How To Remove Pests From House Plants

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 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 I eliminate pests without harming my plants?

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 are organic insecticides for indoor plants made?

When you are bitten by a mosquito, the itchy effects last for a few days before you may resume your normal activities. But when bugs come into contact with your prized indoor plants, the scenario can swiftly go from Zen garden to complete chaos. Fortunately, not all hope is lost when pests attempt to harm your young plants. You can produce a spray to kill everyone using just three basic materials.

All you actually need is some insecticidal soap to keep pests from taking over your healthy home (and your life!). According to Apartment Therapy, the nontoxic solution eliminates tiny, soft-bodied pests like mealybugs, aphids, spider mites, and whiteflies while also preventing them from destroying your prized plants. Although you may buy insecticidal soap, making your own is so simple that you might as well do it yourself and save a ton of money in the process.

All you need is water, 1 tablespoon liquid dish soap that doesn’t contain bleach, degreaser, synthetic colors, or scents, and 1/4 cup vegetable oil.

All you need is water, 1 tablespoon liquid dish soap that doesn’t contain bleach, degreaser, synthetic colors, or scents, and 1/4 cup vegetable oil. Simple, huh? Fill a spray bottle to the brim with warm water and shake the contents after adding the dish soap and vegetable oil. After that, you can spray the mixture directly onto your plants once a week until all of those pesky crawlies have been completely eradicated.

Japanese Beetle Prevention

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. Use one tablespoon of dish detergent, one cup of vegetable oil, one quart of water, and one cup of rubbing alcohol to make a fantastic homemade bug spray for vegetable plants. 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.

Tarnished Plant Bug Prevention

By keeping your garden clear of weeds throughout the spring, at least to the extent practicable, you can prevent attracting these bugs in the first place. By doing this, you’ll reduce the number of locations for bugs to hide and lessen their appeal to your garden. 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.

Flea Beetle Prevention

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.

Caterpillar Prevention

There are various techniques you might use to keep caterpillars away. The first step is to support native predators that will consume the caterpillars and eliminate them for you. Another approach is to mist the plants with a neem oil and water mixture.

Finally, you may attempt assembling a DIY chili spray. Blend three and a half ounces of dried chiles to produce this spray. Before adding half a gallon of cold water and a few drops of dish soap, add this powder to a half gallon of boiling water and let it boil for five minutes. Spray the caterpillars with this solution every morning until you stop seeing them.

How can I eradicate little insects from my indoor plants?

In most cases, only one plant is seriously affected, therefore Jason always tries to isolate it by placing it in a protected area outside.

It’s preferable to keep it separate from any other plants you may have outside, especially those in pots.

Invest in sticky traps or plants

Adult flying insects will be captured (and killed) by sticky traps or plants. Population growth may be slowed by the fact that one adult can produce up to 200 eggs.

For those who like plants, sundews (Drosera sp.) are a species of carnivorous plant that use their sticky leaves to entice tiny insects like fungus gnats.

Use neem oil spray

You can get a bottle of neem oil almost anywhere that sells plants. It is an organic insecticide manufactured from the seeds of neem trees.

It can be purchased as a pre-diluted spray bottle that is ready to use or as a concentrate that must be diluted in a spray container.

To get rid of the larvae, Jason advises misting the soil with diluted neem oil.

Spray your neem oil over the top 5 to 10 cm of the soil once a week for at least two months (or for one month after you stop seeing the flying adults). Remember to wait a day or two in between waterings when using neem oil outside of that.

It won’t harm your pets or eradicate helpful insects like earthworms, unlike many other insecticides.

Consider creating a soil barrier

Some people have also found success by topping their potting mix with small pebbles or horticultural sand (not the beach variety). This may hinder female fungus gnats from laying eggs in the ground.

Jason says he doesn’t like it because it can be challenging to see what’s happening in the soil, but to each his own!
