Health Dept. Schedules Mosquito Spraying

Tuesday & Thursday July 17 & 19 at Dusk, Weather Permitting

PITTSBURGH - In response to mosquito samples repeatedly testing positive for West Nile virus in the East End, West End, Edgewood and Wilkinsburg, the Allegheny County Health Department will spray certain areas of these neighborhoods with mosquito pesticide on July 17 and 19 starting at dusk, roughly from 8 to 11 p.m.  In case of inclement weather, the spraying will be rescheduled for a later date.

The areas were selected for spraying based on having multiple positive samples over several weeks.  The neighborhoods include the lower part of Homewood South and Homewood Cemetery in Pittsburgh’s East End, Aberdeen Street in Edgewood, the Hunter Park area of Wilkinsburg on July 17, and Herschel Field, the City Tire Dump, and Zahniser Street in Pittsburgh’s West End on July 19.

The Department will be using a new mosquito pesticide called Zenivex which contains no piperonyl butoxide.  It kills adult mosquitoes, but is otherwise very safe and harmless to people and pets.  It will be released from a truck-mounted, ultra-low volume sprayer at a rate of just one to three ounces per acre.  Storm water catch basins in these neighborhoods have already been treated to stop the breeding of mosquitoes in standing water.

Health officials urge the public to protect themselves from mosquitoes by getting rid of standing water in yards and neighborhoods, using insect repellent on exposed skin and minimizing time spent outdoors during daylight hours – especially at dawn and dusk when mosquitoes are most active.

Thirty-one mosquito samples in the County have tested positive for West Nile since mid-May, but no human cases have been reported so far this year.
