Pyrethian powder for soil gnats???

Even if you have seen gnats flying around your plants, but the infestation hasn’t had any visible effects on your plant yet, it’s important to deal with the problem as soon as you notice fungus gnats.

You can try trapping the adult gnats by placing yellow sticky tape (available here)or sticky cards all around your garden. Gnat larvae, on the other hand, pose the real problem. First of all, make sure the top several layers of soil are allowed to fully dry. You will have to pause your normal watering schedule for a couple days – but it’s worth it. When the soil has dried, make a mixture of 3% hydrogen peroxide and water at a 1:4 ratio. This won’t injure your plants, but it will turn into oxygen and water (that, as you know, are beneficial to the soil). This will keep the gnats away while simultaneously helping your plants out.

To help speed up the process of ridding your plants of this pest, bring in a fan and have it blowing over your soil to help dry it up more rapidly. It also helps keep the tiny fungus gnats from flying around properly, therefore reducing the amount of eggs they are able to lay. A commercial product like Bug Blaster will always to the job. If you want to make sure to kill them all buy something like Bug Blaster.

If you want to be particularly thorough, you can apply some food-grade diatomaceous earth over the areas of the soil that are exposed. This will kill the fungus gnat larvae, keep future infestations from occurring again, and will speed up the eradication process. Diatomaceous earth is organic – it’s simply made of fossilized shells! It kills insects effectively by cutting into their exoskeletons and draining out their bodily fluids. Luckily for you, it is not dangerous for people or pets – you could even consume it and be perfectly fine.

Another way of destroying larvae that are living in the soil is using an actual pest treatment that contains the Bacillus thuringiensis bacteria. Bacillus thuringiensis sometimes referred to as “BT” or “BTi,” is a type of bacteria that creates a larvae-harming toxin. It essentially disallows them to eat.

The great thing about this bacteria is that, while it wreaks havoc on the tiny larvae, it won’t cause any problems for your plants or their roots. It also poses no threat to your own health. It is highly selective with where it focuses its harm – and it focuses almost exclusively on larvae. Make sure to crush the little pellets that you can buy and then sprinkle the resulting powder onto the soil from there. Dry formulations generally function better than liquids. When you do use this treatment, water your plants plenty afterward. This is a substitute for the hydrogen peroxide/water mixture that was described above.

Once you have eradicated the fungus gnats from your garden, make sure to change your watering habits. Clearly you were overwatering, since that is what must have attracted the fungus gnats in the first place, so make sure to avoid this in the future so you won’t need to deal with another fungus gnat infestation – or worse.

I took this from an article I found it should help you rid your plants and soil of those pesky bastards.

Good luck..

Garden safe works pretty well ... I just had a outbreak in some new plants so i just sprinkle over top of soil and leave for a couple of days before next watering.
Scratch a little into top soil and you are set. Works on drier soil when applying.

You want it to stay dry after application.
