Fungus Gnat Killer Spray 500ml | Organic Protection Against Sciarid Flies | Effective for Houseplants, Seedlings | Safe for Indoor & Outdoor Use | Targets Adults & Larvae | Eco-Friendly Formula

Easy to apply, with no odour, plus the plants seem unaffected. But most importantly, it see seems very effective against compost flies: a tsunami of flies turned into a trickle in a few days after initial application, and a second use stopped them completely. Recommended

Sadly this item has not been successful for me.

After two weeks the fungus fly have gone completely.

Seems to be working as no visible sign of gnats since I started using this. I first water my plants and then after a few hours spray the soil. Used with sticky fly traps, which seem to have only caught one or two stray flies.

Great product that worked in a few days

Kills the fungus flies as advertised

Frequent thorough sprayings has not eliminated the fungus gnats. I shall return to using one of the more toxic sprays which can stop the damage in one spraying.

Didn’t work at all. Used a whole bottle and no decrease in flies. Used Alongside the sticky fly trap thing which did cath plenty. Soils still full of them though despite daily spraying for a week.
