How Do I Get Rid of Fungus Gnats?
You need to stop the cycle! First, if it’s a type of houseplant that can tolerate it,让锅变干completelyin between waterings, which causes the eggs and larvae to become desiccated and die, says Skvarla. If the infestation is small and you occasionally let your pots dry out, you’ll get at least partial control.
圣icky traps,which you poke into the soil, are helpful for monitoring fungus gnat levels and can indicate what pots in which you may have fungus gnats. But you won’t be able to kill enough adults to wipe out every fungus gnat because the traps don’t contain an attractant— they just catch any fungus gnat which happens to flutter by, says Skvarla.
Sundews and other carnivorous plantsset near other houseplants also can help catch the adults. In fact, these types of plants often are used for management of pests in greenhouse settings. However, while both sticky traps and carnivorous plants can be part of the solution, they usually won’t solve the problem entirely.
Unfortunately, there are no sprays or insecticides that are effective. Youcanuse a biological control, a type of bacteria calledBacillus thuringiensis subspecies israelensis,or Btifor short.Bti is a larvicide that is specific to certain pestsand it works well, though it may need reapplied periodically, says Skvarla. It’s often found in a granular form that is activated when watered into the soil surface.
If they don’t really bother you, you can just leave them alone. After all, they’re not going to hurt you, your pets, or your plants.
