yes... the soil knat eggs hatch out.. to these larve...I kill them at that stage with some BT... a naturally occouring killer of larvie. making them sick and unable to eat.. it's the active part of mosquito dunks.. and safer caterpillar killer.. I'd been disolving the dunks.. but the caterpillar killer is so much easier... but the dunks have the advantage in that the flecks of the dunk.. slowly release the BT over time.. so you get a tiny boost of it with each watering.. but application is uneaven.. the flecks often get in some pots more than in others... and it's natural
