Garden Pests and Diseases: wasps, 1 by DevilDogs

We moved here several months ago and found two different types of nests everywhere. Now with the warmer weather hitting, we have wasps literally coming out of the woodwork. It looks like they are nesting in the attic (see them going thru the vents), see them going into the gutters, my back deck is crawling with them. I have a 6 year old child and dogs, one which is allergic to bee stings and I have no idea if that translates to wasps. My DD is terrified to even go outside right now. I'm not exactly sure what these are but here is a picture of one of the wasps and I've taken a picture of both types of nests we've found. One is a paper nest, and one is mud.
What are these? Are they aggressive? What is the best way to convince them to leave now?
Thanks,
