Preparations for Halloween trick-or-treating in Jefferson Parish include spraying for mosquitos.
Both aerial spraying and ground level spraying were conducted in the parish Tuesday evening.
Steve Pavlovich, an entomologist with Mosquito Control Services, the company under contract with the parish to do the spraying, says there's been an increase in the pest mosquito population.
"We were hitting the mosquitos both with the trucks and the aircraft in anticipation of the upcoming trick-or-treating events," Pavlovich said.
He says salt marsh and woodland mosquitos are the more aggressive biters.
