Rollins College Biology Professor Explains Why Bats Benefit Gardens

Bats circling a garden at night might initially cause alarm for homeowners, but pest control and ecology experts agree that their presence is actually a major benefit to local ecosystems. According to an article from The Spruce, bats serve as highly efficient, natural pest control. A single bat can consume thousands of destructive insects—including mosquitoes, beetles, and moths—in just one night. Additionally, their droppings, known as guano, act as an excellent organic fertilizer when properly composted.

While a high concentration of bats might indicate a nearby roost, experts encourage residents to appreciate these nocturnal visitors rather than fear them. Fokidis highlights the peace of mind they should bring to gardeners.“If bats are looping quietly over your yard at twilight, take it as proof that something is going right,” Fokidis says. He views their nightly routines as a hands-off victory for homeowners, noting, “They are doing serious ecological stuff while you are reaching for a drink, and that is a pretty good deal. Pull out your lawn chair and watch them work.”

Fokidis also emphasizes that bats are essential pollinators for night-blooming plants like cacti and agaves in tropical and desert climates, explaining that these species “evolved with bats in mind, not bees, hummingbirds, or butterflies.” He notes their absence would cause these plant populations to collapse, adding with a touch of humor, “Perhaps you've never grown agave, but I bet you like the tequila in your margarita.” Ultimately, the article recommends welcoming these creatures by planting native flora and properly installing detached bat boxes.
