Fungus Gnat Killer Spray 200ml | Organic Protection Against Sciarid Flies | Effective for Houseplants, Seedlings | Safe for Indoor & Outdoor Use | Targets Adults & Larvae | Eco-Friendly Formula

It seems to be working but time will tell. Needed to also put gravel on the soil surface as part of a thirty day treatment plan

I have been using this for several days, the fungus gnats don’t seem in the least bothered, even when sprayed direct. If anyone does want to try it, please note that the spray gun has a very small button at the bottom which you need to click to get it to work, then click back to close. It took ages to work this out! i am still catching tens of the things on sticky traps and in my window every day. I don’t feel this has done anything. The only good thing is it’s odour free.

After trying various compost toppings and sticky labels with little success i have found this spray made an immediate difference and no flies have emerged from the plants I have been treating. I missed one and after seeing a few flies for the first time in a week I realised the missed plant was the source. I am still using the sticky labels but highly recommend this spray. I do regularly spray the surface of the compost and find the small bottle lasts a suprisingly long time even though I think it is overpriced considering the ingredients. I have just bought a second and feel I will finally get rid of the scarid problem in my house plants that I've had for years.

It is effective but you need to soak them a few times over a few weeks.

Unsure if it works. Sprayed directly onto a fungus gnat and just flew off so no idea if it's done the job. Yellow sticky things seem to work better and cheaper...

Disappointed in it

The standard bottle as shown is very small at only 200ml - my mistake for not noticing this! The bottle also comes separately from the spray application. My spray application did not work from the outset rendering the product virtually ineffective. I now have doubts that this system and product will destroy a sizeable colony of gnats in any event I opted later for a box of chemical grain which now appears to be working.

It seems to have helped get rid of most of these pests, but I have also applied nematodes to the soil of my pot plants. These worked well last time I used them but I wanted quicker results this time round so going for the double whammy! Easy to use, although the catch on the spray trigger was one I'd not seen before and small enough to be almost invisible, although an excellent idea in retrospect.
