Gnat Off (Sciarid Fly Killer) 250ml

At last, an easy, organic way to get rid of those pesky sciarid flies that doesn’t cost the Earth! We take our hats off to Hydrogarden Wholesale who've brought this product to the Hydro market, it was much needed and very welcome.

Apply to tanks or irrigation equipment at 1ml per litre and the little critters die off in short order, it's still worth using the sticky fly traps to mop up the adult fungus gnats and monitor for re-infestation.

Great product - highly recommended.
