The Department of Health, which runs Fulgencio Cervantes, will be spraying against mosquitoes because they have detected the clouds of these insects by rising temperatures.
Two teams of two people each, with smoke cannons distributed insecticide, will be responsible for this task.
The spraying, which begin at 7:00 pm and last until 9:00 am, are made by the two sides of the river on their way through the city of Murcia.
The insecticide is harmless to people.
The fumigation work will last one hour and hour and a half.
The operation is repeated throughout the week except Wednesday, June 9, depending on the number of mosquitoes that are detected.
