Maybe your betta is just mean.
I agree.
My crowntail Betta - Mr Crankypants - is very aggressive at times... I recently tried a couple of Clown Loach with him and he wasn't having any of it... I took them out after he performed a 4 hour constant "threat" - flaring them like mad.... when he finally took pop and missed, I took them out straight away... some things just won't ever get along with some Betta's and their unpredictable temprament...
However - despite Mr Crankpants's apparently very aggressive nature at times, normally he won't bother a single thing in the tank - including an elephantnose who is much bigger than he is, several Cory's and a shoal of Cardinal's who he just ignores normally. We keep 5 Apple snails all slightly above 1 inch in diameter and he never goes near them.
Maybe it's tank size and distractions though.... I imagine if a Betta is on his own in a small tank with just a snail, then that's definitely what he'd turn to, to investigate... unfortunately, Betta's "investigate" a little more roughly than most other fish though!
So Batman669 - I would say just try it with different snails. As each temprament of Betta is different, maybe you'll just luckily plop a random colour/type in and he just accepts it.
There is a particular variety called the Zebra snail which is a lovely tiny little snail (barely half inch across...). It's colouration is typically black bands on a brown background which is quite dark and non-attractive to most Bettas. One of my small 10 gallon tanks has two and they keep it absolutely spotless!
Try that and see if it works... they're normally very cheap - around 50p or so
