I have been working on different ideas to "excite" males that have been reluctant to start this season. This is one idea that has been working well and I wanted to share. I take a paper towel and place it with snakes that are actively breeding. I leave the paper towel in for 2 days. Then I place that paper towel in with a lone female for one day. After one day I leave the paper towel in and introduce a slow starting male. The scent from the paper towel seems to excite the female and she is receptive to the male. The males have instantly been more aggressive breeders. Usually locking up within the hour. Hope this information is helpful.
Good luck to all this season
