Got Wasp and Bee problems. How is a better way to get rid of them?

Question:I live in Northern Utah. It's getting very hot now this summer. I seem to attract Wasp . Wondering if the Humming Bird feeder attracts them. They are coming and trying to feed on it. How can I determine where there nest is? I have wasp tracks two of them on the patio on different places. But they do not seem to get into them. What else can I do.? I am allergic to their bites.

Answers:
well, we used to put trays of beer outside. it attracted them and killed them, i guess?

but i'd agree with the other answer -- professional!
