There’s no set formula for number of bat houses to acres. About 20% of BatBnB customers actually purchase two or more BatBnBs for their property because having more than one BatBnB actually increases occupation rates. The reason is fascinating. Without bat houses around, bats look to live in the crevice formed between the peeling bark on a dying tree, which is actually the environment that a BatBnB biomimics. Now if you are a mother bat with a pup and your preferred real estate is peeling bark, your number one concern is what to do if that bark peels off, leaving you and your pup exposed to predators. That’s why bats are actually smart enough to scout a location for multiple real estate options before they decide to settle there in the Spring. So therefore, with multiple BatBnBs, you’re more likely to attract more bats faster.
