Despite large-scale mortality, Little Brown Bats are persisting in Canada and even reproducing. @Karen Vanderwolf<\/figcaption><\/figure>\nCanada\u2019s bats practice a unique reproductive technique called delayed fertilization. Females<\/a> store sperm from last fall\u2019s mating season and fertilize in the spring. This gives females a head start on developing and birthing their pup, which they do in places called maternity roosts.<\/p>\nBats are very loyal to their roosts. Females will return to the same maternity roost each spring and congregate together to optimize heat; they need temperatures between 30-40o<\/sup>C and just the right level of humidity.<\/p>\nThe Perfect Roost<\/h3>\n

An ideal roost for bats could be a natural spot, such as a hollow tree or rock crevice, or a human-made structure, such as a soffit, barn, garage or attic.<\/p>\n
Bats can also roost in dead trees that have been left standing, provided there\u2019s no risk of the tree falling and causing damage or harm.<\/p>\n
You can provide moms-to-be with a home by building your own two-chambered bat house using our \u00a0DIY plans<\/a>. It can take a little time for bats to get used to a bat house, so don\u2019t be disappointed if your house isn\u2019t used right away. It\u2019s best to install your bat house in spring to give bats time to warm up to it.<\/p>\nWe have tips for how and where to install your roost<\/a> to give it the best chance of being occupied.<\/p>\nOccupancy Full<\/h3>\n![\"bat](\"https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2019\/12\/bat-in-wall-1100x640.jpg\")
\u00a9 James Pag\u00e9<\/figcaption><\/figure>\nIf you have bats in your attic or other structure, it\u2019s best to leave them be. If they\u2019re causing a problem or health concern, don\u2019t evict them between early and late summer \u2013 females in late pregnancy won\u2019t be able to find another suitable site before giving birth in mid-summer.<\/p>\n
Once born, pups can\u2019t fly until late summer. They sometimes venture out while hanging onto their mother, but at other times they are left in the roost. An eviction from an attic or other structure allows bats to leave, but the mothers can\u2019t get back in. Pups inside either die or try to find another way out, which may lead them into other areas of the home.<\/p>\n
If you have an occupied roost, lucky you. Here are some direct benefits:<\/p>\n
\n- Provides an entertaining activity at dusk (it\u2019s a hit with the kids)<\/li>\n
- Keeps insect-eating bats on your property<\/li>\n
- Contributes to conservation science<\/li>\n<\/ul>\n
The Canadian Wildlife Federation is researching occupied roost sites and working to determine the best bat house designs. You can contribute to our research by monitoring your roost and sharing your observations on iNaturalist.ca or the iNaturalist app. We have a step by step guide for how to easily monitor your bat house and enter your observations<\/a>.<\/p>\nKeep an eye on the horizon at dusk and you might just catch a glimpse of an incredible creature in your own backyard.<\/p>\n
