soil fungus gnats
I have what I think are soil fungus gnats in my seedling area under the lights in my basement. (They look like fruit flies) When I noticed them a couple of days ago, I started trying to dry out the soil a bit. Then today I noticed a white fungus (?) covering the surface of the soil on just a couple of the seedlings. I scraped this off and added some dry medium to the top, hoping to absorb the moisture. I understand the larvae can feed on the roots of my seedlings and cause damage. I read somewhere that you can use bt on soil gnats. The bt I have is meant for cabbage moths. Is this the same/ will it work on them? Any other suggestions other than allow the soil to dry out?
