Worms

grubs??? garter snakes don't eat insects.... fish, amphibians, worms, slugs, leeches, rodents, and occasionally odd stuff like roadkill is eaten by them. I have a pic of one eating a roadkill bird!!

I'm betting by grubs they mean slugs.

Thats not entirely false. I have kept eastern garters before that have taken grasshoppers readily, they were just small yearllings tho, and i have witnessed in the wild a young garter eating and orb weaver spider a year or two back, so it is possible but recently i havent had any success, so if u insist on grubs go for it but it will most likely be difficult.

In the late seventies I kept about a dozen Gartersnakes (T. s. sirtalis, T. s. parietalis, T. radix, T. sauritus nitae) in a very large terrarium.
In this also lived a few lizards (Podarcis sicula) that were dumped at my place.
This all went well. The lizards were always basking on top of the snakes
When I gave the lizards grasshoppers or crickets or mealworms, there were often one or two garters that caught one of the insects and actually ate it.
But I do not consider it as "normal" food for Gartersnakes.
But I can imagine that they eat them in the wild so every now and then when there is nothing else to find.

when I was young and had just started keeping snakes, I had fed some flies to a garter....they came ouit the back end looking just like they did when they went in...looked like they couldn't digest the exoskeletons...kind of odd when they can digest bones and teeth...
