Don't mess with Nishanto Grillo.

This gutsy woman went toe-to-toe with an unwelcome visitor -- a massive black bear -- and sent the critter on its way with a series of highly annoyed shouts to leave her property.

This isn't the first time the Grillos have had a burly bear visit their home. A YouTube user named Nayana Grillo, who posted the video above on YouTube, has six other videos of a bear hanging out on the family's deck, much to Nishanto's chagrin.

Black bears have had increasingly more contact with humans, thanks to droughts depleting their food resources and getting a taste for human food from rummaging through garbage cans or humans feeding them. One black bear skipped a typical diet of berries and salmon and went straight for dessert after breaking into the Rocky Mountain Chocolate Factory in Estes Park, Colarado in August. Its treats of choice? English Toffee and giant chocolate cookies called "Cookie Bears."

“They’re looking at trying to consume 20,000 calories a day," Randy Hampton of the Colorado Parks and Wildlife Department told ABC News. "They will spend 20 of 24 hours a day looking for food."

Well consider Nishanto's back porch closed for business.
