UH OH...wasps nest under my wicker table and all around my porch...

FRIGGIN A! I'm so upset, the porch is where we hang out the most in the summer, but I guess because the weather has been so hot and we haven't been out there much, the wasps have moved in. I have a wicker set on my porch that we use a lot and I was just out there and saw a whole bunch of wasps going under the table and sure enough, there's a nest there. Then I noticed that they are also congregating in the gutters above the porch, so basically my porch has become wasp territory and I don't know what to do!
Does anyone have a good exterminator in Suffolk or can we take care of this ourselves? I'm so upset because I really wanted to sit out there today with the kids
