The people of Arizona are a hardy breed. They have to be to live in the desert surrounded by scorpions, lizards, and snakes. Few people realize just how many bats live in Arizona though. And yes, even Phoenix is filled with them.
Phoenix is actually home to a colony of Mexican free-tail bats that is over 10,000 strong. That’s a very large colony. They live in a flood control tunnel in Arcadia during the summer months to give birth and then most leave in August or September to migrate back to Mexico. Arizona Game and Fish has been monitoring the colony since the 1990’s. There are signs posted educating area residents about the bats since they are located in a popular hiking area.
So, if there is a very large colony of bats living in a densely populated city like Phoenix, imagine how many there are in more rural areas like Happy Jack, Arizona for example.

Texas is well known for its extremely large bat colonies. This is due mainly to the species of bats that take up residence there. Mexican free-tails are well known for their large colony sizes. And Arizona is chalk full of them as well.
A couple years ago, there was even a public service announcement about an extreme heatwave driving the bats in people’s homes and businesses where it was cooler. Bats inside an occupied living space is a really bad thing for so many reasons. Rabies, histoplasmosis, and property damage being the big three items.
Don’t Let Bats Hang Around Your Home
Bats are great for our ecosystem. We highly encourage you to make sure they stay outside though. Living with a bat infestation inside your home of building is just a recipe for disaster. And bats don’t just go away once they’ve established a roost. Think of them like mice. If you have mice in your house, you address it appropriately as you should. The big difference is that it’s a lot harder to get bats out of your home once they are nice and comfortable there.

Several years there were wild cats in my central Phoenix neighborhood and would visit my backyard at dusk. I haven't seen them in many years. Where did they go and why? Thx!

There are different possibilities for why bats disappear. Sometimes they have to change where they roost due to being excluded from a building, deforestation, or possibly weather. Or sometimes disease will go through a colony (like white-nose syndrome).

In what region of Arizona can Hoary Bats be found?

Hi, Hoary bats like areas that are undisturbed by people. So they are not as likely to be the bats roosting in your attic. In Arizona, they are found in National Parks and in other less populated areas.
