bugs!

[beagle]

For some reason this year we have several bug issues that I dont know what the best way is to deal with.
First, we have wasps which have built a nest in our swim dock. They have strategically placed it underneath the planking yet on top of the float.
Secondly, we have two types of wasps/hornets flying low over our pearched beach. One type is a hornet with black & white stripes. The other likes to dig holes in the sand and then bring other dead bugs to bury. I have been stung by not sure which.
Lastly, for the first time ever, I am being bitten by what I think are no see ums. They are leaving blood blister like bites by my ears and along my hairline even when I am on the screen porch.
Arrgh!

Any advice appreciated!
