Breeding Tips?

Its January now and I still Haven't seen a single lock-up. I'm getting very frustrated. I have tried every trick I know and thought I'd turn to you guys for help. so far I have cooled the breeders, light cycle has been adjusted, males have been placed together but they aren't interested in battle, I have tried wet sheds, skipping cleanings, bumping up humidity, and feeding the females a good size meal before introducing the males. so far nothing has worked.
I suppose it is possible that I am just not seeing them lock. I have to go to bed early because of work so I can't check them at night. However I do check first thing in the morning and nothing. the only difference from previous years is that now the snakes are in my house where as before they were in a building outside. Could being inside have that big of an effect on them? the move was back in june so they are well adjusted in their new place. I'm just not sure what to do next so if anyone has any advice that would be great.

I have heard and even seen in a couple of my animals that having a change in environment can throw them off their game. It is possible that their are things in the house that are a bigg enough difference that your snakes feel like their environment has completely changed. Then again they may just be taking a year of.

How many of the females you are breeding this year bred last year..they may not even go this season..then again they may just be going later to to average rain fall being lower than this time last year.. there are thousands of reasons they might not be breeding.

i have about ten females going this year. three of those are ones that bred last year. and one is one that bred the year before that but took last year off. I'm going ahead and bumping temps back up in the hopes that that will get them in the mood.
