Considering moving my snakes into the garage.

[Bogertophis]

For what it's worth, I used to live in the California desert & raised all kinds of rodents in my garage, both for sale & to feed my then-huge family of snakes.
I've never kept snakes in a garage, but let me just add, that was a 4+ car garage (that I did pull my van in & out of most days, as I went to work etc), BUT it
was a "finished" garage....the walls & ceiling were well insulated & I personally insulated the garage door also, & I had A/C installed (a "swamp cooler" actually,
but you'll need A/C) on a thermostat control, & also had "up-ducts" to keep the air flowing up & out). Even in So Cal, winters got cold (I was in the "high desert")
& for that I insulated the rodent cages...they make enough body heat to get by, unlike snakes, & as already mentioned, excess heat is generally the bigger danger. (the rodent cages were also NOT near the garage door, btw)

One thing I haven't heard anyone mention is power...as in when storms knock out your electricity. In a hot or cold garage, you are going to lose animals unless
you also have a generator ready to run. It's far less a problem in a house, simply because there is more air space...it takes much longer to get dangerous so you
have more time to mitigate until the power is on. So you may be running A/C in your garage in the heat, but think how fast your garage is going to be a death-
trap for your snakes if you lose power? And what if you aren't home to even know about it? If your garage is not even insulated...???

And as I mentioned before, don't under-estimate ants or other pests. Even in my house I had invading ants kill a cute gecko...they entered his cage presumably
for his mealworms, but bit him too & he quickly died.
