Nemasys Natural Fruit and Veg Protection Nematodes

So I suffer with the dreaded black fly in my house plants and although I manage levels using sticky traps, sometimes a little more is needed to really kill them off. I bottom water my plants, I have a layer of grit on my plants and do everything else that I should but I find this really is the best way to heavily reduce numbers. It doesn’t look like much when it turns up, some sticky powder in a plastic dish that is hard to believe is alive in anyway but you keep it the fridge as soon as it arrives until you use it. The recommendation is to use it quite soon after purchase so make sure that you don’t buy it just to stick in the cupboard until you need it. Only purchase it if you are planning on treating Immediately. This particular one actually treated a lot of different bugs, but I wanted something that treated blackfly (sciarid flies). To start with you have to dissolve in a large quantity of water so I just used an old bucket and a Pyrex jug to measure out the required amount of water. I then took the lid off and put the packaging inside the water and swirled around until it dissipated. Then you would add half a litre of the nematode mix to a watering can full of water and then treat your plants. It sounds more complicated than it is and once you’ve made your mix, you just need 1 jug of mix to I think it was 9 jugs of water. Once I worked out where I needed to fill it to, I drew a line on the watering can and filled it to that point every time which made it much easier than measuring the water. Then using a watering can and a coarse rose, I saturated my plants from the top making sure that the soil and earth was well saturated and covered. I repeated the mixing process until all of my house plants were suitably saturated. I then personally left them for 10–15 minutes for that to work through the soil and then went back and applied a second dose to make sure that it really permeated through all of the soil. Some of my plants were very big; my Monstera for example is in a pot large enough that an entire watering can did not make it all the way through and out of the bottom so I carried on watering until I saw the water come out the bottom of all of my pots and ensured they were fully saturated. Once they had dried out a bit, I moved them back in the house and then complimented the treatment with a few yellow sticky traps to catch any established flies that were impervious to the nematode mix. It’s important to realise that the nematode mix attacks the larvae in the soil so won’t affect any flies have already started fly and there is no guarantee that treatment will get rid of all of them. The pack actually recommend treating 2 weeks later and I would presume that regular treatments would be the only way to keep them completely at bay as well as isolating and treating any new plants that you bring into the property. I notice the flies in my conservatory where I’ve got 7 house plants; the plants in the rest of the property don’t seem to have any blackfly, but I still treat them anyway. It’s also worth noting that you need to stir your mix in the bucket every time before you add to the watering can as it does settle to the bottom. So I made sure to give a thorough stir watering can I made and would scoop from the bottom to make sure that I captured plenty of the mixture. For me it’s really simple to use, the instructions are easy to follow and it’s easy to apply. I think the performance is very good but it is worth understanding that you need to do maintenance treatments and also supplement with sticky traps. It isn’t a case of one treatment gets rid of them all and you do need to keep up with regular treatments and bottom watering your plants really does reduce the wet soil on top that they like to breed in

Used this on my houseplants which have been plagued by sciarid fly for the last year. I had tried EVERYTHING!! -nothing worked, then I gave the plants a drench of the nematodes and used sticky traps, I did use a more concentrated mix as was instructed but, the next day there were 2 flies on one of the sticky traps and not seen another since!! - months later…. Still no flies!!! BRILLIANT PRODUCT!!

In the package you get this brown clump, doesn't look like much, but after mixing with water and pouring on plants and given a couple of days you can see how big they grow, so much so they can be seen without any zoom using the macro feature on my phone, you can even see them glisten with a torch light without the camera. Unfortunately I can't give them 5 stars, as they've been unable to entirely eradicate my fungus gnat problem. (I realise they only kill the larve.) The first time I used these nematodes it fixed the problem for almost a year and second time for half a year, now I'm going through a pack almost monthly, that being said the numbers are still massively reduced. I'm now using these in combination with yellow sticky traps and diatomaceous earth, which seems to be mostly working, just one or two stubborn pots, I might just resoil, the worms won't thrive in them. Probably the diatomaceous earth killing them before they kill gnats. So original I would give this product 5 stars, now I would say 3 stars, so I left it with an average of 4.

The only true way to eliminate fungus gnats at home.

ok

Goodbye fungus gnats! This product is amazing for removing any infestation and is great value for money. Very easy to use and effective at stopping the annoying flies around the house

This nematodes WORKS!!! Soon after I apply that on my pots, raised bed, and lawn. All plants looks much better. I noticed my garden was infested with leatherjacket. I found quite a lot of worm and crane fly. The plant stuggles in spring and over winter. WOW, it save my plants and garden. I found a paralyzed leatherjacket today in the raised bed. I did not remove it, since the nematode is multiplying inside it. Wonderful product. Have been looking for multipurpose nematode for a long time, finally found one. Will definitely buy again.

I use this on my lawn to get rid of leatherjackets. Definitely helps but not completely. Well worth it for the price though!
