About this deal

Adults are able to find their way from outside into growing areas through gaps in protection, and can continually re-infest in this way. Even chemicals that have shown an effect have only had a transient effect if placed in contact with for a short period of time.

Remove the sponge from the kit and you will notice a light brown patch on it , those are the nematodes.This site is maintained by Center for Agriculture, Food and the Environment in the College of Natural Sciences. Preventative – As a preventative apply as part of a structured periodic application or in advance of historical seasonal infestations. The eggs hatch within three to six days, depending on the temperature, and will then go through four larval instars.

Irrigate well immediately after treatment, and maintain moist soil conditions for the next 7 to 10 days. Repeat applications may be required after 4 weeks to prevent the build up of fresh Fungus Fly larvae. The disadvantage here is that young plants have vulnerable root systems, and they may have already been destroyed by the time the gnats have been eradicated.Tip: Fungus gnats are usually brought in from the grower when acquiring new plants, or sometimes they come in bags of potting soil.
