Do you need to have a bachelors degree to teach?

Yes, you do need a bachelors degree. Some may accept a GED but I think most will want a university degree. Let me know if you have any other questions!

Do you know what country they are talking about? If it's Thailand then they don't need to have a bachelors, but it will limit where they can work and how much they can make. They will also not be eligible for a long term visa and will have to make a visa run every month or so (can't remember the length exactly).

In Myanmar, you really can't teach without a Bachelor's degree unless you have a lot of previous experience teaching English.
