What species of wasp is this? And how to get rid of them?
These are European paper wasps. 

(They look very similar to yellowjacket wasps but you can notice the antennae; they are brown here whereas they are black in case of yellowjackets. There are other subtle differences too.)

See this post on Gardening &amp; Landscaping stackexchange about getting rid of wasps.

(This part is probably not really on-topic here and I don't want to copy-paste an existing answer in another stackexchange site.)
