Hamilton's aerial assault against gypsy moths will continue Tuesday.

It will take another three days for low-flying helicopters spraying bio-pesticide to complete a second pass over areas at risk from the larvae of the invasive pest, which can strip entire trees and forests, according to Jeff Speir, the city's manager of forest health.

Spraying is scheduled to take place between 5 a.m. and 7 a.m. on Tuesday and Wednesday. The date for a third and final spray has not been set.

Pesticide not a threat to people or pets

The pesticide uses a bacteria that needs to be ingested by the caterpillars before it can be activated, so it doesn't have any impact on humans, bees, pets or any other animals.

Areas where spraying is taking place could see rolling road closures to avoid drivers becoming distracted by the choppers — check out the city's interactive map for more information.

The spraying is part of $2.5 million the city is spending to fight the moths.
