Course salt lightly sprinkled at to keep it on top of the maggot crust. Don’t just pour it in and have the flow of salt break thru the crust of maggots.
Good luck keeping flies out of your outhouse, or anywhere for that matter. I would think the maggots would disappear soon after turning to flies.
Never really noticed them in the box before and haven’t noticed maggots in last few years I’ve had the outhouse. I don’t really know what’s normal, maybe I’ve just missed a batch of them every year because I’m only here every few weeks
I read this could make chloride gas with what’s in there already. Seems like it would just go up the vent though so maybe chemical warfare is on the table…
