Product Information

You just apply to moist soil when the soil temperature is above 5ºC and ensure the soil does not dry out for at least two weeks after applying. St ratiolaelaps scimitus ( Hypoaspis miles) and Macrocheles robustulus are ground-dwelling predatory mites commonly used for sciarid fly control and can be very effective. Adult females of both species are up to 0.8 mm long, off-white , with a pale brown shield covering most of the upper surface of the body.

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. The whole lifecycle is about 28 days, but the adult fungus gnats live only around 7 days. Where do fungus gnats come from?

How to identify fungus gnats

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. Adding some dish soap to a spray bottle and spraying the top of the soil can help kill off the gnats. Homemade fungus gnat traps Again to prevent egg laying, try removing the top inch or so of soil and replacing it with gravel or sand.

Start your slug control early and apply at least a week before planting to ensure your garden is safe from slugs. The nematodes come complete with instructions, they are just mixed with water and then applied using a watering can or nematode applicator. The nematodes are easy to apply and completely safe to use around children, pets and wildlife, making them the perfect solution for organic gardening. Steinernema feltiae is the species recommended for sciarid fly control and is commonly used on protected ornamentals where it can be very effective. Steinernema carpocapsae (recommended for shore fly control – see below) will also kill sciarid fly larvae, however S. feltiae is more effective . The nematode suspension is applied in water as a growing media drench. The nematodes move through the growing media to find a sciarid fly larva and enter the body, where they multiply and release symbiotic bacteria that kill it. The dead sciarid fly larva rapidly decomposes, releasing the nematode juveniles that have multiplied inside the body, and these can then move to find and infect other larvae . Nematodes can also be safely applied in combination with soil borne predatory mites.

However, they can also feed on live roots, damaging your plant. This can cause deformed growth or death. Water your plants less. Many a houseplant is watered more than it actually needs. Try watering it less and see how it responds. 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. Adult flies are a nuisance, often flying around pot-grown plants in a home, greenhouse or cold frame.

Fungus gnat larvae are normally brought in from infested potting soil, or soil in a new houseplant. They can also be brought in by firewood, since they like the damp bark. Fully-grown plants are much less likely to be damaged, but can be if there's no other food source for the Scaridae. Where do gnats live? Sciarid fly (also known as compost fly) or Fungus Gnats are a common pest of greenhouse plants in the spring.

Long yellow roller traps will catch more adult sciarid and shore flies than standard-sized traps but should be used with care in IPM programmes as they will not control the pests in their own right and will also catch flying beneficial insects . The only danger with this is the strong smell may invite other unwanted pests into your home. Neem oil 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. Mix the concentrate solution and extra water for one minute to distribute the nematodes evenly in the solution. Apply immediately after mixed. 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.

The adult beetle is 3 – 4 mm long, dark brown and shiny, with beaded antennae, short wings and an upturned rear end. The adults are very active and can run and fly but often remain hidden within the growing media and under pots or trays. The young larvae are small and white , while the older larvae reach 3 – 4 mm in length and are brownish-yellow . D . coriaria is recommended for use in t he early stages of infestation.

Chemical control of sciarid and shore flies

Natural enemies of Fungus Fly can be used to control the larval stage of its life cycle. By killing the larvae of the fly, the life cycle of the pest is broken and as such no more adult flies will appear. The best way to accomplish this is with the use of the nematodes contained within our Fungus Fly Killer. The adult sciarid flies live on and around the compost surface of pots, more commonly indoors rather than outside. The flies themselves are an unsightly nuisance but most of the damage is caused actually by their young. The small white larvae live in the compost and feed on the tender roots of plants and cuttings. They will also come to the surface to feed. Adult fungus gnats only live on liquids, and don’t actually do any damage to plants. Their presence is just very irritating. Nematodes are capable of surviving the odd frost; so don't worry if the temperature falls after you have applied the nematodes. Repeat applications may be required after 4 weeks to prevent the build up of fresh Fungus Fly larvae.
