From the entry

Any living creature damaged by a bat swarm continues to bleed, losing 1 hit point per round thereafter. Multiple wounds do not result in cumulative bleeding loss. The bleeding can be stopped by a DC 10 Heal check or the application of a cure spell or some other healing magic. Bat swarms dwell in large caves, ruins, or even city sewers-anywhere they can find darkness to hide in during the day and a supply of food to feast upon at night. They are only encountered outside in a group at dawn or dusk, or when they have been startled and forced to flee their lairs.
