I have a fungus gnat problem with my indoor herb plants and would like to apply Bacillus thuringiensis. Yesterday I bought six Mosquito Dunks and last night I cut off about 1/3 of one and put it into my 2-gallon watering can to soak overnight as I've read that's good practice.
Yet my plants don't really need watering right now, and I know that over-watering provides a perfect environment for fungus gnats!
So...should I water anyway, with the understanding that this particular watering with Bt soaked in will be helpful against the gnats? Or should I wait until the plants really need water? Though I'm hesitant to wait because I've been seeing the gnats for two weeks already (it took a while for what was happening to sink in!) and I know infestations can get really bad quickly.
Any advice would be appreciated.
