60 sqm Sciarid Fly (Fungus Gnat) Nematodes

£9.00

Usually dispatched in 1-3 working days

Save your houseplants and seedlings from Sciarid fly/Fungus gnats and larvae damage with our parasitic nematodes. 

Biological controls are not always kept in stock, they are ordered in fresh.  This can sometimes lead to a time lag between when you place the order and when it is despatched.

The adult fungus gnats/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. 

Nematodes are more effective if the sciarid population is high. The nematodes are watered on, and attack the sciarid larvae underground. Parasitic nematodes seek out suitable hosts by swimming in the thin film of water on soil particles, locating hosts by detecting carbon dioxide and other waste products. Once they find a host, they enter the body cavity through the breathing or feeding systems, and release bacteria (Xenorhabdus). The bacteria kills the host within hours, and the nematodes grow and reproduce within the 'broth', which they produce. The next generation of infective juveniles leaves the dead host, and moves in search of fresh hosts.

You can read the instructions for the nematodes HERE.

Combine with yellow sticky traps for better control.  A second treatment may be required depending on the level of infestation and the life cycle stage of the pest.

The pack size is 60 square metres. This is the maximum it will treat but you can use it for smaller areas or small collections by using less water to mix it up.

Apply only when the pest is present and the growing material is above 10°C

Follow the instructions on the pack carefully, You will need a measuring jug, a large bowl or bucket and a watering can or spray bottle
Important information
Don't forget that these are live creatures, and cannot be stored - you can keep them in the fridge for a week or so, up until the use by date on the packet, but after that the nematodes will slowly die off.

Q - I have been keeping the compost quite dry to try and get rid of the gnats, will this be ok for the nematodes?

A- No, the compost will need to be kept moist as the nematodes are swimming creatures and will perish if they dry out. If you were to squeeze the pot 1 or 2 drops of water would come out, so not waterlogged but not dry.

Q - I only have 1 or 2 houseplants, how do I use it?

A - Once you have mixed up the solution you can apply with a watering can or spray. If you are treating just a few plants then you can make the solution more concentrate. Just mix with the amount of water you would normally use to water your plants. Use it on any other plants inside and any spare growing material you may have stored.

Fungus Gnats

"Thank you Ladybird Plant care. I have learned so much from you guys over the years. I now understand the breeding cycle of these little critters. I will also use this brilliant product all year round as a preventative. You have preserved my lovely blooms time and time again. An excellent product that’s delivered almost instantly if you apply Mondays. Again many thanks and happy growing 👌"

Fungus gnats? What fungus gnats.

"I have almost 100 plants. So of course I had fungus gnats. I’d tried those stupid sticky things but they just got stuck to the cat’s fur. I got two lots and one did all my plants for the first treatment and the second done a couple of weeks later just to be sure. Tbh I think it got them all the first time. Brilliant product. Only issue was my daughter was a bit sad we suddenly didn’t have actual toads sent to us to do it. Really pleased with them."

Great stuff delivered fast

"Like everyone I have had scuffling odd fly or two which I had gone to war with iso sb and other stuff. Have used the nematodes and that’s been the end of thrips after a couple of weeks I have seen non. I have started with the subscription as I believe prevention is better than cure. Happy to keep my subscription going which tells you how well this works - great stuff delivered fast"

Disappointed

"Previous applications worked well but despite applying once and again 2 weeks later I am still squashing them on my windows. I've added sticky traps to every house plant ,which are catching flies but still they keep coming!"

Fungus gnats were completely gone!

"It’s crazy how quickly these can multiply! But after using beneficial nematodes, I forgot I even had them! I couldn’t believe how well these worked! Yesterday I saw one fungus gnat flying around so not going to wait, I need to act fast and I’m back buying another pack :)"

Dorota (5/5)

VERY HIGHLY RECOMMEND - WORKS 100% !!!!

"As first time user, I am incredibly pleased to say that I after I applied my nematodes it took only a couple of days to have an effect - no more gnats!!!! At last something that actually works long term. I have tried other forms of natural-control (bacterial and plant based liquids) for treating fungus gnats but without success, so these nematodes are a revelation!"

Sarah S. (5/5)

This worked!

"It was easy to use. . . . just follow the instructions. I watered all my houseplants once then a few days later mixed up another lot and watered them again. My house plants are now completely clear of those pesky little bugs! Can recommend 👌"

Alice P. (5/5)

No more gnats !

"Brilliant product . Used 1 sachet for 2 large monstera and a few smaller potted plants . 6 days later and not one gnat left ! I didn't realise it was so effective! Highly recommend."

Bugs and beasties in the hot house.

"The encarsia seems to be working but the nematodes are not quite so efficient. I will be ordering more when I’m back from my half term break."

Fungus knat treatment

"We had a serious infestation of fungus knat on our indoor plants in the conservatory which had spead around the house. We had tried various gravel solutions and several numerous sticky traps in each plant pot, in all the pots (which always got filled up very quickly). I'd heard of nematode treatment before but never really liked the idea of them, but in desperation ordered the treatment from the Ladybird Plant Care company, the package came very quickly and a personal email from the company with additional advice. The treatment was easy to use and to my surprise, the next day there was absolutely no sign of the flies anywhere - we were very surprised as we expected it to take a few days to have any effect! A few flies started to reappear about 10 days later, and fearing a repeat of the infestation we ordered another pack! All is now well. We have had the odd one or two and still use the yellow sticky traps just in case, but the flies are few and far between. It's such a relief. And now we know that if they ever come back, we will reuse this product. Overall we are extremely pleased with this product and the service."
