Which pests should be controlled from May to August?

Controlling armyworm and cutworm larvae from May to August is crucial due to their life cycle and feeding habits during this period. Both pests can cause significant damage to turf by feeding on grass blades, leading to severe thinning and even plant loss if not addressed. The larvae are particularly active and numerous during the warmer months, making this the optimal time for management practices.

Focusing control efforts during this timeframe aligns with their peak activity and life stages, ensuring effective intervention before they can cause extensive damage to cool-season turfgrass. Monitoring and scouting for signs of these pests during these months allows for timely treatment, making this the most effective approach to maintaining healthy turf.

In contrast, other pests mentioned, such as green lacewings and ladybugs, are beneficial insects and generally do not require control. Bluegrass billbug larvae have a different active season, typically showing issues earlier in the spring, while chinch bug adults peak outside of the May-to-August window, indicating that management strategies for these pests differ from those needed for armyworm and cutworm larvae.
