West Monroe, N.Y. - Oswego County officials will try again for a fourth night tonight to reduce the mosquito population.
Aerial spraying to eliminate the insects has been delayed since Friday due to weather conditions. Spraying is needed after mosquitoes around Toad Harbor Swamp keep testing positive for recently Eastern equine encephalitis.
A horse infected with Triple E in West Monroe died last week.
Officials say they will try and spray tonight at 6:00 p.m. Spraying is expected to last 3 to 4 hours.
