Be on the lookout for pesticide spraying in your neighborhood this week.
West Nile Virus has been detected in three boroughs: Manhattan, Queens and Staten Island.
The city Health Department is dispatching trucks to do some preventative spraying.
They will be out from from 10 p.m. Thursday to 6 a.m. Friday in parts of southeastern Queens.
Several neighborhoods on Staten Island will also get sprayed.
The Health Department says the pesticides used pose a very low risk to humans at low concentrations.
Nonetheless, you're encouraged to stay indoors while the trucks are spraying.
