Fungus Gnats

Hi! My first post!

I recently read somewhere that you can get rid of fungus gnats that plague houseplants by mixing 3% hydrogen peroxide with 4 parts water and treating the plant when the soil has dried out. It also says that you should buy hydrogen peroxide that has no additives. However I can only find a 3% solution used as a mild disinfectant and which contains phosphoric acid (E338) and phenacetin.

Has any one else tried this treatment with any success? If so did you find a solution for sale that has no additives? I would love to rid my plants of this little blight but don't want to harm them in the attempt!

I have also read that sprinkling cinnamon over the soil gets rid of the gnats but havn't tried this yet!

Thanks

 

Perhaps cinnamon would be worth a try first while you are trying to source other solutions to your problem.

Found this on the BBC website, could it be any assistance to you?

Hope this Helps!
