DYKER HEIGHTS, Brooklyn — Mary Jane Koller has more than a bee in her bonnet.

She's got two large hornets nests right outside her front door on 76th street in Dyker Heights. One is the size of a basketball. The other the size of a grapefruit.

"We thought it was bees, then wasps and now we are know they are hornets," Mary Jane Koller told PIX11. "If you get stung by a hornet, you need to get professional help."

The hornets' nests have been up in the branches of the city-owned tree on the public sidewalk for at least the last two weeks.

Everyone on this block is buzzing. Neighbors say they are frightened, particularly since there is a block party this coming Saturday with lots of children and food to attract the hornets.

"I am worried about my children and grandchildren," Eileen Bille, neighbor, said.

Ava Angelina, the owner of a Pomeranian named Shayna, is worried about walking her. "It's scary," Ava said.

Koller has called animal control, 311, City Councilmember Vincent Gentile's office and finally the NYC Parks Department. But a city parks department employee showed up and said they don't have the proper equipment to remove the hornets nest.

PIX11 called Councilmember Gentile's office. Chief of Staff John Mancuso said a beekeeper under contract with the NYPD is expected at dusk to remove the hornets nests.

"The media coverage really helped get the NYPD beekeeper heading this way," Mancuso said.

The hornets have been removed by a beekeeper.
