How To Get Rid Of Insects In Houseplant Soil

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 Can I Naturally Get Rid of Bugs in the Soil of a House Plant?

  • Use a three percent hydrogen peroxide solution in water to thoroughly water the plants.
  • Add some diatomaceous earth to the soil’s surface and the saucer of the pot.
  • Put the plants somewhere well-ventilated, and let the soil dry up entirely.

What are the little insects that I find in the soil of my houseplants?

Many individuals have mistaken a fungus gnat infestation for a fruit fly infestation since fungus gnats and fruit flies have similar appearances.

They are not, however, the same kind of issue. In damp soil, fungus gnats deposit their eggs. When the eggs hatch, the larvae feed on fungus, tiny roots, and other organic matter in the soil. Fruit holds little appeal to them.

  • Fungus gnats are the tiny, black insects you may notice hovering around your plants and in the soil.
  • Fruit flies are the gnats that are buzzing about the fruit or the garbage disposal in your kitchen.

If you’re still unclear, read this article to learn how to distinguish between the two so you can always make a correct identification.

How is dirt sanitized?

Garden soil can be sterilised at home in a number of methods. They include of heating the soil in the oven or microwave as well as steaming (with or without a pressure cooker).

Sterilizing Soil with Steam

One of the finest methods for sterilizing potting soil is steaming, which should be carried out for at least 30 minutes or until the temperature reaches 180 degrees F. (82 C.). Using a pressure cooker or not, steaming is an option.

Pour several cups of water into the pressure cooker if you’re using one, and then set shallow pans of flat soil on top of the rack that are no deeper than 4 inches (10 cm). Wrap foil around each pan. Close the lid, but keep the steam valve slightly ajar so that it can eventually be shut and heated at 10 pounds of pressure for 15 to 30 minutes.

It should be noted that nitrate-rich soil or manure should never be sterilized under pressure because doing so could result in an explosive mixture.

If a pressure cooker is not being used, add about an inch (2.5 cm) of water to the sterilizing vessel before setting the soil-filled pans (wrapped in foil) on a rack over the water. Just enough of the lid should be left open to minimize pressure buildup as you close the cover and bring the pot to a boil. After the steam escapes, let it boil for an additional 30 minutes. After the earth has cooled, remove it (for both methods). Till you are ready to use it, leave the foil on.

Sterilizing Soil with an Oven

The oven can also be used to sterilize soil. Put some soil in an oven-safe container, such as a glass or metal baking pan, covered with foil, about 4 inches (10 cm) deep. Bake for at least 30 minutes, or until the soil temperature reaches 180 degrees F, with a meat (or candy) thermometer inserted in the center (82 C.). Anything above that can release poisons. Take out of the oven, let cool, and keep the foil in place until you’re ready to use it.

Sterilizing Soil with a Microwave

The microwave can also be used to sterilize soil. For the microwave, damp soil should be placed in clean, lidded quart-sized containers that are microwave-safe (no foil). On the lid, drill a few ventilation holes. For every few pounds, heat the soil for roughly 90 seconds at maximum output. Note: Larger microwaves typically have room for multiple containers. Before using, let these cool while covering the vent holes with tape.

A polypropylene bag can also be filled with 2 pounds (1 kg) of moist soil as an alternative. Place this in a microwave and leave the top open to allow for ventilation. 2 to 2 1/2 minutes of full power heating the soil (650 watt oven). Before removing the bag, seal it and give it time to cool.

Gnats in potted soil: how can I get rid of them?

Fortunately, there are several of organic and chemical-free ways to get rid of fungus gnats from your prized plants. You can use a traditional trap or common household goods like potatoes and dish soap!

Let the Soil Dry

It’s important to remember to let the soil dry out for a few days and refrain from watering your plant because fungus gnats and their larvae prefer to nest in moist soil. The gnats will be forced to live in an uninhabitable habitat as a result, and they will disappear in dry soil. Do not be afraid to skip your next watering in order to get rid of the gnats; your houseplant will be able to endure the dryness for a longer period of time than you might imagine.

The best advice is to take your plant out of the planter and drain any extra water from the bottom. Thus, there won’t be any dampness where gnats might deposit their eggs.

Use Traps

There are numerous traps you may employ to get rid of these bothersome bugs if you’re seeking for a speedier fix. You can choose to DIY these with a few common things or run to the store and buy specialist traps, depending on what best suits your needs.

  • Pour a cup of white vinegar and a few drops of liquid dish soap onto a shallow saucer. The gnats will be drawn to the solution and fall into the trap if you place the bowl near your plant. Repeat the procedure until no more gnats are present.
  • Sticky fly traps are an alternative if the smell of vinegar deters you from making your own homemade gnat trap. These little yellow paper sheets attract gnats and trap them with glue because of their brilliant hue. Although it might not be visually appealing, this procedure is simple and safe.
  • Consider purchasing an indoor fly-catching gadget if you’re sick and tired of gnats in your plants and need an urgent fix. These are typically USB-powered and can be purchased locally or online. The blowers and LED lights draw the gnats, and eventually they are drawn into the trap.
  • Are there any extra potatoes in the kitchen? Set a trap for them! Place the potatoes flesh-down on the ground after cutting them into little pieces. The fungus gnats will be drawn to the potatoes by their dampness. Just be careful that the parts don’t dry out otherwise it won’t operate.

Sanitize and Repot

Consider removing the plant from its planter and scraping out the soil if you want to take matters into your own hands. When doing this, take care not to disrupt the roots and take only what you can get rid of. Put the contaminated soil in a plastic bag and wash the planter with soap and warm water to sterilize it. Repot your plant into new soil after this is finished, then put it back into its planter.

Use a Spray Bottle

Take a spray bottle and combine water and dish soap in it. Repeat the technique until all of the gnats are gone by spraying the solution on the top layer of soil. If you’re seeking for a quick and natural solution to get rid of fungus gnats, try this.

Is it typical for dirt to include little bugs?

So you’ve run into an issue that I’ve experienced all too often: you’ve found some tiny, nimble bugs in your soil. What now?

Most likely, they are good to your plant; in fact, they are probably harmless.

You probably won’t want to keep them around if you’re an indoor gardener like I am, though.

However, I tend to discover them rather frequently on my indoor hydroponic gardens. There are a few different sorts of bugs that are frequently seen in indoor house plants. But first, we must pinpoint what they are in order to take appropriate action.

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.
