The description sounds like hornets. They are probably building a nest in your carport. On the other hand, I'm not sure hornets hover very much. They usually move pretty fast.

If they are indeed hornets and building a nest, you need to find a way to take care of it early, before three hornets become a hundred.

I've been fighting plain wasps a lot so far, trying to build along my front porch. They are less aggressive and I can take them out with Wasp/Hornet killer that sprays a foam about 10-15 feet.
