Delaware City in New Castle County, Delaware — The American Northeast (Mid-Atlantic)
Small But Mighty
They seem scary to many people, but a world without bats is scarier. Bats eat millions of flying pests each night, helping to control mosquitos and moths and saving farmers billions of dollars in pesticides.
White-Nose Syndrome [WNS] Threatened Bat Populations
WNS is a disease causing mass die-offs of bats at hibernation sites, including Fort Delaware. The disease was first detected in the United States in 2006 and killed millions of bats in the first 7 years. Bats affected by WNS have been detected in 33 U.S. states and seven Canada provinces as of 2019, and the disease continues to spread at an alarming rate.
WNS is caused by a fungal pathogen called Pseudogymnoascus destructans (Pd), which grows in cold, dark, and damp places. Pd erodes the bat's skin tissue and causes more frequent arousal during hibernation; resulting in cellular disruptions, dehydration, starvation, and often death.

What Does WNS Look Like?
Infected bats may have a white growth on their snouts, ears or wings, or may exhibit unusual behavior. However, sometimes they show no visibile signs, and laboratory tests are needed to detect the fungus.
