Thousands of abandoned and neglected swimming pools are turning into breeding grounds for mosquitoes.
"One of these pools that goes south or turns green and has mosquitoes in it can literally impact an entire neighborhood, where all the surrounding homes are at risk and in jeopardy," Michael Breen with Green Bullet said.
Breen contracts with sixteen area cities including West Palm Beach and Wellington to clean up dangerous, green pools.
"They nicknamed me the algae assassin...I enjoy assassinating algae," Breen said.
Breen uses a chemical product he developed called the Green Bullet.
He says he is especially passionate about his work because years ago when his pool turned green after a hurricane his entire family got sick.
"When it turned green the entire family suffered from dengue fever. We were all sick for over a month and there is nothing you can do about it," Breen said.
Breen says he sees some of the worst issues at foreclosed homes.
"What was once a personal asset has now become a community liability," Breen said.
Experts say not only are unkempt pools breeding grounds for mosquitoes, but they also pose a major drowning risk because if a child falls in you can't see them at the bottom of the pool.
