Fungus Gnats!

SueCT · March 27, 2016

I was so happy to have an indoor herb garden this winter. I was surprised how well they did under the lights I usually use for my seedlings.

Well I started my seeds last week next to my herb garden, and most have germinated. The last couple of days I have started to see fungus gnats. I am concerned for my new seedlings. Is it worth fighting them with watering in BT or should I just buy tomato plants again this year? I have not have insect, fungal or other problems with my seed starting in 5 or 6 years. I have read it takes weeks to get rid of the gnats using BT. Would it help the tomato seedlings to put the herbs outside and let them go if they are not hardy enough, like the Basil? I don't have time to spend weeks on getting rid of the gnats and then maybe still have to restart seeds and have good sized plants in time to set out.
