A few teaspoons of apple cider vinegar, a few drops of dish soap, and some sugar should be combined in a tiny saucer. Place the saucer next to the gnats. Use additional saucers if necessary. The delicious solution will entice the gnats, who will then fall in and become stuck. Until they are gone, frequently replace the solution.
Use Flypaper
To catch gnats, hang ribbons of sticky flypaper, but watch where you place them. Almost everything, including your curtains, hair, and furniture, will entice them to grip onto it. They should not be used outside because they will trap helpful animals.
Clean Drains
Pour a gallon of water and 1/2 cup of bleach into your drain slowly. After that, thoroughly rinse the drain with hot water. Follow the instructions on the label of a drain cleaning product if it is labeled for this type of insect control.
Set a Fruit Trap
Put a plastic-wrapped bowl with an overripe apple or banana in the kitchen. Make a couple of holes in the wrap. Any gnats that enter the bowl will be trapped, allowing you to get rid of them.
Gnats are a problem in my outdoor potted plants; what should I do?
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.
Why do my outdoor plants have gnats?
Once you are certain that you have gnats, you must do an inspection to find out where they are congregating and the extent of the infestation.
Gnats do not randomly appear in your garden or yard. Frequently, this is because they were attracted to your property by a fungus source, wetness, or rotting organic material because these are ideal locations for them to lay their eggs.
Inspect your garden and yard to determine where the gnats are congregating. Any wet location that is pulling them over could be from a plant that has contracted a fungal disease or another source.
Gnat adults or their larvae should be your target. Outside, you might find fungus gnats near dead leaves, rotting firewood, compost piles, and shaded locations with lots of mulch that may have received too much water. Look out for any decaying plants, fungus, or mold.
What eradicates gnats while sparing plants?
If you keep an infestation under control, fungus gnats normally won’t harm your plants, but they are very bothersome. They often fly directly into your face as they flutter around it. Additionally, they appear to follow you everywhere. It’s best to address their presence even when they don’t actually harm your plants because they are frequently indications of issues with your maintenance routine. Create a proper watering schedule.
Establish an appropriate watering routine
To eliminate any eggs or larva in the soil, establish a suitable watering schedule. Additionally, it will keep fungus gnats from settling there in the future. Before watering, always make sure the top few inches of soil are dry (for more common houseplants). A moisture meter is available, but I don’t bother with one.
You can print off my free printable plant watering trackers if you’re having trouble remembering when you last watered your plants. Every time you water your plants, update it on your fridge and laminate it!
Use sticky fly traps
In the gift guide I created the previous year for houseplant lovers, I featured my favorite yellow sticky stake fly traps. Since then, I’ve been purchasing inexpensive yellow fly paper, cutting it into strips, and affixing it to the stakes. or simply hang it up. These are quite effective at managing adult populations.
The yellow color of the fly traps attracts swarms of adult gnats. They perish after becoming entangled in the deadly yellow fly paper. Gnats, I’m sorry. And once adult numbers are under control, there is nothing on which to lay eggs.
Invest in a Katchy machine
Okay, I’ll confess it: after seeing one of my planty pals on Tiktok post about her Katchy, I went out and purchased one myself. I was struggling to handle a severe fungus gnat infestation at the time. I gave in and purchased it, and it’s actually pretty wonderful!
The advantage of the Katchy is that it actually has a very attractive appearance—much nicer than a bunch of garishly colored fly paper hanging all over your home. Additionally, you can rapidly replace the sticky fly traps to give it a fresh look.
You turn on the UV light that is mounted on top of it at night to attract flies to it. The flies are then drawn down onto the fly paper by the machine’s fan.
Get rid of gnats in houseplants with vinegar
A quick and easy method for reducing adult gnat populations is vinegar. In addition to sticky traps, this is a fantastic alternative. Simply add a few drops of dish soap to a small shallow bowl of vinegar. Refresh as it fills up with dead gnats every few days. They adore this material.
Use sand or gravel to dress the soil
Fungus gnats lay their eggs in the top few inches of soil, so covering the top with sand or gravel can assist to keep them out. I’ve done this with decorative pebbles or sand, but that’s not my preferred approach. However, I am aware that some people adore this approach. So it’s worthwhile to try.
Hydrogen peroxide mix
You most likely already have hydrogen peroxide in your home, which is another substance that can help control fungus gnats in addition to vinegar. When watering dry soil, use 1 part hydrogen peroxide with 5 parts water to help kill off any organisms. Almost all common houseplants won’t be harmed by this, just avoid using straight hydrogen peroxide!
Try a soap and water mixture
This was briefly discussed in my essay on how to debug plants before storing them for the winter. To get rid of everything in the soil, I usually put an insecticide on it and mix it with some soapy water.
I don’t give this much thought. I simply fill a watering can with warm water, a few drops of mild dish soap (one without a degreaser), and the soap. It will start to bubble. The plant is then given water. Simply sprinkle the top layer of soil if your plant is already damp to stop further overwatering.
Neem oil spray
You may also get rid of fungus gnats by using neem oil. Either get a diluted neem oil spray or a neem oil concentrate and make your own dilution. A concentration I purchase, I find, goes further. My own has been around for a while, and I simply reuse an old spray bottle.
Sprinkling cinnamon
Okay… I’ve tried it before, but I don’t think it had any effect. But a lot of folks suggest cinnamon. Cinnamon, a natural fungicide, can be sprinkled on top of the soil. This should be done while the earth is dry, worked into the top inch or two of soil, and then the plant should be watered.
Use a systemic pesticide
A systemic pesticide can also be used to eradicate everything in the soil. When you water the plant, the pesticide kills everything. You can apply insecticides to the top few inches of the soil. In all honesty, since fungus gnats are less difficult to eradicate than other pests, you probably don’t need this strength of insecticide on them.
I killed several thrips that I had in my giant monstera deliciosa and other indoor plants with insecticide granules. It succeeded! Praise be, it also wiped off all of the fungus gnats. Consequently, it was a plus!
Can vinegar be sprayed on plants?
The most popular application for household vinegar is as an organic weed killer. When used on those annoying, difficult-to-kill weeds, they will vanish in two to three days, but you must be cautious when spraying it around specific plants because it may be damaging to them. To complete the task, combine one gallon of white vinegar with a cup of salt and a few tablespoons of dish soap.
What outside deters gnats?
- Insect repellents include DEET, citronella, vanilla, pine oil, and dryer sheets. On your porch, you may also utilize fans to keep the air circulating and deter hovering swarms. The effectiveness or toxicity of the various repellent sprays, lanterns, and granules that are available on the market that claim to keep gnats away varies.
- Chemical controls: Gnats can be controlled with foggers, sprays, and pesticides made for flying insects, albeit they aren’t particularly efficient at avoiding more infestations. Chemical controls are less safe and less effective than prevention.
Your neighborhood garden center or online vendors like Planet Natural and Golden Harvest Organics have a selection of organic fungus gnat control items, including as predatory insects and repellents.
Contact your neighborhood agricultural extension office for recommendations tailored to your area if you’re unsure about the type of insect you’re dealing with or if you’re getting bitten.
What are the little flying insects that I have on my garden plants?
Gnats are a small group of invasive flying insects that can cause problems in your house and yard. They may potentially result in health issues and damage to vegetation.
How can I eradicate little black flies 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!
