Bloom & Bud Fungus Gnat Killer for Indoor Plants (1 Litre): Ultimate Indoor Plant Protector for No Gnat Pot Topping with Gravel Mulch Systemic Granules|Plant Gravel for Gravel for Indoor Pot Anti Gnat

Great itemStops the gnatsWorks a treatExpensive but worth every pennyWould buy again

Worked for a time, but bugs were back as soon as I watered the plant

Works so well, good value for money and doesn’t smell. The plants are happier and it was really easy to use. Stopped the fungus gnats straight away

There appears to be a reduction in flies, but mould has started to grow on the wet pellets.

I first tried a spray from another brand. The fly population actually increased.So I tried this product. I’m having huge issues with those tiny house plant flies. They just won’t die! I followed the instructions for this gravel poison and the flies are still around after 2 weeks. They are still breeding in the top layer of the product and hanging around having a great time. I just bought some of those yellow sticky things and didn’t realise how many flies were still around showing how ineffective this product is. Such a waste of money

Found this to have really help deter little flies which set up camp in flower pots. Hasn’t seemed to disrupt growth of plant in say way, doesn’t smell either. Would recommend.

I definitely recommend this product. I had tried other was to get rid of the problem with out success up till I used this.

I wish I bought a proper fungus gnat killer. This is just a fine gravel.I've had more luck catching the gnats on the sticky traps you poke into the soil around the plant.This product is sadly not worth the expense I paid.Not at all impressed.
