Try regular vacuum - that should mark unused space in those tables as
reusable so the table size should stabilize instead of growing.

If you are always creating the same tables then could you might (if there
aren't locking issues) be able to set up empty copies of the tables and do
something like:

truncate table scratch_test;
insert into scratch_test select * from test2;

But the bigger question is what is it that you do that is creating all these
temp tables so often? Perhaps there is a completely different better
alternative.
