Wasps in shed, no nest visible, what to do?

Question

I have one of those rubber maid storage sheds. The wasps seem to be be building a nest in the hollow portions of the supports. There is no way to use a wasp spray into there. They access it at different points (door jam, another crack, etc). I'm not sure how to get rid of it. I thought about removing all belongings from the shed one night and using a fogger. Are there any foggers that would work? Any other suggestions? They're really getting out of hand!

Answer 1

caulk'em in and they'll die off

Answer 2

they have probably collected around a carcass of a small dead animal you will need a bee outfit to find the source of thier interest and remove it then they'll go away or also find the nest and treat it at night wasps come home at night and you can get them all only then. if you treat for them during the day they will be very mad coming home to a sacked home and then they turn to stinging mad wasps.
