Grasshoppers – Survey and maps

Methodology
The 2025 grasshopper survey map is based on adult grasshoppers counts conducted in late July and August 2025 by the Agricultural Fieldmen of Alberta. A total of 2,195 fields were surveyed across the province in 2025.

The adult grasshopper counts give an indication of the number of individuals capable of reproduction and egg laying. Environmental factors can result in higher or lower actual populations than forecast. Individual producers need to be aware of the potential risks in their area and monitor fields accordingly and then make the appropriate decisions if control measures are required.

2026 spring update
Overwintering conditions only cause grasshopper mortality in very extreme winters with low snow cover. This winter was generally mild, so we do not expect significant grasshopper overwintering mortality.

Fall conditions were favorable for grasshopper egg laying over most of the province. Spring hatch will depend on the number of grasshoppers in the area last fall and early spring conditions. Be prepared to scout for grasshopper nymphs, especially if spring 2026 is warm and dry.
