Bats Get a Bad Rap. Here’s the Honest Science on Why Your Yard Needs Them.

Bats have an image problem that has nothing to do with what they actually do in your backyard. As a biologist, I have to correct a popular claim right up front: you have probably heard that a single bat can eat 1,000 mosquitoes in an hour. That statistic traces back to a 1960s lab study where a bat was placed in an enclosed room with no other food source, and it has been repeated so often that it is now treated as fact.
In the real world, with real food options available, the number is far lower. That said, the honest version of the story is still genuinely impressive, and it does not need exaggeration to make the case for why bats belong in your yard.
Between 77 and 84 percent of little brown bats in the northern United States and Canada eat mosquitoes as part of a varied insect diet.
What Bats Actually Do For Your Yard
A single bat can still consume hundreds of insects in a night, including moths, beetles, and agricultural pests along with the mosquitoes. Bats also provide pollination services for certain native plants and disperse seeds in ways that support forest regeneration, particularly in the western and southwestern United States.
A properly mounted bat box gives bats a safe daytime roosting site close to a reliable food source.
Bats are also in serious trouble. White-nose syndrome has devastated bat populations across North America, and habitat loss has made safe roosting sites increasingly hard to find. A bat box in your yard is not just a nice addition. It is a genuine conservation action for a group of mammals that badly needs the help.
How to Responsibly Attract Bats to Your Yard
Attracting bats does not require much. A properly mounted bat box, positioned in a sunny spot at least twelve feet off the ground, gives bats a safe daytime roosting site if your yard already has native plants supporting a healthy insect population.
- Mount the box at least twelve feet off the ground in a sunny location
- Skip pesticides entirely — a bat box near treated plants offers no food source
- Plant native flowering species nearby to support the insect population bats feed on
- Be patient — bat boxes can take a full season or two to get discovered
The honest science on bats is compelling enough on its own. You do not need the inflated mosquito numbers to justify giving them a home.
