What Kind of Bat is Hanging Outside My Door

Bats are often portrayed as spooky creatures associated with the supernatural and Halloween. However, these flying mammals have an important and fascinating role in our ecosystem. Bats hanging outside your door are a problem that many people in Colorado face, especially during the warmer months.

So why are they hanging outside your door? Bats often roost (rest or sleep) in dark, secluded places during the day. This can include caves, trees, and even buildings like houses or barns. Unfortunately for us humans, this sometimes means they may choose to roost in the eaves or crevices of our homes. This is because these areas provide shelter and protection from predators.

In Colorado, there are over 18 species of bats that call this state home. These include the little brown bat, big brown bat, hoary bat, and silver-haired bat, among others. Most of these bats are insectivores, meaning they mainly eat insects like mosquitoes and moths. This makes them valuable allies in controlling pest populations.

What is a Bat?

First of all, what is a bat? Bats are the second largest group of mammals, with over 1,400 species worldwide. They are the only mammal capable of true flight, thanks to their specialized wing structure made up of thin skin stretched over elongated finger bones. Here in Colorado, we have 18 different species of bats that call our state home.

Bats play an important role in controlling insect populations. In fact, one little brown bat can eat up to 1,000 insects in just one hour! This makes them valuable allies for farmers and gardeners who want to reduce the use of pesticides.
But despite their helpful nature, bats often get a bad rap. Many people associate them with spooky, Halloween imagery or think they are pests that spread diseases. However, most bats do not pose any threat to humans. In fact, less than 1% of bats actually carry rabies and will only bite if provoked.

Contrary to popular belief, bats are not blind. They have small eyes and rely on echolocation to navigate and hunt for food in the dark. Echolocation is a process where they emit high-frequency sounds that bounce off objects and return as echoes, allowing them to create a mental map of their surroundings.

Bats: Masters of Adaptation and Ecosystem Balance

Bats also have unique adaptations that make them well-suited for their environment. For example, their wings are thin membranes stretched over elongated finger bones. It is allowing them to fly with precision and maneuverability.

Bats are often associated with Halloween during this time of year due to their mysterious appearance and nocturnal behavior. But let’s remember that these creatures are an important part of our ecosystem year-round.

So next time you see a bat flying around at night, remember that they’re not spooky or scary – just another fascinating creature coexisting with us on this planet. And if you’re lucky enough to catch a glimpse, take a moment to appreciate their unique abilities and their essential role in our world.
