Sciarid Fly Killer Nematodes 15 sqm

Product Information

They can be found hovering around your plant, or crawling over them. Indoors, you will notice a gnat slowly flying around the room. They’re attracted to light, as well as heat and scent. For this reason they may seem attracted to you as well. Bob Vila and its parent company, Recurrent Ventures, puts conservation and sustainability at the forefront of nearly everything we do. Though effective, some of the solutions offered in this content are not organic or sustainable. Bob Vila’s staff encourages readers to make informed choices about maintaining their home and property, and opt for solutions that will not have detrimental effects on the health and longevity of this planet and its inhabitants. Adult fungus gnats live for about 7 days. In this time each female lays a staggering 150 eggs in the soil of your plant. After about 5 days, these eggs hatch into larvae. These larvae are the ones that can cause root damage and live up to 14 days. They then form pupae to transform into the adult fly form, which takes about 5 days. How long do gnats live?

Control using nematodes as a drench and then try to keep the surface of the compost as dry as possible (stand trays/ pots in water and soak from the bottom up rather than watering from the top). Repeated applications are often needed. Reapply in 2 to 4 weeks under moderate to heavy infestations. For longer term crops, apply at the beginning and at mid-crop. Fungus gnats are attracted to moist soil and planting media, which is why overwatering houseplants is perhaps the most common cause of fungus gnat infestations. Q. Should I dispose of infested soil in my potted plants to get rid of fungus gnats?Mix this powder in a 1.5L watering can and water the soil around your plant. Keep the soil moist for two weeks.

Prevention is always better than cure. As well as trying Yates Gnat Barrier, there are a couple of other things that you can do to prevent incursions from Fungus Gnats (see How to Prevent Fungus Gnats Appearing). Fungus gnats are often more numerous in composts that are constantly wet, allowing compost to dry can reduce infestations, provided this does not affect the health of plants. Potting media formulated for houseplants is the best choice for indoor plantsMake sure the compost is moist before application, as the nematodes need to be able to move through the compost. Fungus gnats (or sciarid flies) are the little flying bugs around your plant. They look like small, pale flies with translucent wings that are slow fliers and don’t make an audible buzzing sound. Eradication more likely as works over a 2 week period where nematodes multiply until all the larvae are dead Calculating the number of nematodes you need depends on the treatment area. Generally speaking, we recommend 500,000 nematodes per square metre, which might sound like a massive population, but remember: they’re teeny tiny.
