Dallas County officials say the next round of pesticide spraying is scheduled for Monday night, weather permitting.
The aerial spraying was prompted by an outbreak of West Nile virus that has left 10 people dead and more than 200 sick in Dallas County.
Storms interrupted aerial spraying last Thursday and Friday nights. Rainfall Saturday canceled the evening's spraying schedule.
The Environmental Protection Agency has said that the insecticide used in the spraying, Duet, poses no significant threat to humans or animals.
Symptoms of the West Nile virus include headache, high fever, neck stiffness, disorientation, coma, tremors, convulsions, muscle weakness and paralysis.
