Nick,
From what I have been reading on posts in this forum, winter has been mild in California with no particular excesses... so it could be a good year for wasps so you saw them on your yard.
If weather keeps mild, no reason not to believe that when the season reaches pollen time (May/June) many pollinator insects will visit your figs... you need to watch
Assuming the Mamme crop in one particular area ripens 1,000 fruit
Then the number of Profichis ready to accept the insects exiting the Mamme, will be 4, 6,..10/12 times
those Mamme.. this is to say that there will be plenty (if weather helps).
Search around your neighborhood an look for figs.. There will be not enough leaves (I hope) to hide the fruit. So it will be not too difficult to locate if they are there... (Caution: watch the traffic)
Believe you stand a good chance to get your figs pollinated by wasp from someone else caprifig
Watch you yard.. if they are abundant, some may already be visiting your trees.
Watch for spider webs circling the figs/ trees.. look against sunlight.. it's easier to detect the web
Wasp predators know well in advance of humans when the wasp comes and set their traps in waiting.

A pack of still green Violetas with the spider webs set in waiting for the coming wasps in June/2015 .
