There's good solutions on Google that can be made up to kill them an easy one I know is to remove the top layer of soil and replace with sand the eggs that where left can't come through and the other don't want anything to do with sandhello today is one of my regular watering days but I decided not too water and wait a day for two reasons
1 my pots are still heavy
2 I got fungus gnats bad in my tent from the soil plants
