>> I dont want to hibernate them as just pets not a breeder(2 butlers garters unsexed but think by size a pair) so will just use overhead heat all winter till summer comes.
I don't breed my solitary male either, just hibernate because sometimes it seems to stimulate his appetite in the spring (he's gone almost a year without food in the past--I figure if he's not going to eat anyway, I might as well keep the temps low).
>> Though I cant say for sure they seem to enjoy "basking".
Many garters tend to be more diurnal than kings and milks, but I find them at night too (road-cruising). My captive is sometimes seen basking, especially after a large meal.
I was leaning towards overhead heat but figured good idea to ask keepers that have had garters for awhile.
I've had mine for 10 years now, but it's the only snake I've kept, and there are folks here much more conversant in garter husbandry who may swear up and down by UTHs for all I know.
