How To Kill Insects In Houseplants

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.

How can I eradicate insects from my indoor plants?

These tiny, wingless insects, which when gathered together seem white, are typically found on plant stems, leaves, and nodes (the area where leaves meet the stem). According to Scott, “Mealybugs are drawn to excessive succulent growth, which can be brought on by overwatering and overfertilizing, particularly with fertilizers heavy in nitrogen.” Plant development slows down and leaves often curl and turn a faint shade of yellow as a result of their feeding on plant sap.

By delicately wiping them with a cotton swab dipped in 70% isopropyl alcohol (avoiding touching delicate leaves), or by misting them with a solution of dish detergent and water, you can get rid of the bothersome insects (one teaspoon of soap to one gallon of water). Mealybugs can also be controlled with insecticidal soap, neem oil, and horticultural oil. Follow a planned fertilizer schedule rather than indiscriminate feeding to stop breakouts, advises Scott. Mealybugs can easily be removed with your own hands if discovered in time.

How can bugs in potting soil be eliminated?

It’s crucial to get rid of any little, fuzzy gnats that are buzzing around your potted plants. Fungus gnats are bothersome, but it’s the larvae that feed on soil organic matter, including the roots of plants. One part hydrogen peroxide and four parts water are advised by Pistils Nursery. Incorporate the solution into the potting soil. Repeat as necessary at each watering to get rid of the eggs and larvae and get rid of the gnats.

Hydrogen peroxide treatment of soil and hydroponic solutions has also been discovered by growers to be effective in getting rid of root aphids. According to Weedmaps, hydrogen peroxide has had some success when used in conjunction with heat and cold treatments like heaters and water chillers. Exercise caution because severe heat and cold might harm some plants. Additionally, maintain good gardening hygiene by sanitizing spent containers, rotating your plants, and cleaning the hydroponic system and greenhouse.

Hydrogen peroxide therapy offers other advantages. Hydrogen peroxide, a potent oxygenator, decomposes and releases its oxygen into the soil. The roots of the plants receive oxygen and nutrients as a result. Additionally, it has a significant impact on bacteria and fungus, which are eliminated from the soil with every irrigation. Use a solution of one part hydrogen peroxide to two parts water to hydrate the plant and control the fungi that cause root rot, and then wait until the soil is almost completely dry before continuing light watering if overwatering is harming your plants.

How can bugs in plants be eliminated without causing plant death?

According to Jeff Gillman, author of “The Truth About Garden Remedies: What Works, What Doesn’t, and Why,” commercial insecticidal soaps are safer for plants than homemade equivalents. Keep it mild if you want to try producing your own. 2 teaspoons of liquid dishwashing soap combined with 1 quart of water yields a 1 percent soap solution. Use a mild dish soap made for hand-washing dishes, not laundry or dishwasher detergent. Aphids, mealybugs, mites, and other soft-bodied pests respond well to soap spray. Additionally, Gillman adds that dish soap aids in preventing powdery mildew.

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 I eradicate little insects from my plants?

We plant lovers don’t want to witness plants being harmed by pests. The problem enters our homes, which is gross, therefore we especially don’t want to see pests in our houseplants! The little winged creatures known as fungus gnats are about the size of fruit flies and resemble tiny mosquitoes (don’t worry, they don’t sting!). The good news is that these pests are considerably less dangerous than many others, and even better, they are rather simple to get rid of.

What are Fungus Gnats?

It’s probably a fungus gnat if you encounter a little winged bug that resembles a fruit fly fluttering about the soil of your houseplant. They are attracted to damp, nutrient-rich soils and have long legs for a fly their size. Your plants’ leaves have very little appeal to fungus gnats; instead, they prefer the damp earth beneath the plant canopy. They devour the hair roots of your plants and lay their eggs in the top layer of damp soil. Nothing is more impolite than an unwelcome guest laying eggs in your favorite plant and consuming its roots, even though their damage may be modest. These bugs eventually cause wilting, poor growth, and discolored leaves if left untreated.

Signs of Fungus Gnats

If you have a gnat infestation, you already know how noticeable they are. Due to their poor flight abilities, these flies usually stay rather near to the plant. They’ll be moving in zigzag patterns as you watch. Their tiny, transparent larvae could be visible if the dirt is carefully stirred. Yellow sticky cards are an excellent control method as well as a terrific way to keep track of their activity. See more below on that.

The Number One Way to Get Rid of Gnats

Infestations of fungus gnats typically occur when the soil is very damp. Problems might arise when plant parents provide the same care to their plants throughout the year. Consider this: Compared to the winter, our homes are typically brighter and more humid in the summer. In the winter, most plants become more dormant as a result of the changing seasons. You can keep fungus gnats from setting up camp in your plant pots by reducing the amount of water you use.

Gnats deposit their eggs in the top layer of the soil, and the soil must remain moist for the eggs to survive. It can harm the eggs and disrupt the gnats’ life cycle if you let it dry out. Your indoor plants should be soaked from below if your pot allows it. While the soil near the root ball absorbs water, the soil surface remains dry. Place the pot in a dish of water and let the water to seep up through the drainage holes to do this.

What If That Doesn’t Work?

You can intensify your treatment plan if you’ve modified your watering schedule and the gnats are still present or if you want to get rid of them quickly. Here are a few simple methods for getting rid of gnats in your indoor plants:

Apply sticky cards. In our greenhouse, you may have noticed the yellow cards on sticks and wondered what they were for. The cards are positioned directly above the soil’s surface since gnats prefer the color yellow. Checking what you’ve captured allows you to keep track of what you have while also getting rid of all the gnats that land on your credit card. Replace your sticky card every 4-6 weeks (or sooner if it’s bugged), just to be safe.

Larvae are quickly, inexpensively, and efficiently killed upon contact with hydrogen peroxide solution. Spray your soil with a solution made of four parts water to one part hydrogen peroxide.

Although unpleasant, fungus gnats can’t stand a chance against a plant parent with a game plan. To avoid these disgusting bugs, reduce your watering frequency throughout the winter and develop the habit of bottom-watering. You won’t regret it!

What natural cure gets rid of gnats in houseplants?

You can sprinkle some cinnamon on top of the soil while you’re waiting for diatomaceous earth to arrive or as soon as you realize you have fungus gnats. The cinnamon stops them from laying eggs and acts as a natural fungicide and irritant.

Ceylon cinnamon is what you want to use, not the common variety that most people already have at home.

Water with Mosquito Dunks/Bits

The wonder solution known as mosquito dunks will stop fungus gnats in their tracks and is also quite simple to use.

You simply need to place a small piece in your watering can and use it to water your plants. Additionally, each component will withstand numerous waterings.

These include the naturally occurring bacteria BTI as the active ingredient, which is poisonous to insect larvae like gnats and mosquitoes.

Toxins produced by the active substances only affect gnats, their larvae, blackflies, and mosquitoes. The gnat larvae are enticed to consume this rather than the fungus or roots because of this.

Hydrogen Peroxide Drench

Pour 4 parts water and 1 part hydrogen peroxide, 3 percent, over the soil of your plant.

The only effective method for eradicating the gnat population is to use hydrogen peroxide, which kills all fungus gnat larvae.

This dilute concoction has the ideal strength to kill insect eggs without harming your plant (it actually aerates the soil and cleans the roots).

Do not water your plant when it is already moist. Only do this when your plant genuinely needs water.

Use an Apple Cider Vinegar Mix

Killing out all of the eggs and larvae in the soil is crucial for getting rid of gnats in your houseplants.

After using the aforementioned techniques to accomplish that, you should catch every adult gnat that is still flying around to prevent them from laying more eggs.

Placing an apple cider concoction next to your problematic plant is one natural method for catching gnat insects. One teaspoon of sugar, two parts water, one part apple cider vinegar, and a few trace amounts of liquid dish soap should all be combined in a shallow dish (Blue Dawn is best).

Because apple cider vinegar is slightly sweeter than white vinegar and has an orange tint that also attracts pests, you must use it.

Use Yellow Sticky Traps

These sticky traps also work great if you don’t have apple cider vinegar or don’t want to deal with the vinegar scent. The gnats are drawn to them because they are yellow.

However, whether you employ the sticky traps or the apple cider vinegar approach, they only offer you a general idea of how terrible your gnat problem is. You must employ these techniques in addition to addressing the larvae issue.

Will vinegar eliminate pests on indoor plants?

For plants, vinegar works exceptionally well as a natural insecticide. Spray it over and under the leaves of the damaged plants after diluting it 1:1 with water in a spray bottle. Additionally, you can apply it inside the home to ward against bugs; the vinegary scent will vanish rapidly.

How can I eradicate little black flies from my houseplants?

A house plant purchase can be really thrilling! Whether you are adding to your indoor plant collection or buying your first indoor plant. It can change any space with its lovely foliage, shape, and brilliant colors. Unfortunately, little pests like fungus gnats and fruit flies can ruin our love and appreciation for our lovely houseplants. We are frequently frustrated by this, as is your houseplant.

Small flies called fungus gnats can be found buzzing around your indoor plant’s soil. Because of their sad biology, these small insects are drawn to indoor plants because they eat on outdoor plants. The good news is that you can get rid of them. The type of pests you have can vary depending on the houseplants you grow.

You must first determine what kind of pests are bothering you. Small black insects known as fungus gnats, which are frequently mistaken for fruit flies, are the most prevalent pests. The distinction is that fruit flies live around fruit, especially rotting fruit, but fungus gnats thrive in plants like succulents that have damp soil. These can harm your plant since they lay their eggs in the soil.

1. Add less water or dry soil Due to the fact that the majority of fungus gnats like to live in moist soil, laying a thick layer of dry soil on top of the bedding for indoor plants will allow the soil underneath to gradually dry out and keep the fungus gnats away. It should be mentioned that even though you may scare the flies away, depriving your houseplant of water for an extended length of time can harm it. For instance, cacti can tolerate dry soil, but other indoor plant species might not.

Another choice is to water less frequently. Because fungus gnats require a moist environment to exist, watering the plant less frequently and letting the soil dry out between waterings will make the fungus gnats uncomfortable and drive them away.

3. Think about Sticky Traps Fly sticky traps can be useful because they capture adult fungus gnats, stop them from laying eggs, and disrupt the life cycle. Place the sticky trap at soil level on or close to the damaged houseplant. Fly sticky tape is available online for purchase or DIY creation. Using a card, a yellow highlighter, a wooden stick, and Vaseline, draw attention to the stick, which will draw flies, then capture the fungus gnats with the Vaseline to end their life cycle.

4. Pesticide Soap or Spray Using insecticidal soap or spray, often known as horticulture soap, is a frequent option if the aforementioned approaches fail to successfully get rid of pests. You have the option of buying the soap online or at your neighborhood garden center, or you may create it yourself. When the sun has set and you have your horticultural soap, all you need to do is apply it to the leaves of your houseplant and the area surrounding it. This will prevent sunburn. This ought to discourage those bugs.

6. Pot up your indoor plants The best course of action is to sanitize your plant by removing contaminated dirt that has numerous eggs imbedded in the soil and repotting your houseplant in new and fresh soil without disturbing the roots if all else fails or the sticky traps are catching a lot of insects. For more information, see our tutorial on repotting your houseplant.

Congratulations, you’ve done all necessary to get rid of houseplant flies! The longevity of our cherished houseplants can be extended by removing these pests.
