Full Description

Also known as compost fly / fungus gnat, Sciarid fly is a common pest of greenhouse plants and houseplants. Female fungus gnats lay 50 – 300 eggs each in moist soil and it takes 28 days from egg to larva and pupa to adult, so numbers tend to build up slowly, but can then quickly get out of control. The Sciarid flies crawl over the compost surface and if disturbed fly on to the lower leaves – there can be very annoying especially on houseplants. The larval stage in the compost attacks the roots and can kill young seedlings. Control sciarid fly naturally by applying Sciarid Nematodes.

Sciarid Fly Nematodes are safe to use on food crops, safe for children, pets and wildlife and are easy to use – mix the nematodes with water and water directly into the affected pots / trays. Sciarid Fly Nematodes need a daytime soil temperature of 10°C. Safe for plants – will not scorch tender seedlings or young plants. Safe for you – use on plants in your living room or conservatory. Sciarid Nematodes are a living, perishable product (it will keep for up to 2 weeks in the fridge), so please order when the pest is present and you are ready to treat. Available in two sizes – choose between a STANDARD 15 sqm pack or a LARGE 50 sqm pack.

    Ordered nematode worms for fungus flies for my balcony ‘grow-arium’, arrived promptly and has diminished the fly populous and will hopefully eradicate them completely. My chilli plants are on the road to recovery. A very good green solution, would recommend.

    Excellent product.. worked really well.. all scarred fly gone in 3 days

    Selling non-chemical pest control which sorted our fungus gnat infestation great!

    I found Green Gardener online after finally working out what I needed to get rid of a fly infestation in my houseplants. Their website was clear, it was easy to work out what I needed, and as a non expert I found the ‘purchased with’ section useful as it lead me to some things I wouldn’t have known about but which were very useful. The website was easy to use, the delivery was quick and the prices were reasonable, and I liked the fact it was a smaller family owned business (why give more to the conglomerates than you have to!) All in all a successful shopping trip and I’ll be back for some bee houses soon!

    I came across Green Gardeners site when looking for Nematodes for a Fungus Gnat problem on a few houseplants. I ordered the Sciarid/Fungus Gnats Nematodes for 15sqm, the dispatch and delivery was very quick. The order came with good, clear instructions on how to store and use the nematodes and what the “shelf life” of the nematodes were, some things I had no clue about before I ordered, so it was incredibly helpful. I kept the little plastic container of nematodes in the fridge for a couple of days before use, i then made the solution and diluted it and used as instructed. I only had a few plants that I constantly noticed fungus gnats on, but I watered all of my plants with the treatment to be safe, I have 30+ houseplants and I had plenty of treatment left, that I then used in the garden. It’s been a couple of weeks since I used the treatment and haven’t noticed any more fungus gnats, I’ve tapped on all of my houseplants, which would usually cause any fungus gnats to fly away, but I haven’t noticed any at all which is so great! I’ve tried other fungus gnat control solutions before and the best thing that worked then was the yellow sticky traps, but they didn’t stop it as they only caught the adults and not the larvae. I’d highly recommend this for anyone with a fungus gnat problem!

    The nematodes arrived promptly and the user instructions were clear, the gnats have gone.

    Had tried so many things to get rid of fungus gnats that had taken over both of my amaryllis – sticky traps, changing the compost, not watering. None of it really worked – the sticky traps did but they didn’t stop the infestation for good just controlled it somewhat. I had almost given up hope when I came across these. I was SHOCKED to observe that they completely solved my fungus gnat problem in less than a week! Life-changing and wondrous! Couldn’t recommend enough.

      The nematodes are amazing and unlike chemicals the pests cannot develop a tolerance. Kind regards Jon @ Green Gardener

  8. Robin Harding

    Excellent products and fast delivery. Great solution to the gnat infestation!

  9. William Smith

    Very quick delivery, they arrived the next day somehow. Quality of the product was good (Sciarid Nematodes), they got the job done very quickly! Will definitely be using green gardener again.

    Bought Sciarid Nematodes & Sciarid Zoot Off – both arrived promptly and so far worked fantastic. Will definitely be reviewing website for other items – great stuff.

    Can’t praise Jon highly enough! I had a serious sciarid fly infestation and was time-restricted in when I could deal with it. Pre-purchase, Jon gave me first-class advice on the best treatments, and times to apply them. I followed them carefully and can say that since then the difference is beyond all expectations! I can count on my fingers the number of flies I’ve seen since treatment and truly believe I’ve finally gotten on top of them: the relief is immense and I’m forever grateful !! Thank You!!

  12. Helen

    These nematodes are incredibly effective at getting rid of those pesky little black sciarid flies that manage to get into my plants in every room of the flat and then fly past my nose when I’m watching television. The nematodes are so dramatically effective that I feel sorry for them because they quite quickly exhaust their source of nourishment!

  13. Dev Patel

    Great service and just what we needed to get rid of the Fungus Gnats.

  14. Shadi Bavar (verified owner)

    Order arrived quickly, and the nematodes eliminated my fungus gnat infestation like nothing else I tried.

  15. Tom

    Great service. I have ordered three times lol. I made the mistake by not adding the yellow stickers to catch the flies, because although the nematodes have killed the larva – the adults were flying around and after a few days they reproduced again. This time I am on a mission. Thank you for such a great product!

  16. Chris Hale (verified owner)

    Sciarid Fly Nematodes Order fulfilment is quick and I can recommend the product.

  17. Anonymous (verified owner)

    Very quick delivery, (within a couple of days), with no additional postal charges. We are now fungus gnat free after using the triple attack method of nematodes, Zoot off top dressing and sticky fly catcher strips.

  18. Chelsea Sinclair (verified owner)

    Excellent. Prompt delivery, plenty of information given about the product and how to use it, no more fungus gnats since I used it!

  19. Cathy Smith (verified owner)

    I purchased the nematodes to deal with the black fungus gnat, and so far so good. The number of flies has reduced dramatically. The order was promptly dispatched with clear instructions on how to use it. I will use the company again.

  20. Victoria Collins (verified owner)

    I ordered Zoot off and nematodes for an infestation of sciarid flies. The website is full of useful information and delivery was quick. Great customer service and problem solved!

  21. Anne Cockitt (verified owner)

    My order of nematodes arrived swiftly and they were effective, no sciarid flies around my indoor plants after about 10 days of the treatment. Thanks.

  22. Rhona (verified owner)

    Excellent products, particularly the Sciarid Fly nematodes which work! Prompt delivery and service.

  23. Anonymous (verified owner)

    Every year when I bring in my houseplants we get an infestation of sciarid flies, and every year I order nematodes from Green Gardener, and every year they arrive promptly and work perfectly to get rid of the flies. Thank you Green Gardener!

  24. Janet Bott (verified owner)

    Gave good info on the product, which did the job with no nasty chemicals. Delivery was prompt.

  25. Karen Oliver (verified owner)

    Purchased nematodes for house plant fly issue. They have worked where nothing else did. Took a little time but did the job. Purchased arrived promptly and will buy again from here if needed.

  26. Anonymous (verified owner)

    Very fast delivery, great price and great quality product. I ordered nematodes to deal with fungus gnats in my houseplants. They worked really fast! I can only assume they must have been all alive and ready for battle. Thanks green gardener!

  27. Anonymous (verified owner)

    Ordered nematodes, that came fast, instructions were good and it has solved the issue with sciarid fly.

  28. Christine Elliott (verified owner)

    It’s the first time I have bought from Green Gardener and I am sure it won’t be the last. My plants had an awful sciarid fly infestation but thankfully, the nematodes (which were not at all scary, as I’d feared) got to work and sorted it out. I am keeping fingers crossed that the collars I bought will deter hosta-hungry snails! The company has a great ethos, products are excellent quality and value.

  29. Carol Swarbrick (verified owner)

    I had been over run with the little black flies , and couldn’t seem to find a product to treat my plants . I found the nematode product on green gardener and I it works, brilliant Stuff . I would definitely recommend . Green gardener were very quick with the postage would certainly use them again.

  30. Timothy Harwood (verified owner)

    Green gardener has a great selection of environmentally friendly ways of controlling pests (slug nematodes and the sciarid fly nematodes are my usual and they work) Delivery is always quick and well done. I love the slug nematode programme that means I can buy the subscription and they are sent out at a regular interval which means I can keep on top of the pests.

  31. Anonymous (verified owner)

    I have bought the Sciarid Nematodes and Zoot off before and they work every time. Delivery was fast as usual.

  32. Sharon Ackroyd (verified owner)

    Very good site for all things pest related. I’ve bought copper rings to deter slugs which have lasted well and do the job particularly well whist the plant is young and vulnerable. I’ve also tried nematodes, which work well for both slugs and Sciarid flies. I’ve had no problems ordering or with deliveries, very happy with the service.

  33. Anonymous (verified owner)

    Bravo. Very pleased with Green Gardener. Ordering is easy and efficient. Delivery is prompt and safe and all products were as described, so no disappointments. Pricing is very competitive too.

  34. Alice Burns (verified owner)

    As someone who is new to gardening ‘Green Gardener’ products and information are not only needed but very much appreciated. Orders come quickly and on time. To date the Sciarid Fly Nemadodes seem to have done the trick. I am very happy with the products and service provided. Thank you. Alice.

  35. Elizabeth Murphy (verified owner)

    Really excellent supplier. I have now purchased from Green Gardener a few times. (Cat Watch and sciarid nematodes). The website is clear and has lots of information, delivery was fast and everything was packed really well. I would definitely recommend Green Gardener, and they have a great selection at very competitive prices. I will certainly be returning when I need more supplies. Thank you for providing a great service.

  36. Emer Hegarty (verified owner)

    I’ve bought Sciarid Fly Nematodes twice now also and Amblyseius Cucumeris Sachets for Thrips once from Green gardener for two separate pest problems over the span of two years, each time, I’ve had such great success with treating the pest problem using the Scairid fly nematodes so I’ve been incredibly happy that Green gardener provides a source for very affordable natural pest control… While also, the dispatch is always prompt with quick delivery and great email notifications of when orders have been received/dispatched.

  37. Tracy Appleton (verified owner)

    Products arrived quickly (nematodes and Zoot Off) and carefully packaged. Instructions for using the nematodes were clear. I wish I had discovered this company much earlier in my plant owning life but am very happy that I am now aware of them. I have since returned and bought several different products and all arrive in a timely manner.

  38. Sarah Scriven (verified owner)

    Fabulous products. I had a terrible fungus gnat infestation with my house plants and my garden. I cracked on with application following the instructions provided and I noticed a difference on the 3rd day and by day 7 I noticed a huge improvement and everything has thrived ever since. Delivery was speedy, I’ll use these guys again superb.

  39. Sophie Vincent (verified owner)

    I had a fungus gnat infestation. I used the nematodes alongside yellow sticky traps and it’s worked! Three weeks on, I’ve hardly seen a gnat. Easy to use, quick delivery. I’m really pleased, as I’d tried just sticky traps before and changing soil etc and they had still come back. This time they have all gone. Also my son had a look at the nemotodes with his toy microscope, which was fun for him.
