Mosquito counts this year have been so low that county crews only sprayed one night during the entire month of July, said Jim Diggs, Gloucester’s mosquito control director. And the paucity of mosquitoes continued into August, with crews spaying just three nights during the first 16 days of this month.
"It’s a great year for us and a bad year for mosquitoes," Diggs said. Crews have been out constantly in the control districts to conduct mosquito counts and inspect traps which have been in use. But most of the time there are not enough mosquitoes to warrant spraying, he said, or the weather—rain and brisk winds—might not allow for spraying from specially-mounted trucks.
In fact, Diggs said crews didn’t begin spraying until early June this year, which is later than usual.
Some of the rainfall this year was heavy, which helped wash away some of the mosquitoes, Diggs said. Also, larvicide placed in ditches has helped cut the mosquito numbers.
