Fungus Gnat Traps – 2022 Market Overview

One of the most common methods for killing fungus gnats is a gnat trap. Gnat traps come in many different shapes and sizes, from bug zappers to fly paper. If you want to rid your garden of fungus gnats congregating, then read our reviews of the best fungus gnat traps in 2022.

Fungus gnats are one of the most annoying flying insects in your garden. If you’ve ever been gardening and had some of them caught in your mouth or nose, you know exactly what we’re talking about.

They also cause trouble for your house plants and plant soil. Their larva can damage roots and prevent your house plants from growing. Unfortunately, they’re tinier than flies and mosquitos, making them even harder to rid of them than other garden pests.

What are Fungus Gnats?

Fungus gnats are black, winged insects that are often mistaken for fruit flies. They measure just 2-3 mm in length and have long legs in proportion to their small bodies. Fungus gnats are attracted to moisture and are commonly found near houseplants.

They love the warm environment as well as any food and bacteria buildup in the houseplants.

Although they do not bite or sting, fungus gnats can cause extensive damage to plants, particularly when they infest young seedlings. The adults lay their eggs in the soil, and the larvae feed on roots.

This can interfere with a plant’s ability to take up water and nutrients, leading to wilting and yellowing leaves. Fungus gnats are more of a nuisance than a health hazard, but infestations can be difficult to control.

Are Fungus Gnats the Same as Fruit Flies?

Fruit flies and fungus gnats are both small, flying insects that can be a nuisance in the home. However, there are some key differences between these two pests. Fruit flies are attracted to fruit, while fungus gnats are typically found near potted plants with moist soil.

In addition, fruit flies feed on fruit, while fungus gnats primarily feed on plant roots. As a result, fruit flies are more likely to cause damage to fruit crops, while fungus gnats can damage plant roots and lead to stunted growth of your houseplants.

While both insects can be a nuisance, understanding the key differences between these two pests can help you better manage them.

Why it’s Better to Use Fungus Gnat Traps than Poison Them

There are no commercial poisons for fungus gnats. Instead, most farmers will trap them with a sticky trap or a chemical solution. In some extreme cases, you can dampen the soil with hydrogen peroxide to kill off their larvae as well.

However, Fungus Gnats in small numbers are relatively harmless to your plants and garden. They do not eat potted plants, and they don’t bite people. Using a strong chemical or poison will only be putting your house plants and plant soil at unnecessary risk. Instead, try a trap or a natural remedy.

How to Prevent Fungus Gnats

Gnat infestations can be such a nuisance. Fortunately, most gnats (as well as white fly, drain flies, and other bugs) can be killed or rid of by a simple insect trap.

Before we get into the best traps to solve your fungus gnat problem, let’s look at some of the best methods to prevent fungus gnats from ever showing up.

Dry Out the Soil

Fungus gnats are attracted to damp and humid conditions. It’s essential to give your plants enough water every day, but keeping your houseplants’ soil too damp will attract annoying fungus gnats and other flying insects into your house.

If you notice that fungus gnats appear more frequently, slow down on watering your plants for a couple of days. Once the top two inches of the plants’ soil are dry, you can begin watering again. This will allow the soil to dry out properly and won’t damage your plant’s water cycle.

Mosquito Dunk

Mosquitoes, fruit flies like to lay larvae in shallow pools of still water. A mosquito dunk is a trap consisting of still water and a special bacteria to eat any larva that a flying insect lays inside.

To make a mosquito dunk, fill a large jug or can with water and add the special bacteria pellets. Make sure to break the pellets into smaller pieces before adding them to the water, and let them soak overnight.

Since fungus gnats lay their larvae in the soil instead of water, you can use the mosquito dunk water to water plants infested with fungus gnats. If you repeat this process for a few months, the gnats should eventually leave before spreading to the rest of the garden.

Watch Your Drainage Holes

Drainage holes are the tiny holes on the bottom of a flower pot. They allow water to seep out from the bottom so the soil doesn’t get too moist. Typically, fungus gnats lay their eggs at the top of the pot. However, some fungus gnats like to lay eggs in these holes as well.

Cover the hole with a piece of synthetic fabric so the flies can’t eat through it.

This homemade solution is another popular gnat trap on the market. You can make it by combining warm water (half cup), apple cider vinegar (two tablespoons), sugar (one tablespoon), and a few drops of liquid dish soap (6 drops).

Add water and all the other ingredients into a bottle. The liquid dish soap helps break the mixture’s surface, so it can catch the bugs even more effectively.

Apple cider vinegar is more effective than just plain vinegar when it comes to attracting fungus gnats and other fly species.

Place this concoction near your infested plants, and the adult gnats should fly right in and die. This is a great way to protect your plant against this type of fly.

Red Wine Fly Trap

To make a red wine fly trap, all you need is a shallow dish and some red wine. Simply pour the red wine into the dish and wait for the flies to come. The flies will be lured to the red wine, and they’ll fall into the trap, stick in it, and eventually drown.

Once they’re dead, you can simply dispose of them. This trick is both effective and environmentally friendly! Just simply place your trap near the affected plant.

Katchy is a new type of bug catcher sponsored by Amazon. It specializes in catching and killing mosquitos, gnats, moths, and fruit flies. This device is interesting because, unlike other bug catchers, it does not shock the insects.

Instead, Katchy attracts insects with UV light and then uses a fan to suck them inside of the machine, where they get stuck to a glue board. This works for both outdoor and indoor use.

Like most airborne insects, fungus gnats are attracted to light, so if you place this device near your houseplants at night time, it has a good chance of catching several of the gnats inside.
