Barnett said she and her husband killed 30 copperheads on their property last week alone. She said another snake was found Tuesday.
"I nearly stepped on it and then I just ran and waited for my husband to come outside and kill them," Barnett told KXAS-TV.
She said she is worried about her pets and young grandchildren, especially her 4-year-old grandson.
"He knows. He goes, 'Oh Momo's got a bunch of snakes.' And I said, 'Yes, Momo has a lot of snakes,'" she told KDFW-TV.
Randall Kennedy of pest removal company Fort Worth Wildlife visited the property Wednesday and determined it was a perfect habitat for copperheads.
"Any thicket is a real good place for them," he said.
"Once they start taking over, they'll take over," Kennedy said. "There can be quite a few of them."
