The city health department is scheduled to spray pesticides for the sixth time this year to prevent the spread of Zika and West Nile viruses.

Trucks are expected to spray parts of Brooklyn and Queens between 10 p.m. and 6 a.m. on Tuesday and Wednesday.

Officials said no trace of Zika has been found in any local mosquitoes and that the spraying is just a precaution.

They also said the pesticides do not pose significant health risks, but residents should stay indoors during spraying.
