Outdoors, they are most common during winter and spring in interior areas of California, when water is more available and cooler temperatures prevail. They can occur during any time of the year in moist coastal regions and indoors. MANAGEMENT

When larvae or insects eat a plant or material containing imidacloprid, their nervous system is disrupted and they eventually die.

A female can mate shortly after emerging from her pupal case, and the cycle begins again. Fungus Gnat Control Methods Apple Cider Vinegar Pesticide control The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner.Because adult fungus gnats are attracted to light, you first might notice these pests flying near windows indoors. However, in comparison with more active species such as the common housefly ( Musca domestica), fungus gnats are relatively weak fliers and usually don’t move around much indoors. Fungus gnats often remain near potted plants and run across (or rest on) growing media, foliage, compost, and wet mulch piles.

Fungus Gnats – What Works And What Doesn’t How To Get Rid Of Fungus Gnats – What Works And What Doesn’t

Place the hydrogen peroxide and water into the spray bottle. Replace the lid and gently shake the bottle to combine the ingredients. Allow the top of the potting soil to dry before you begin the treatment. Spray the solution under your plants, over the top of the soil. Plan on using the solution within 24 hours for maximum effectiveness. How Long Is BTI effective In The Soil? If fungus gnats start to emerge after you’ve brought your houseplants inside, you will need to use one method to kill the larvae and one method to catch flying adult fungus gnats. For fungus gnats, the manufacturer recommends using 4 tablespoon, or 1/4 cup, of Mosquito Bits per one gallon of water. Sunlight also breaks it down faster after it is activated. Once you’ve made a batch of the solution, keep it out of sunlight. A study reported that sunlight can reduce the effectiveness up to 60% within 24 hours. Mosquito DonutsFungus gnats ( Orfelia and Bradysia species) are dainty, dark flies much akin to mosquitoes. Adults have segmented antennae longer than their heads, which distinguishes them from shore flies, also often found in greenhouse environments. Because the BTI is activated by alkaline environments, it breaks down faster when used in acidic soils. But typically, you should expect it to remain effective for several days to two weeks. One study reported that it remained effective underneath the soil’s surface for four to twelve months. If fungus gnats emerge 2 weeks after treatment, you’ll need to reapply the solution.

This product contains a blend of different species of nematode, this is perfect for controlling these fly larvae. The strength of hydrogen peroxide is also important. People recommend using a 1:3 percent ratio of peroxide to water. Using this ratio, a 3% strength which is already 97% water would be severely diluted and less effective, and a 35% strength would likely be too strong and could damage the plant’s roots.

Repeat this pyrethrin fungus gnat treatment until all signs of infestation, including flying adults and larvae and eggs in the soil, disappear. This may take some time, especially if several houseplants are in quarantine for these pests. To get rid of fungus gnats faster, consider using this method in addition to the above alternatives. STEP 4: Replace the top layer of soil. Add water to a one gallon jug and pour in 1/4 cup (or 4 tablespoons) of Mosquito Bits. Shake the jug well and let the granules soak for around 6 hours.

Plant Isolation Or Encapsulation

You can top dress your houseplants with Steinernema feltiae, or beneficial nematodes to destroy the fungus gnats during their larvae stage. The microscopic roundworms penetrate the fungus gnat larvae, then release a bacterium that works to consume the insect from the inside out. They are safe to use around plants, pets, and your family. When bringing any new houseplant home, keep it in a different room from your other plants for at least a few weeks while ascertaining if it conceals unwelcome visitors. Once you’ve spotted insects on a plant, remove that container a safe distance away from your other plants. We used a permethrin spray on the adults after agitating them into flight by shaking plant pots. They seemed pretty annoyed at getting sprayed, but we didn’t notice any dead gnats a few hours after spraying so we can’t say it worked. Hydrogen Peroxide Fungus gnats may be confused with fruit flies. The difference between the two is evident upon close inspection. Fruit flies have bodies that are perfect miniatures of the house fly, while fungus gnats have long legs dangling from an elongated body, much like a mosquito. Place the bagged soil on a slightly elevated surface, such as a pallet in a sunny location, for about 4 to 6 weeks.
