?? Fungus Gnats -- Controlled With Basil, Lavender, Etc.?? - General Gardening - International Cannagraphic Magazine Forums

I've read that Lavender, Basil and other herbaceous plants along with some ornamental plants such as marigold do an excellent job of repelling fungus gnats. I wonder if growing these very near to or in the same bucket as the cannabis plants is effective at eliminating the gnats and other nasty pests.

Has anyone tried this technique in the cannabis community? The herbs smell nice, look great and we can eat them. It seems like the perfect solution if it works.

I'm asking because I have a fungus gnat infestation. Soap, neem oil and H2O2 are working but IMO it's even better to simply repel the little bastards with plants that are beneficial to us anyway. There's nothing tastier and healthier than garden-fresh herbs that are organically grown.

Oh... and these plants repel aphids and other nasty critters too. I initially asked because of my gnat problem.

diatomaceous earth works well for me.nice layer on the soil helps.
Ive noticed that keeping the humidity on the lower side helps.
Also, i noticed keeping the pots on the drier side helps.

Im sure the pros will be along shortly, so wait for them to chime in.
Good luck mate.

Thanks, yes, I'm sure DE would help. I've yet to try that.

i am going to try it actually. I started just doing compost teas which pretty much wiped them out for me. I also thought it might be worth having some pots of lavender/ marigold in there - worth a shot.

Compost tea kills gnats? I'll research that. I know certain bacteria do.

I did a few neem sprays also but yeah the compost teas built a soil life up to help eliminate the larve. Check out the book 'teaming with microbes'.

Okay, thanks. I'll find that book.

I bought a Fly Ribbon 4 pack because I had a stupid house fly in my place a while back.
I then decided to put 2 around my plants. The house fly got caught the next day and
a few fungus gnats that the H2O2 didn't take care also got caught so that's cool.
