is a moat a good idea for escape prevention for L.niger
i plan on using a lone queen so her first workers would be really thick (in ant standards anyway) and i dont want the poor suckers to walk in and drown?
if it is a good idea should i use water or cooking oil as i heard somewhere that that is a a better option and i dont know whether or not it is a good idea as it is thicker and corpes could possibly float and create a morbid bridge
