A call arrived from a local hospital where Argentine ants had been a long term problem.  As usual with this species, the ants were seen trailing in kitchen, pantry and break room areas where they foraged for food and numerous ants were frequently observed as they trailed to various locations. They were also appearing in patient rooms.

Ants are generally viewed as tolerable insect intruders in comparison to cockroaches, which are usually seen as being disgusting. It was when these ants made their way to the cardiac intensive care unit patient rooms that the problem became serious enough to garner the attention of management.
