I have a pinstripe that would not lock with any female no matter what. All the others ahev locked many times in the last month or so but this guy just wasnt cooperating. I pulled him out and put him by him self for about a week and then it went from rain to below zero and snow. I spot cleaned the tubs (to leave the scent of other males alone) and just disinfected the water bowls. Then sprayed everyone real good and put that pin back in with a female. Low and behold, he was locked FINALLY with a female yesterday!
The wrong female of course lol, but at least now i can put him to the one I really want him to breed and he should do his thing.
If you let the temps fluctuate and any of them are not breeding when you do pair them up, try removing the water bowls for a few days to a week. While they are seperated. Then put them together and spray them down real good like a rain storm and replace the water bowl. The removing of the bowls has more of an affect than just reducing the amount of bacteria spread from snake to snake. In the wild they have a dry season and then they breed during the wet season.
Being in california you may need to play around with the "weather" in your snake tubs a little more.
