Due to the colder weather, roads along the MIT campus will not be sprayed with pesticide tomorrow (September 7) to eradicate mosquitoes that might carry the West Nile Virus.
In temperatures below 60 degrees Fahrenheit, mosquitoes become less active and the insecticide is less effective. Colder temperatures are expected in Cambridge at night all week.
The second round of spraying was scheduled last week after a dead crow infected with the West Nile Virus was found in Cambridge. The initial spraying on campus took place on August 17.
