Bats in Halloween Folklore and in the History of Halloween
Bats, Bonfires and the Celtics
What images come to mind when you think of Halloween?
Pumpkins, witches, and goblins, black cats, and—of course—bats!
Bats are one of the spookiest and most enduring images of Halloween. But how did the image of this harmless and beneficial flier become a feared harbinger of darkness and evil?
The History of Halloween Bats: The black, winged shapes flying through the dusky night sky are eternally linked to Halloween. It may have started long ago, when the ancient Celtics lit large bonfires as darkness approached to ward off the evil spirits of the night. According to the legends, the Celtics believed the ghosts of their ancestors returned to earth once each year on the night of October 31st when the spirits of the dead could cross over into the world of the living. These unruly spirits roamed the lands in search of mischief and mayhem. As protection from the ghosts, the Celtics held an annual celebration on this night, known as Samhain (pronounced as "sah-win"), which also marked the end of the harvest season. The superstitious Celtics, dressed in costumes made from animal skins and hides, gathered around large bonfires to burn sacrificial offerings of crops and animals to appease the demons returning from the the Other World.
As the bonfires burned into the night, the glow and warmth of the fire attracted mosquitos and other flying insects into the surrounding area. In turn, the flying insects attracted hungry bats, swooping and darting in and out of the dusky light from the fire in search of their prey. The dark, shadowy and fast moving shapes flying through the semi-darkness may have appeared to the Celtics as the embodied spirits of the returning the dead, and the symbol of the bat became forever embedded in the roots of Halloween lore.
Halloween Bats: Friend or Fiend?
Creepy Demons of the Night...
For centuries, tales and rumors of blooding-sucking bats spread throughout Europe. The evil images of a winged demon stalked the night to prey on the blood of unsuspecting victims while they slept fit perfectly into the dark lore of Halloween.
The discovery of the vampire bat in South America by the Spanish in the 17th century strengthened the stories of blood-hungry demons in search of a meal. Many believed that the unfortunate victims transformed mysteriously into human vampires that sought the blood of more victims. As stories of human vampires spread, it was widely believed that the vampire could transform into the shape of the bat -- creating another tie between the evil winged creatures of the night with the symbols of Halloween.
... Or Beneficial Nocturnal Hunters?
Fortunately, these beneficial creatures are not the evil demons of the dark -- unless you're a moth or mosquito. Bats have voracious appetites, and they can eat over 1,000 flying insects in a single night. They hunt their prey using echolocation, a type of radar that enables the bat to find and zero in on flying insects in total darkness.
Contrary to popular myths, they are not blind. In fact, most of the bat species have excellent eye sight. Some species, such as the Flying Fox, eat a diet of fruit and help disperse the seeds to rejuvenate the forests where they live. Others are important plant pollinators, spreading pollen from plant to plant as they search through the flowers for nectar.
Sadly, many of the world's bat species are in serious decline, threatened by the loss of habitat for nesting and for roosting sites. You can help by hanging a bat house to encourage these interesting, harmless and beneficial predators to take up residence in your yard.
“Not every winged creature is considered a bird or a bat. Some wings are made of magic."— Raani York – 2013

Give a Bat a Home
Inviting Bats Into Your Yard
Give these special animals a place to live by hanging a bat house. Little brown bats are welcomed visitors to our yard, circling around the tree tops at dusk and swooping down in search of a meal. I even made a wooden bat home for them so they'd visit more often. If you want to build your own box, I've created a thorough set of step-by-step bat-home instructions. Preying on insects, a bat is capable of catching and eating hundreds of mosquitoes and other flying pests every evening.
Bat houses are available in different sizes through various online retailers, or you can build one yourself. Just make sure that the roosting box is built to the dimensions and meet the basic roosting requirements of the species found in your local area.
Where you hang a bat house is also important for attracting these finicky residents. Face the box towards an open area, preferably with a southern exposure to maximize the amount of warmth from the sun, and mount it at least 10' up from the ground. The higher, the better.
