Yes Yes!! The apple cider vinegar works great. They just seem to love the stuff and it kill the little bastards...!!
I also saw where you can put pure sand on the top of each pot and they can't get to the dirt below..?!
yes, the sand and perlite are supposed to have the same effect, it smothers the larvae.
