About this deal

Fungus gnats are actually attracted to soil, rather than plants, so they can infect all plant types. Start your slug control early and apply at least a week before planting to ensure your garden is safe from slugs. Aphaereta debilitata is a naturally occurring parasitoid of shore fly larvae, particularly where IPM is being used with minimal use of plant protection products. In HDC/AHDB project PC 239, A. debilitata was found in large numbers on several UK herb nurseries using IPM and parasitised up to 99% of shore fly pupae on a crop of mint.

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).Alternatively, consider purchasing our new 'A Gardener's Guide To Biological Control' book, written by Dragonfli founder, and expert, Julian Ives. The book is available here. 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. The only danger with this is the strong smell may invite other unwanted pests into your home. Neem oil This ground-dwelling predatory rove beetle is available for control of both sciarid and shore flies. Both the adults and larvae will eat sciarid and shore fly eggs, larvae and pupae in the growing media. They will also eat other prey in the growing media, including thrips larvae and pupae. The removal of peat composts to more organic based composts has been a positive move for the environment, but the new organic based composts do also attract more Fungus Fly, which enjoy feeding on organic matter. This has led to a general increase in the activity of this particular pests for many people growing house plants.

Large larvae can be seen with the eye crawling along the surface of soil the plant is growing in, or around the surface between root ball and plant pot. Symptoms of sciarid fly larvae feeding on seedling stems are bites taken out of the stem just above the soil surface, at this young delicate stage it does not take much to result in the death of the plant, which may appear as patches of dead seedlings within a seedling tray. Symptoms of feeding on the roots are poor plant condition, where its roots are unable to provide it with enough water and nutrition to appear healthy. Sciarid fly (also known as compost fly) or Fungus Gnats are a common pest of greenhouse plants in the spring. The nematodes need to be applied carefully, following all supplier recommendations . T he suspension of nematodes should be kept agitated during application, and the growing media kept moist so that the nematodes can survive and move around . The nematodes are effective in growing media between 10°C and 30°C, depending on product . On highly susceptible crops and in propagation, the nematodes are recommended to be applied preventively.Fungus gnats, also known as sciarid flies, affect all types of plants including flowers, fruits and vegetables. They especially love indoor or greenhouse plants in pots and containers due to their moist soil and/or humid conditions, and can be very irritating to have flying around inside. The whole lifecycle is about 28 days, but the adult fungus gnats live only around 7 days. Where do fungus gnats come from? Using neem oil to kill gnats is a popular ‘natural’ method in the US, where it is approved. However, neem oil isn’t currently approved for use in the UK.

You can create your own gnat trap simply with a bowl of apple cider vinegar and a few drops of washing-up liquid. The vinegar attracts the gnats, whilst the washing-up liquid makes it hard for them to leave. Hypoaspis mites are a great solution, they are hard working, crawling over the compost to find their prey. They are fine in dryer conditions don't need lots of compost to live in. They can work well as a preventative measure to stop new outbreaks as they have a reputation of living for quite a long time without food (when they have been previously fed). Maybe even giving you protection for a few months. Save your houseplants and seedlings from Sciarid fly/ Fungus gnats and larvae damage with our parasitic nematodes. Again to prevent egg laying, try removing the top inch or so of soil and replacing it with gravel or sand.Many people are concerned with bringing something ‘live’ into their home, but there’s nothing to worry about. They can’t interact with humans (or pets) at all. They can only interact with tiny larvae like the sciarid fly. You cannot see them with the human eye and they cannot leave the soil.

Certain predatory mites can also be applied to the surface of the house plant compost, and can provide a very useful additional control of Fungus Fly. These tiny predatory mites feed on the small Fungus fly larvae they locate on top of, and just under, the compost surface. The most effective predatory mite to apply against Fungus Fly is called the Macrocheles robustulus, also known as Mighty Mite.
