SAN ANTONIO -- They're back in South Texas after flying south for the winter. For generations millions of Mexican free-tailed bats have found a home just north of San Antonio in the Bracken Cave.
However, one colony of the bats decided to make a home inside an apartment complex not far from Ingram Park Mall and it's frustrating tenants.
Frank Hall lives in the third floor of the Hills Stone Creek apartment complex. He loves his apartment but is not a fan of his "little neighbors."
"My bed is like right there. I sleep two feet from them," said Hall. "The sound at night -- you hear the chirping, like a lot of mice."
Dozens and dozens of Mexican free-tailed bats live in his walls.
"I noticed they were coming out of the side of the wood," he said pointing to the side of his bedroom window.
Just a few minutes into our interview, as the sun began to go down, KENS 5 cameras caught them coming out just as Hall said.
"You are not allowed to kill them. You have to be really careful when removing them," said Jeremiah Crampton with A All Animal Control.
Their breeding season, which will soon start, is also protected. Crampton said there's not much people can do, other than safely remove them.
"We install bat doors and netting where they can leave, but they can get back in," Crampton said.
Neighbors said it's pretty neat to see them come out, but when they have one close encounter too many, it's too much.
"I turn around and I saw a black thing coming toward me," Hall said. "I didn’t know what it was, I just felt it. It landed on my back, I grabbed it, and I tossed it to the side."
Hall is getting ready to move. He's had enough of the critters.
"You hear them all night long and it's just creepy," Hall said.
The apartment complex manager said they're aware of the bat problem and they try to remove them as safely as possible without disturbing their breeding season.
