The moths, which have established themselves in the St. Vital area, are an invasive species and can devastate trees.
St. Vital Park has a large native oak tree population.
The aerial treatment take place between 5 a.m. and 7:30 a.m. CT in the park and in parts of the Minnetonka and Pulberry neighbourhoods, according to the city.
Planes will administer two more treatments sometime between mid-May and late June.
