Calgary’s hot and dry May has led to a spread of chinch bugs on city lawns.

Under such conditions, the insects tend to migrate from one property to another, leaving a destructive path that can kill a lawn in as short a time as one season.

Chinch bugs suck the juices from grass blades while leaving a toxin behind that results in dead patches of grass.

The cost of resodding a lawn can range from $6,000 to $10,000, depending on its size.


The best time for spray applications is mid-June, a Calgary lawn care professional says, but treatment could take more than one visit.
