Whitefly Invasion

demo The Whitefly arrived in Florida in 2009. Today it is found from the Florida Keys to the Palm Beaches. Areas infested leave a "honeydew-like" like film on pools that rapidly depletes chlorine. A favorite host to the white fly is the coconut palm, often found near pools. If you are experiencing rapid chlorine depletion that cannot be explained by any other means, contact you pool professional.
