Seminole, Fla. (Newsradio 970 WFLA)-Pinellas County Mosquito Control has confirmed positive results for St. Louis encephalitis in seven sentinel chickens. Four chickens were located at Walsingham Park in Seminole and three were in Cross Bayou in the unincorporated Seminole area. 

Last week, Pinellas County Mosquito Control confirmed two positive results for St. Louis encephalitis, one at Walsingham Park and one in Cross Bayou, bringing the total to five positive results at Walsingham Park and four positives in Cross Bayou in 2014. 

Sentinel chickens serve as an early warning system for some mosquito-borne diseases and can signal that skeeters carrying the disease are present in the area.

Pinellas Mosquito Control is treating known breeding areas by ground and by air and are responding to requests from residents. Additional fogging continues across the county.

Residents are urged to remove standing water from their property to eliminate mosquito breeding grounds.  Your are also being urged to use repellent while outside at dawn and dusk when the mosquitoes are most active.
