The unassuming bat plays a vital, often unseen, role in safeguarding U.S. agriculture and human health.
📍 United States
Most Americans associate bats with Halloween, but these nocturnal creatures are quietly contributing to the economic well-being of the United States in ways most people don’t realize. Bats perform essential services, from pollinating valuable crops like blueberries and agave to controlling insect populations that threaten both agricultural yields and public health. Their guano, a byproduct of their feeding habits, is a valuable fertilizer, and their voracious appetite for bugs helps to keep populations of disease-carrying insects, like mosquitoes, under control. The impact of their disappearance would ripple through the agricultural economy, affecting farmers, rural communities, and even financial markets.
The biggest threat to bat populations is white-nose syndrome, a devastating fungal disease that has decimated bat colonies across North America. First discovered in New York in 2006, the fungus, *Pseudogymnoascus destructans*, has spread to nearly every state, killing up to 99% of infected bats. The disease forces bats to remain in torpor for extended periods, exhausting their energy reserves and ultimately leading to death. This decline in bat populations is directly linked to increased insect populations, which in turn cause significant damage to crops, particularly cornfields.
Consider the cucumber beetle, a major threat to U.S. corn production. Rootworm, a larval form of the cucumber beetle, destroys massive amounts of corn each year, costing farmers billions of dollars in pesticide applications. A colony of big brown bats can consume hundreds of thousands of cucumber beetles annually, effectively preventing the production of millions of rootworm larvae. The loss of bats means increased crop damage and substantial economic losses for American farmers, highlighting the critical role these often-misunderstood animals play in maintaining the stability of the nation’s agricultural economy.
