discoid and orangehead cannot climb glass. here's a link to a list of just about every type out there and also an article about keeping/breeding.
Not sure what ones you may or may not be able to get shipped there. When tropicals are shipped up north there is little chance of them completing their lifecycle, therefore not a a pest, but in other tropical islands, countries there is probably some restriction. As Matt said www.blaberus.com is a good place to begin. I think www.cricketfood.com also (used to) sell some non-climbing species. Btw, glad you are aware of the local spraying!
