You might not know this, but bats are more closely related to humans than they are to rodents. And like humans, bats like a safe, suitable place in which to roost, especially in the spring when they are getting ready to have pups. As natural habitats disappear, finding adequate space to roost is becoming a challenge for Canada’s endangered bat species.
There are things we can all do to support declining bat populations by ensuring they can find and enjoy a safe haven, even in urban environments. Many myths and misinformation exist about bats, a species that plays a vital role for humans by helping control insect populations. Read on and discover ways you can help Canada’s bats!

Win An Echo Meter 2 Bat Detector!
The Canadian Wildlife Federation Help The Bats initiative is inviting interested bat lovers to get involved in bat monitoring this summer for a chance to win an Echo Meter 2 Bat Detector. Anyone who has a bat box installed on their property is eligible for the contest.
There are over 1,300 bat species worldwide, 19 of which call Canada home. Our bats are incredibly important, not only to the environment but to the economy too. When the sun goes down, bats get to work eating the annoying pests in our backyards. They’re also extremely beneficial to the agricultural industry. In fact, bats save the agricultural industry in North America $3.7 billion every year.
Although we may not always see them, bats are hard at work all around the world each night – eating thousands of mosquitos and other insects, which helps all of us by providing millions of dollars’ worth in pest control. Bats are in trouble. A disease known as White-nosed syndrome has wiped out millions of bats in North America. Habitat loss, pesticide use and evictions from roost sites produce an added threat to already stressed populations.
Millions of bats have died in Canada over the past 10 years.
They may not recover without our help.

As a means to promote the protection and recovery of the Little Brown Bat, CWF is engaging homeowners and humane wildlife control companies for better management and coexistence with bats by:
As spring sets in, bats are waking up from hibernation or migrating back from their southern winter homes.
Help the Bats is the Canadian Wildlife Federation’s response to ensure Canadian bat populations are protected.
Your gift will help fund CWF efforts to address the threat to the Little Brown Bat from white nose syndrome.
