• Only mammals capable of true flight

• Play crucial roles in insect control and pollination

Habitat and Behavior:

• Found in various habitats including forests, caves, and urban areas

• Most are nocturnal, emerging at dusk to feed

• Many species hibernate during winter, while others migrate

• Use echolocation to navigate and locate prey

Life Cycle:

• Mating typically occurs in fall, with delayed fertilization until spring

• Pups can fly within 3-6 weeks

Diet:

• Primarily insectivorous, consuming mosquitoes, moths, and beetles

• Some species also eat fruit or nectar

• Can consume up to half their body weight in insects nightly

Unique Characteristics:

• Highly developed echolocation abilities

• Can live up to 30 years in the wild

• Some species can enter torpor to conserve energy

Human Interactions:

Common Occurrences:

• Roosting in attics, barns, or other structures

• Occasional sightings during dusk flights

Uncommon Occurrences:

• Bats entering living spaces

• Accumulation of guano (bat droppings) in attics or walls

Resolution Methods:

DIY Solutions:

• Install bat houses to provide alternative roosting sites

• Seal entry points to homes after ensuring all bats have left

• Use bright lights in attics temporarily to discourage roosting

Professional Wildlife Control:

• Humane exclusion using one-way devices

• Thorough inspection to identify all potential entry points

• Proper cleanup and decontamination of affected areas

Advanced Management:

For ongoing bat issues, consider a multi-faceted approach. Timing is crucial - exclusions should only be performed when young are not present (typically late August through early May in NC). Install proper ventilation in attics to reduce humidity, making them less attractive to bats. Use ultrasonic devices designed to repel bats, but be aware of their limited effectiveness. Regularly inspect your property for potential entry points, paying special attention to areas around chimneys, vents, and where walls meet the roof.

Always wear protective gear when cleaning up bat guano, as it can harbor harmful fungi. If a bat is found inside your living space, do not attempt to handle it yourself - contact a professional immediately, as bats can potentially carry rabies.

Remember, it's illegal to harm or kill bats in North Carolina. Always use humane, exclusion-based methods and consult with a licensed wildlife professional for large-scale bat issues. By understanding and respecting these fascinating creatures, we can coexist more harmoniously with our important nocturnal neighbors.
