City crews have begun monitoring areas with standing water to determine if larviciding for mosquitoes is necessary, the City of Edinburg announced Friday.

Actual extermination of mosquito larvae, if necessary, will not begin until Tuesday at the earliest, according to Edinburg's Department of Solid Waste.

If by Tuesday morning July 6, 2010 the water has not drained then crews will begin actively larviciding, said Solid Waste Director Ramiro Gomez.

Crews will continue to monitor any standing water to determine if adulticiding is needed through out the city.
