How long can the eggs lay dormant?  
 
Thanks again..................Dave

 In the study that I refer to they say that a normal egg will hatch within 4 weeks in suitable conditions but that all eggs hatch or die within a 6 week period at 20c.
Now remember that is only the eggs, the larvae have between 5 to 10 weeks and then move on to the the pupal and prepupal stages can take up to 3 weeks and then on to adult hood which adds another potential 4 weeks.
Assuming maximum range on all life stages it seems reasonable to assume that it could be 6 months of time that could pass before you could be sure of total mortality.  That assumes of course that a female does not lay more eggs.
