"gantnix' stops fungus gnats without using chemicals. Photo by Doug Oster
There's nothing more annoying than fungus gnats buzzing around houseplants and this time of the year I get lots of questions about what to do about the pests. Once they get going, it's hard to stop them. I often tell gardeners to let their plants dry out and that can really slow them down.
Fungus gnats love wet soil, so for most houseplants, restricting water will help. There are some plants, like cylcamen though, which need moist soil to keep blooming through the winter.
While visiting Soergel's Home and Garden in Franklin Park to film a Digging with Doug segment on seed starting, they had some "gnatnix," a non-toxic control for the gnats and it only costs seven dollars. When my boss looked over the video, she was overjoyed to see the product as her plants are plagued with gnats.
It's made from recycled glass and forms a barrier on top of the soil when applied. It prevents adult from emerging, the larvae from hatching and deters the females from laying eggs. By disrupting the fungus gnats life cycle, the pests can't survive.
I'm thrilled to have this product to recommend to gardeners so they don't have to use chemicals indoors to battle the gnats.
