Could Bats Help Control the Spotted Lanternfly Invasion?

The spotted lanternfly ( Lycorma delicatula) has become one of the most notorious invasive species threatening forests, agriculture, and ecosystems across the eastern United States. As this insect rapidly expands its range, land managers and researchers are urgently seeking natural solutions to control its spread. 

A new study published in Forests (MDPI, 2023) offers a hopeful — and surprising — potential ally in the fight: bats. 

The Spotted Lanternfly Problem  

Originally from Asia, the spotted lanternfly was first detected in Pennsylvania in 2014 and has since spread across the Northeast and Mid-Atlantic. Its preferred host, the invasive tree of heaven ( Ailanthus altissima ), is common along roadsides, forest edges, and disturbed habitats — making containment especially difficult. 

These insects cause extensive damage by feeding on sap from trees and plants, weakening them and leaving behind a sticky residue that promotes mold growth. The economic impacts are significant, affecting vineyards, orchards, timber, and even tourism. 

Bats as Natural Pest Control  

Recent research reviewed global studies on forest-dwelling bats and highlighted emerging evidence that some native bat species may be consuming spotted lanternflies. 

This is promising news for several reasons: 

• Bats are voracious insect predators, capable of eating thousands of insects in a single night. 
• Utilizing native species for pest control reduces reliance on pesticides and promotes ecosystem balance. 
• Bats often forage along forest edges, roadsides, and near water — the same areas where spotted lanternflies tend to congregate. 

While more targeted research is needed to fully understand the extent of bat predation on lanternflies, early findings suggest that enhancing bat habitat could be part of an integrated pest management strategy. 

Supporting Bats, Supporting Forest Health  

At Volant EcoServices, we specialize in bat research and habitat assessments. Protecting and enhancing bat populations isn’t just good for biodiversity — it may also provide tangible benefits in controlling invasive pests like the spotted lanternfly. 

We assist clients with: 

• Acoustic monitoring to document bat activity 
• Roost surveys and habitat evaluations 
• Conservation planning that promotes healthy bat populations 

As this research evolves, we’re optimistic about the role native wildlife can play in restoring balance to our forests.
