Homeowner Hears 'Squeaking' in Their Attic Which Turns Out to Be 1,000 Bats

A homeowner was shocked after the "squeaking" coming from their attic turned out to be a colony of more than 1,000 bats.

Chris Garegnani shared a clip to his TikTok page, chris_g72718, as he filmed the roof space teeming with the nocturnal creatures.

The window appeared to be covered in a mass of mammals, as Garegnani captioned the clip: "That's well over 1,000 bats."

The footage, posted earlier this March, amassed more than 2.5 million views, and can be seen here, as people weighed in on the striking sight in the comments.

I have mastered pettiness asked, referencing the popular films: "Who's playing Jumanji?"

This is Me joked: "That's not an attic. That's a belfry!!!"

Mike Spiziri pointed out: "Definitely don't have a mosquito problem."

Eragon The Dragon thought: "Truthfully I'd rather have bats than spiders..."

Rocks and Rarities quipped: "At least your house is federally protected now lol."

While Miguel9o_ added: "Time to file a claim with insurance for house fire."

Garegnani, who confirms he works in "wildlife relocation," said in the comments: "No bats were harmed."

In response to the interest the original clip received, Garegnani revealed exactly how the bats had managed to get inside the house.

"For those asking about an entry point for the bats," he captioned a follow-up video, shared last week.

He pans up the outside of the building, and zooms in on a small gap, acknowledging: "It may be hard to see it, see all that darkness right there, that's where these bad boys been coming in and out of. Very overlooked area of a house."

He seemed to share another clip focusing on the bat's entry point, as he films "check valves."

The clip, also captioned "locating the entry point," showed him up close and personal with the tiny gaps.

While it wasn't confirmed where the house is, a Massachusetts government website shared information about the mammals, and how best to co-exist with them.

It pointed out: "It's important to note that bats can squeeze through a hole as small as 1/2 inch...

"The most common entrance ways for bats entering a home include an unscreened attic vent, a crack or separation where the chimney meets the house, a hole or crack under a rotted eave, rotted window sills or loose-sitting screens, chimney flues, pet doors, an open cellar hatch (bulkhead), where pipes or wiring meet the house, or gaps in loose or warped siding."

In the background of the video Garegnani said: "It's very small, but customer has confirmed bats have been flying in and out of this area right here.

"Definitely wouldn't notice it on first glance."

In another comment he explained: "Used a check valve to let them fly out, but not get back in. This shows them flying around, trying to find a way back in the house."

And in a third part, he seemingly shared the conclusion to the bat saga, as he filmed hoards of bats flying outside the house.

"The morning after, fly free my winged brethren," the on-screen text said, suggesting the bats had been evicted from the attic.

Along with the hashtag "flyfree," he wrote: "Sorry I couldn't get a video of them flying out. Need to invest in a trail cam."

The Mass.gov website claimed most bats found in houses were likely little brown bats or big brown bats.

It said: "In the summer, with hot, humid weather, some homeowners may discover bats residing in their home. Attics are the most common area of a house in which bats are most likely to roost and gather in a colony to raise their young."

Newsweek reached out to Garegnani for comment.
