I've been raising B mendica for over two years now. They require extra heat and do better at my house with only minimal spraying. For me, I find they are more difficult to raise than many species, and I lose a few more L1 and L2 nymphs than some species. But as for the mating, I find them one of the easier species to mate. The females always seem receptive, and the males always show interest. I've mated every adult female, but I've had a couple that did not lay fertile ooths. I often leave the female and male together for a couple of weeks without issues. Then I remove the males for a while because some of them attempt to mate quite often. Then I put them back together for a while.
