Abstract

We describe a hospital infestation by 2 hematophagous ectoparasites of cliff swallows that nested in the window eaves. Breaks in window seals allowed entry of swallow ticks and swallow bugs. These pests emerged in large numbers in patient rooms, hallways, and stairwells; 17% of the ticks fed on humans.
