Create an Execute SQL task. Have it run first. For the sqlstatment do.

Truncate table DestTable

Using truncate table is better then using delete as it ignores all the indexes and just removes everything.

For a little background info. I will try and explain why you should use truncate table instead of delete table. Delete table is a row based operation this means that each row is deleted. Truncate table is a data page operation the entire data page is delocated. If you have a table with a million rows it will be much faster to truncate the table then it would be to use a delete table statment.
