the same issue.

Have you ever purchased houseplants for your home or office with the intention of bringing some nature indoors but noticed after a week or so that obtrusive small black flies are darting in and out of your line of sight with your computer screen? Ugh! You have a problem with fungus gnats!

Although fungus gnats resemble tiny mosquitoes or fruit flies, they are unrelated and do not bite. They can be spread by cut flowers, especially those with stale vase water, or even by plants with unsterilized soil (poinsettias can be the worst).

In moist plant soil, residential drains, and sewage areas, fungus gnats can be found. In wet soil, fungus gnats lay their eggs. Prior to developing into adult gnats and flying out of the plant soil onto your face, their larvae, which are only one-hundredth of an inch long, are almost impossible to notice. They eat plant roots, soil-borne leaves, and decomposing plant matter. It takes them around 10 days to grow. Indoors, they can reproduce all year long.

This issue is being exacerbated by the gentle care you provide your indoor plants, including watering them. The fungus gnats will like staying in your home if the soil of your houseplants is continually moist. The growing medium used for houseplants is another factor. Numerous potting mixture types contain components that hold onto moisture, and everything that promotes moisture also promotes fungus gnats. To avoid potential pests, Good Earth Plant Company only purchases from nurseries that pre-treat the soil.

So what can you do to combat these annoying little gnats? You must approach the issue from many angles.

Start by starting to wait longer between waterings for your indoor plants. One to two inches of the surface ought to be entirely dry. Sub-irrigation functions well for this reason, among others.

2. Make careful to get rid of any fallen or decomposing plant materials (leaves and roots) as these serve as fungus gnat larvae’s feeding sources. Place a few slices of uncooked potatoes on the surface of the soil to see if you have them. Take a look at the bottom after a few days. Are they chewed-looking? Your plants contain fungus gnat larvae.

3. You can cover the soil with a quarter- to-half-inch layer of diatomaceous earth or horticultural sand (NOT playground sand) to control the larvae. If you water it, the plant will dry out more quickly and fool the fungus gnats into thinking it is not a good site to lay eggs. Additionally, they are actually cut to death if they crawl across the DE.

4. Add one tablespoon of liquid dish soap and one teaspoon of white vinegar to the water every other time you water. The fungus gnat larvae will eventually perish as a result.

5. You can remove the plant from the pot, remove as much soil as you can without harming the plant, and then repot it to expedite the process. Place all of the used soil in a sealed bag and discard it. It cannot be applied elsewhere because doing so will just exacerbate the issue.

6. You can create organic traps on your own to get rid of the adult fungus gnats. You can pour a few drops of liquid dish soap to the bottom of a deep bowl after adding apple cider vinegar or red wine. Put it next to the infected indoor plants. The gnats adore it and will suffocate in it if they fall in. Every couple of days, replace it.

7. You can either buy or manufacture some sticky insect traps. Use cardboard pieces that are a vibrant yellow color, and cover them with Vaseline. For optimal effects, place them horizontally over your plants. Use a card holder from your florist, or one that comes with a plant. Put the card holder with the sticky trap inside, then affix it to your plant.

8. Some backyard gardeners fervently advocate adding three percent hydrogen peroxide directly to the soil of your plants. I wouldn’t advise this as your first option if you have a plant that is very priceless or sensitive.

It could be extremely difficult to entirely eradicate fungus gnats on your own if they frequently infest your plants, especially those in your office. In one instance, the gnats were entering through the ventilation system from another office, as I’ve seen!

We only utilize plants from reputable growers, and our experts take great care to prevent conditions from becoming such that fungus gnats can easily reproduce. We quickly remove any infected plants from our care (which doesn’t happen very often) to prevent fungus gnats from spreading to the rest of your plants.
