Hello, these days I prepared a paste for fruit flies and does not fall any. Maybe I should wait until the pasta ferment or what? In my country they not sell and It is very costly to send live animals by mail and I have to catch them from the backyard of my house. Here I leave the ingredients with which I prepared it (vinegar, ripe banana, peach juice "tetrabrik", sachet of yeast, oats and an envelope of mashed potato powder). Please help! I was giving myself oothec of mantis and soon they will leave.Thanks in advance.
