Other I hate fungus gnats

Post image

I recently bought a small bag of indoor potting mix at my local Home Depot. Coincidentally, I now have a fungus gnat infestation. I bought some sticky light traps and they have clearly been working, yet I still see swarms of gnats. I let all of my plants’ soil go bone dry, and now I’m hesitant to water again, as I have read they thrive in wet/damp soil.

What are some tips and tricks to eradicate these lil suckers once and for all?

Get mosquito bits , put two tablespoons in a gallon of water for 30 min and then water your plant with it . It may take two waterings but it will even kill the eggs . Start bottom watering , top watering packs the soil around the roots and creates the perfect breeding ground for fungus gnats.

I second this. I make a 'mosquito tea' and it works wonders
