I just found out my pots in the basement have fungus gnats!!! I don't remember what you all reccomend for them!

I'm sure you'll get lots of suggestions and it depends whether you want to use "chemicals", organic controls or household remedies. But basically it suggests you're watering too much. What is the growing media in the basement, is it soilless organic?

I just got beneficial nematodes which work best on large infections, imo.

I've used 1 part hydrogen peroxide to 3 parts water (I think)...soil may fizz but the larvae will die.

Also Dawn dish washing soap in water.

Mosquito dunks.

And lots more...right now I'm using the nematodes in my outside gardens.

For my seed starting this year, I have been using Miracle Gro potting soil (not seed starting mix), and I tried something that someone here on ATP suggested, which was to pour boiling water over the mix before planting.

The boiling water moistened the mix very nicely (which cooled down quickly for planting), and thus far (it's been over 3 weeks now) we've had only one or two gnats, which I am convinced came in from outside. (There are a LOT of gnats out there.) The ones that came inside were trapped on a sticky yellow trap I put up next to the pots.

So far, so good; it looks like this year, I won't have to listen to months of complaints from DH, in the form of one pun or another on "gnat".

I'm late, sorry!
It's a common garden soil. The porblem is too much water, one seedling rot and died.

I was panicking so I sprayed with a chemical insecticide I have. They seem gone, and since we're getting nice temps and a bit of sun I put the pot outside for a few hours so the soil dryed. I didn't see any in three days. I'm putting on my notes the things you all suggested many thanks!!!!!!!

Sabrina, just to clarify, by common garden soil do you mean taken from your garden and used in the pot, or is it something you bought?

Sorry, it's a bag I bought.

I thought so but wanted to make sure because soil from the garden doesn't have the characteristics to work in a pot, or at least not on its own.
