What do dirt dobbers eat?

Spiders mainly. if you very carefully scrape the top off of a mud daubers mud nest you will find individual chambers. in each chamber they lay an egg and place a spider for the first meal of the young dauber upon hatching. they seal up that chamber and do it over and over. when the young dauber is born he eventually chews a hole through his chamber wall and leaves. if you have a spider problem dont swat the daubers! daubers are docile creatures and will not chase you down and sting you when you get too close to their nest like other wasp varieties. spiders are important, too, for keeping the numbers of other insects in check. its natures system of checks and balances at work. they all play a vital part in the big picture.
