Where are the bats?

Deadly Bat Disease Set to Go Global

No one likes to have their sleep disturbed but for hibernating bats it can actually be deadly. Geomyces destructans is caused by a white fungus that irritates infected bats' skin, rousing them from their slumber and causing them to expend precious reserves of energy—often leading to starvation.

Since first being discovered in Northern New York, the syndrome has spread west. Now, an outbreak in caves in Oklahoma have experts worried it is poised to spread across the hemisphere.

Have not seen any bats in the sky near my garden. Could this be the cause? Hope not!
