Installing a bat house is a great way to attract bats to your property! Here are some helpful tips and tricks for attracting bats to their new homes.
There are many reasons for wanting bats in your backyard. Whether its to benefit from their pollination services, pest control, or you just simply enjoy their nightly displays of aerial acrobatics, consider these three tips for attracting bats to your backyard.
Leave Dead Trees
For many species of bats, dead trees provide the crme de la crme of roosting locations. The narrow, rough space between the bark and the wood provides the ideal space for a bat (or few) to squeeze in nice and tight. If a dead tree does not pose a safety concern, consider leaving it in your yard to provide protected refuge for bats and the insects they eat.
Dead tree not an option? Give the bats the next best thing a bat house to mimic the space and habitat that a dead tree would normally provide.
Build or Buy a Bat House
Building your own bat house is a great way to get involved in bat conservation. Bat Conservation International (BCI) has designs for three different types of roosts freely available on our website: single chamber, four-chamber, and rocket boxes.
Make sure to check out our website for additional tips and tricks for building your own bat house.
Once you have your bat house, check out BCIs installation tips.
BCI has learned many lessons during out 10-year Bat House Research Project. But remember, though we have developed best practices based on years of experimentation, please dont feel you cant have a bat house if your conditions are not exactly like the ones we suggest.
Here are some tips to get you started….
1. Where should I place my bat house?
Bats prefer roosts mounted on buildings or other large wooden or concrete structures to those mounted on poles or on trees (not recommended). But pole mounts work well in climates that are moderate to hot, without extreme variance between day and night temperatures.
Bat houses should receive at least six hours of daily sun exposure.
2. How many should I install?
If more than one roost is desired, begin by testing a few in different places. You can mount them next to each other on a building, painted or stained different colors, or on poles back-to-back, a light one facing north and a darker one south. Bats are more likely to move into roosts grouped three or more together.
3. How high should the house be?
Best siting is 20-30 from the nearest trees and at least 10 (from the bottom of the roost)12-20 is betterabove ground (or above the tallest vegetation beneath the bat house). Locations nearest an areas largest water sources are the most successfulpreferably mile or less.
Keep Fluffy Indoors
We all love our furry feline friends, but cat attacks are one of the most common causes of bat casualties. Keep your cat indoors at night, especially during the summer months when the mothers are taking care of their young. If you are unable to keep your cat inside all night, bring it in about a half hour before sunset until an hour after sunset this is when bats are most active. If your cat has found a bat, s/he may have learned where the roost is and will return which places the entire colony at risk.
