Primarily Spiders, but I would figure anything small enough to carry back to their nests.
We called them dirt daubers. They are a type of wasp that is almost completely black in color. They build an enlongated "nest" out of mud and attach it in your garage, overhang of your roof, or anywhere they can put it where it is sheltered from rain. They lay their eggs in the nest, stuff it with stunned and paralyzed insects (they really like Spiders). These insects are food for their young when they hatch and are in the pupa stage. Dirt daubers have a stinger that they use to paralyze these insects but I have never heard of them stinging a human being.
Mud daubers live for a total of one year. Mud daubers are slender wasps that are known for eating black widow spiders.
Mud daubers are solitary wasps, so it is very unlikely that they will sting you (unless you do something like trap one in your hand). Unlike hornets and yellow jackets, mud daubers do not defend their nests.

Wasps known as mud daubers...
Almost any where in the world
Mud daubers can be prevented by using traditional wasp repellents. These can be purchased at a retail home improvement store.
The scientific name for a dirt dauber is Sceliphron caementarium.
Mud daubers are a variety of wasp which build their nests out of mud or use the nests of other species of wasp. Mud daubers which survive the cold months are immature individuals which spend the Winter in the nest.
Yes.
Yes. I just saw a mud dauber flying around and landing with a black widow underneath it. I was googling around for the same answer and learned that mud daubers eat spiders which explained what was going on.

Yes, they are found there.
