LAVA-LITE NO-GNATS is a natural volcanic top-dressing offering effective fungus gnat control and natural pest control for houseplants, pots, containers and greenhouse plants. This houseplant top dressing is ideal for indoor plant pest prevention.

Fungus gnats thrive in damp compost and lay their eggs in the top layer of soil. NO-GNATS creates a dry, aerated, moisture-wicking barrier that discourages gnats from landing and stops them accessing the soil to lay eggs.

100% natural, pH-neutral, non-toxic and safe for pets, children and wildlife. Once finished, the product can be mixed into soil to improve drainage and aeration.

⭐ Perfect For

  • Houseplants affected by fungus gnats
  • Pots, containers & indoor planters
  • Seedlings & young plants needing protection
  • Greenhouse plants with damp compost
  • Gardeners wanting a chemical-free solution
  • Preventing gnat infestations before they start

⭐ Key Benefits

  • Creates a dry, airy barrier fungus gnats avoid
  • Helps prevent gnat egg-laying in soil
  • Reduces surface moisture that attracts gnats
  • 100% natural volcanic stone, pH-neutral & non-toxic
  • Decorative top-dressing for indoor plants
  • Doubles as a soil improver once finished

⭐ How To Use

Remove any loose debris from the top of the soil. Apply a 2–3cm layer of NO-GNATS evenly across the soil surface, covering the entire surface. Water gently to allow the granules to settle. Reapply after heavy watering.

⭐ How Much Do I Need?

  • 1L pouch — covers approximately 3–5 small pots (up to 12cm / 5 inch) with a 2–3cm layer.
  • 3L pouch — covers approximately 10–15 small pots, ideal for a larger collection or bigger plants.

As a guide, allow roughly 0.2–0.3L per 12cm pot for a 2–3cm layer. Larger pots need proportionally more.

⭐ FAQs

What is LAVA-LITE NO-GNATS? A natural volcanic top-dressing that creates a dry barrier on your soil surface, helping to prevent fungus gnats from breeding.

How does NO-GNATS work? The volcanic minerals absorb excess moisture and disrupt the conditions fungus gnats need to breed.

How long until I see results? Most users see reduced gnat activity within a few days, with significant improvement after 1–2 weeks.

Is it safe for pets and children? Yes — 100% natural, pH-neutral and non-toxic.

Do I need to reapply it? Reapply after heavy watering, as this can disturb the top layer and reduce its effectiveness over time.

Can I use it as a preventative measure? Yes — applying NO-GNATS before you see gnats can help stop an infestation from starting in the first place.

What happens to it after use? It doesn't need to be thrown away — it can be mixed into your soil afterwards to help improve drainage and aeration.

⭐ Sizes available: 1L pouch, 3L pouch

It’s a success, if you hate little flies just buy it!

Oh my God, it’s a must because, I can’t live with hundreds of tiny little flies.. I hate them!! 😂Anyway, I’ve used all of the at killer on my plants last night and there’s zero Gnats on my windows and sticky plastic plant traps. Therefore, it’s a success already!! 😃One very happy customer.

The only measure we tried that stopped gnats on all of our indoor plants.

Does the job

The gnats are gone!









I bought this as my landlord left me some indoor plants but I didn't like the little squatters they attract. Gnats.So I let the plants dry out completely as this stems the larvae hatching and then repotted in fresh compost before adding this on top.So far it's doing its job and there has been no annoying little flying pests getting in my face.In order to protect it's use water from the bottom.In all I'm pleased with this and this bag has done eight small to medium sized pots with plenty to spare for my two large ones to go. As you can see it has absorbed a little moisture but that's fine.

Working really well

Seems to be working, ordered another bag to do all of the houseplants.

Vast improvement!

Better, almost perfect. This is certainly preferable to chemicals or the stink of neem oil, and the gnats have definitely reduced. There are still a number of gnats in the affected plant with smaller guys suggesting that reproduction is still possible but will probably not!. This review comes a couple of weeks after purchase, so there’s still time for a total victory. Redhead VS Gnats continues!

worked perfectly

coming back a month later to report this worked superbly, so pleased and no need for pesticides. did as it said (probably a bit more than half an inch) and added a fly sticky pad as well to each effected pot. anyway a month later, no gnats at all. would buy again!

Really does the job!🪰

When I first added this on my plants, it reduced the fungus gnat issues I was having, but didn't fully stop them, and eventually they just came back. Bought another bag and again, briefly reduced fungus gnat population but then they came back. This was over the course of several weeks.I was about to use BTI treatment, yet before I did, I noticed my sticky traps were getting fewer and fewer gnats, and eventually... the problem was gone!I don't know if it was due to this product, the sticky traps, or a regular regimen of blocking drainage holes with water, but somehow the gnat problem is over. I think this contributed, but it is only one element. Consider using this, sticky traps, BTI treatment, AND watch out for watering and gnats escaping via drainage holes!

Give it time - it does work really well

I saw some bad reviews of this product so wanted to write my own. We have had small flies all over our house plants- which we’ve struggled to get rid of. This product plus the yellow sticky fly catchers worked perfectly. It does not happen over night - you have to give it a week or two. Plus you have to put the sandy stuff quite thickly on the top of the soil. But we are now fly free!! I will definitely use it again

It Works as advertised

The product to date is working well, since applying a coating to all my indoor plants, I haven't seen a knatThank you

Good for the environment.

Not used yet, doing it later today. So fed up with the tiny black flies, and the larvae in my outdoor plants. I bought cheap compost so that's what you get in it. Got Snowdrops in and don't want them ruining. One litre bag should last a while and kill them off for good!

Brilliant stuff!

Great stuff, have bought twice.I was plagued by plant gnats. Threw my old plants out not realising could get this stuff.A good layer is vital and don’t forget the middle of the plant, ensuring all well covered, carefully press it down.Completely natural, easy to use.

this is good stuff

It may be us however we have still had a small issue after usually this. Previously used liquid which was instant. However it is working, just slower.

Would recommend

I used this after completely changing soil in worst affected plants and in conjunction with anti gnat soil treatment. It appears to have done the trick and plants are looking healthier. It also looks effective, especially on my succulents.
