when will i have male roaches!!!

[allaboutfish]

so i feed off all but 1-2 of my male roaches and then i went back to crickets for a few months. i now still have only 2 males with a million females and a million babies. when will i have males and at what size will they show gender?

6 months from baby to full grown - you can check their gender by looking at their abdomen. Female nymphs have one big section near their butt end, while males have equally sized sections all the way down.
