City of Regina officials say cankerworm banding is an inexpensive, environmentally friendly and effective way to help stop cankerworm invasions.
It is advised residents band elm, Manitoba maple and fruit trees now.
Cankerworm bands should be kept in place until the end of May.
The City has banded close to 500 trees for monitoring and control.
The information will be used to determine cankerworm infestations in the city.
