What To Use On Houseplants For Bugs

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 I keep pests away from my indoor plants?

You don’t want pests on your houseplants to reappear after you get rid of them, right? Preventive pest treatment is the strongest long-term defense against any infestation of indoor plants.

So here are a few more suggestions for long-term pest-free and healthy care of indoor plants.

1. Never utilize soiled pots

Before using pots or plant trays again, always clean and sanitize them. They can be cleaned in the dishwasher or, if they are sturdy enough, in soapy water.

2. Keep tabs on your plants

Regularly check your plants for indications of indoor plant pests. Every time I give my plants water, I typically do this.

3. Avoid repotting an infected plant.

Never repot a plant only due to a bug issue. An unwell houseplant may get even more stressed after repotting, which may cause the plant’s death.

4. Use clean potting soil.

Never, ever use garden soil when repotting plants; always use brand-new, sterile commercial potting soil! Reusing the soil in the new container for the same plant when repotting a houseplant that is pest-free is OK. However, you should never repot a plant using the same potting soil from another houseplant.

5. Examine all brand-new plants

Make sure to carefully examine any fresh plants you bring home for any indications of bugs. To make sure no bugs appear, it’s also a good idea to quarantine new houseplants for a few weeks.

6. Keep your equipment tidy

Every time you use your pruning shears and other tools, sterilize them. Between uses, you can wash them with soap and water or soak them in rubbing alcohol.

What type of insecticide is safe for indoor plants?

You can try a number of the cures listed below. Some methods will be more effective than others depending on the pest and the extent of the infestation.

In order to select the most effective technique of eradication, it is therefore best to be aware of the sort of houseplant insect you are dealing with.

Additionally, you could discover that it’s better to combine a number of these techniques. So make sure to try out the various treatments.

Whatever option you select, you must stick with it. An infestation cannot be eliminated with just one or two treatments. It can require some time.

Soapy Water

On touch, soap kills insects. Making your own homemade natural insecticide for houseplants is simple. One teaspoon of mild liquid soap to one liter of water is the ratio I use to make my DIY bug spray.

Use it as a spray bottle or to wash the leaves of plants that are severely affected (try the combination first on a leaf to ensure the plant is not allergic to it).

A fantastic natural insecticide for indoor plants is organic insecticidal soap.

Rubbing Alcohol

Insect pests can be killed and eliminated from the plant using a cotton swab bathed in rubbing alcohol.

While somewhat laborious, this method is excellent for getting rid of big swarms of pests like aphids, scale, or mealybugs from a plant.

Neem Oil

As a natural pesticide for indoor plants, organic neem oil is particularly efficient at eradicating and controlling common houseplant pests.

Additionally, unlike other treatments, it has a lasting effect, so you don’t need to treat the plant daily.

I strongly advise purchasing some if you experience recurrent infestations. Find out how to use neem oil as a natural insecticide here.

Soil Covers

To control fungus gnats, topdress the soil of an affected houseplant with a gnat barrier or try sand.

Diatomaceous earth applied to the soil’s surface could aid in the management of pests that dwell and reproduce in soil used for indoor plants, such as fungus gnats.

Yellow Sticky Traps

Yellow sticky traps are cheap, non-toxic, and very effective at catching flying adult houseplant pests like aphids, whiteflies, and fungus gnats.

Any infestation of houseplant pests will require a number of treatments, so persistence is essential. Until the infestation is under control, treat a houseplant for pests as soon as you notice any signs of them. Do not lose hope; we can prevail and keep our indoor plants naturally pest-free.

Is vinegar safe to spray on houseplants?

According to the Alley Cat Allies website, white vinegar has a potent, repulsive smell and taste that can effectively keep cats away from sections of your home that you don’t want them to enter. Despite being harmless to humans and cats, vinegar is deadly to plants due to its 5% acetic acid content. According to the Northwest Center for Alternatives to Pesticides, spraying vinegar on houseplant leaves will damage their cell membranes. As a result, the leaves are destroyed, and if the vinegar seeps into the plant’s soil, it will kill it by drying up the roots.

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.

Can Dawn dish soap be sprayed on plants?

Plants may tolerate a modest amount of Dawn dish soap diluted with water. It does contain compounds that, when applied in excessive quantities, can be abrasive and injure plants. I would also advise selecting a Dawn type with little fragrance or cleaning chemicals. You need soap that is as pure as possible.

You may eliminate the bugs that afflict your plants with Dawn dish soap, but you must use it carefully. If you use too much, the cuticle, a waxy layer on the leaf, can fall off and be poisonous to the plant.

The absence of the cuticle causes the plant to become dry and more susceptible to disease and pests due to the removal of the protective coat. Furthermore, the soap can stay in the soil, making it poisonous and lethal to any other plants.

Utilizing horticulture soaps created especially for plants is significantly safer because they are secure. These soaps are made to eliminate pests without harming the plant’s leaves.

I’ve included a list of Dawn dish soap variations below, along with which ones you can use on your plants.

How can I eradicate little flies from my potted 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! Fungus gnats are pesky, winged insects with little wings that resemble mosquitoes and are about the size of fruit flies. The good news is that compared to many other pests, these plant flies cause significantly less harm, and even better, they’re rather simple to get rid of.

Long legs, transparent wings, and a preference for nutrient-rich, damp soils are characteristics of fungus gnats. These little flies may be seen flying around plant containers, but unlike some more dangerous pests, you won’t observe them actually chewing on the plant’s foliage. However, you will see them in the soil, feeding on the organic matter and hairs from plant roots. Do not underestimate the damage that these bugs can still do if not addressed.

Even though adult fungus gnats only live for about a week, they can have a big impact in that short time by producing up to 300 eggs under the correct circumstances. With such a quick turnaround and a brief life cycle of about 3–4 weeks, populations can grow incredibly quickly.

It’s rather simple to tell if your plant has a fungus gnat issue. Since these plant flies can’t fly very well, they usually stay rather near to the plant. They’ll probably be moving in zigzag patterns while you watch them. It’s typical to witness all the different phases of this bug at once because they reproduce so quickly. It’s likely that some bugs still in their larval stage will be visible if you gently agitate the soil. They inhabit the earth where they eat organic debris and have translucent bodies and glossy, black heads.

Our plants are getting ready to settle in for the upcoming cold season as winter approaches here in North Dakota. Unfortunately, that signals that these pesky bug populations are about to reach their peak. During this time, dormant plants use less water, which causes their soil to stay moist for longer. Gnats thrive in moist soils because they promote root rot and fungus. Be cautious when bringing delicate plants inside to overwinter since you run the risk of inviting unwelcome pests into your house.

Your plants will start to exhibit signs of stress if ignored and neglected. Fungus gnats don’t directly harm plant leaves, but they eat the root hairs and deplete the soil of vital minerals. This may result in abrupt plant withering and yellowing of the leaves, sluggish development, and a general decline in vigor.

When tackling any pest, you should always start with natural management approaches. The least hazardous and disruptive to your plant and house are typically natural and organic remedies, while chemicals may occasionally be required as a second line of defense. Fortunately, most fungus gnat populations may be controlled and eliminated naturally provided they are discovered and dealt with in a timely manner. Remember that one plant container can hold three to four generations of bugs, so you’ll probably need to apply your favorite approach more than once. Gnats in your indoor plants can be managed in the following ways:

Do not overwater. Before watering your indoor plants, allow the top couple of inches of soil to dry up. This will not only stop fungus gnats from deciding that your plant would make the best place for them to live, but it will also interfere with their reproductive cycle and assist to reduce populations that have already moved in.

Activate sticky traps. Not just for mice, either! Sticky traps are easy fixes for many pest issues. Gnats that are moving will be caught if you place them immediately on the soil’s surface. To stop them from laying eggs, remove them from the trap, discard them, and replace it frequently (every two to three days). Particularly effective at drawing these insects, yellow traps are.

Create vinegar and cider traps.

Mix equal volumes of cider and vinegar in a shallow dish or can to act as a trap for fruit flies. Lay the trap on the soil surface inside the container or even next to the damaged plant. The concoction will attract the bugs, who will then fall into it and drown.

Bring in useful nematodes. Although it may seem counterproductive to introduce additional bugs into the equation, doing so is a simple way to reduce pest numbers. Nematodes are incredibly minute, worm-like insects that are frequently invisible to the unaided eye. In their larval stage, they attempt to infiltrate fungus gnats and other insects, releasing a bacteria that eventually consumes the pest from the inside out. When you think about it, it’s awful and disgusting, but not as disgusting as allowing gnats to devour your prized houseplants!

If all else fails, there are always insecticidal goods and sprays to keep pest numbers under control. There are many products available that either target the adult stage or the larval stage, but either is OK. You should be able to get rid of these unpleasant plant flies in a few of weeks as long as you successfully target one phase of their life cycle and reapply often.

Larvae are easily eliminated with hydrogen peroxide since it kills them immediately upon contact. Infuse your soil with a solution made of four parts water and one part hydrogen peroxide.

To destroy larvae, neem oil can also be put to the soil after being diluted with water. Neem oil can also be sprayed on surfaces to instantly kill adult flies. Last but not least, pyrethrin sprays contain extracts that are harmful to a variety of pests and can instantly kill flies and fungus gnat larvae.

Fungus gnats can affect the health of your houseplants even though they don’t transmit any diseases that are dangerous to humans. Your plants will thank you by giving off a lush, healthy appearance to enliven your home if you keep pests at away.
