Hence and Thus

Do you put a comma after 'Hence' and 'Thus' in a sentence.

"Hence, we will be looking for this new bug."

Or is it

"Hence we will be looking for this new bug."

OR

Is it dependent on the publisher's style?

Okay, I found the usage online.

hence
adv hence [hens]
1 for this reason Hence, I shall have to stay.

2 from this time a year hence.

3 away from this place.
adv henceˈforth
from now on Henceforth I shall refuse to work with him.
