Best Way to Set Up a Bat House
Bats are important to the ecosystem. Here'due south how to fix a bat house on your property.
Every bit symbols of Halloween and all things spooky, bats take a bad reputation. In films, they're always present in graveyards and haunted mansions. In folktales, they're manifestations of vampires, out to suck your blood. And in everyday life, they're ofttimes seen as unsafe pests. But in recent years, conservationists have have devoted more resources to educating the public about the benefits of bats and how they play a crucial role in the environment.
As a result, some people are adding bat houses to their properties in hope of alluring bats and offering them a identify to roost and raise their young.
"Bat houses are definitely becoming more popular," Doug Hitchcox, staff naturalist for the Maine Audubon, an organisation that sells bat houses at its nature centers throughout the land and has hosted several public presentations on bat conservation in recent years.
Bat houses are essentially wooden boxes filled with narrow chambers where bats tin can rest, conserve free energy and stay warm during the 24-hour interval. At night, they emerge to hunt, with the bulk of the world's bats feeding on vast quantities of insects. Other bat species swallow fruit, pollinating plants and distributing seeds in the process.
Bat houses are as well a place where bats can requite nascence and heighten their pups in the spring and early summertime. The shelter serves as protection, and as a place where bats can gather and form a cohesive colony.
Where to put a bat house
In the United States, ane of the top authorities about bat houses is Bat Conservation International, an organization devoted to the protection of the world's i,300-plus species of bats. This organization conducted a x-yr Bat House Research Project, enlisting volunteers to research hundreds of bat houses and other artificial roosts.
From this inquiry, BCI learned that the all-time location for a bat house is on the side of a building, believe it or non. People are oft worried this will encourage bats to invade the building. And to that concern, BCI states on their website that "if bats were attracted to your attic or wall spaces and could get into them, they probably would already exist living there."
The best style to keep bats out of your habitation is by keeping the exterior of your house in good repair. Bats can enter spaces that are every bit minor equally one-half inch in diameter.
If you are successful in having bats move into your bat house, expect plenty of droppings — too known as guano — to fall from the bat house and accumulate underneath. For that reason, you'll want to put the bat firm in a place where you lot don't mind there being a bit of a mess beneath. Perchance a shed, outbuilding or barn. And for whatever reason, BCI found that bats prefer bat houses that are mounted on buildings with wood, brick or stone siding — but not metal siding.
Bat houses can also be mounted on poles. You could even fasten two bat houses together, 1 on each side of the pole.
Whatsoever you lot make up one's mind, make sure the bat business firm is located in an area with enough of sun for estrus. Ideally, they should be exposed to sunlight for half-dozen to 8 hours daily, so facing them to the south is a good idea. At a minimum, they should be placed ten feet off the basis, though 12 to 20 anxiety is ideal. And they should be located at least xx feet abroad from the nearest tree branches or other places where flying predators can perch.
"A lot of people attempt to put [bat houses] in trees, and that can be problematic," Fran Hutchins, Bat Conservation International'due south Director of Bracken Cave Preserve in Texas. "It makes them easy access to predators such as rat snakes and owls."
Copse also tend to be too shady.
How to attract bats to a bat house
There's no scent or detail you lot can place in or around your bat houses to concenter occupants, co-ordinate to BCI. When bats are looking for a overnice domicile, they consider three things: design, temperature and location.
Starting with design — non all bat houses are created equally. For this reason, Bat Conservation International provides detailed directions for the construction of three effective designs for bat houses. These designs were adult from BCI'southward Bat House Research Project (1993-2004), during which volunteers conducted enquiry on hundreds of bat houses and other artificial roosts.
BCI also provides links to premade bat houses and bat house kits that they consider to be adequate designs.
Many bat houses on the market place are too modest, Hutchins said, and the chambers inside them are ofttimes improperly spaced, assuasive for too much air menstruum and estrus loss.
"1 of the general rules is the bigger, the better," said Doug Hitchcox, staff naturalist for the Maine Audubon. "As colonial species, they like to be together, especially when raising their pups. They want as many bats in that area equally possible."
"You lot want them to be large enough to concur enough bats to stay warm," Hutchins said.
"The hotter the roost, the less energy they have to spend warming themselves."
In cold climates, bat houses will oftentimes be painted black (using outdoor, non-toxic, h2o-based latex paint) and then they absorb more heat during the day.
And last of all — location. BCI found that bat houses have a better take chances of attracting bats if they're located near large h2o sources. This is because near bats species feed on insects, many of which brood in water.
As well, bat houses tend to be more successful if they're away from bright lights. And if bat colonies are already established in nearby buildings or under bridges, bat houses are much more than likely to get occupied. In the aforementioned vein, if the bat house is located most a cave or mine that serves as a hibernacula, a place for bats to hide, they're more probable to become occupied.
Why bat houses matter
In the United states of america, one reason bat houses may exist gaining popularity is because of white-nose syndrome, a disease that was first discovered in the country in 2006 and has since decimated certain bat populations, killing millions of bats across N America. This wildlife disaster has heightened many people'due south awareness of the importance of bats, and has some people searching for means to help.
"Because of white-nose syndrome, a lot of the natural roosts are getting contaminated," said Hutchins. "[Providing] any additional habitat is helpful."
White-olfactory organ syndrome is acquired by a specific fungus that can be passed from bat-to-bat and picked up from the environment — chiefly caves where bats hide. In addition, different species of bats are losing habitat due the closure of old mines and deforestation, Hutchins said.
"One affair that's missing for bats are expressionless trees on the landscape," Hitchcox said. "It's those large, dead trees that perchance get hollowed out or accept loose bawl that maybe they'd desire to squeeze underneath, that's what nosotros're essentially replicating past putting up a bat house. It'south the same reason people put up birdhouses for swallows and bluebirds. So we're ever trying to convince people that what otherwise might await like an ugly tree is actually an of import piece of habitat."
Both tree roosting bats an cave-dwelling house bats with roost in bat houses, Hutchins said.
Be patient
Hitchcox said he often hears from people who put bat houses up, become discouraged when they don't see bats move in right abroad, then have them downwardly. His suggestion is to exist patient. From his experience, bats tin accept a while to locate and move into a new bat house.
"Bird houses tend to be filled upwards inside a calendar week of you lot putting them up, but bats — for whatever reason — they're but a little more picky," he said. "Information technology might have a couple of years before yous start noticing bats in it."
It's as well important to annotation that in colder climates, such as the Northeast, bats only use bat houses during the summertime to roost and heighten their young. In the winter, they motion out and either migrate or search for somewhere warmer to hide.
"So information technology's i of those situations where, built information technology, and they'll eventually come," Hutchins said.
