Wasps in Spring
Wasps in Spring are not as numerous as they are in the Summer and Autumn. This is because the nests are just starting and the numbers are low. In fact when the Queen Wasp starts the wasp nest she is on her own. It is not until the first batch of workers turn from grubs to adults that she has any worker wasps. These workers are sterile females and she will produce many thousands of these before the nest dies off in the Autumn/early Winter. When the nest eventually dies only the new fertilised Queens will survive the Winter to continue the wasp population for the next year.

What to do if you see Wasps in Spring
If you start seeing wasps in Spring then try and see where they are going in and out. This will give you the location of the nest. Then the nest can be treated. Wasp nests in the Spring time can be difficult to locate. When the nest is larger in the Summer then the entrance of the nest is much busier, solely because the numbers are so great and so easier to see and locate. A wasp nest cannot move location but they will change the entry and exit points if any attempt is made to block the entrance to a nest. This is often what people do when they see wasps going in and out of a hole. This is never a good idea and I have seen many bad outcomes, including people being badly stung, when this has been done.
