First of all, welcome to the forum.
This is a good place to start, full of information.
There are also reports of introduced flytraps in Jamaica, another place that doesn't see much variation in temperature, but it is a few degrees further south in latitude than you. Those traps, and yours, will likely go into a mini dormancy based on light cues only, and yours could benefit by putting them in a spot where it may be darker and cooler in December, January and February when your temps are the coolest. I wouldn't suggest putting them in the fridge, but it is a possibility to give them a good dormant period.
Everything happens for a reason. Sometimes the reason is that I make bad decisions.
