During which months do most scale eggs hatch?

Most scale eggs typically hatch during the months of May and early June due to the warmer temperatures and increased availability of food sources that coincide with this time of year. As temperatures rise in the spring, many scale insects respond by beginning their reproductive cycles, leading to a peak in egg-laying. The hatching period aligns with optimal environmental conditions, such as the presence of tender new plant growth that provides a suitable habitat for the emerging scale nymphs.

Understanding the life cycle of scale insects is critical for effective pest management. Since their eggs hatch at this time, that's when control measures, such as the application of appropriate pesticides, can be most effective. Timing treatments to coincide with the hatching of the eggs can prevent scales from establishing themselves on plants, reducing future infestations. This knowledge helps applicators manage landscapes and ornamental plants effectively, ensuring plant health while minimizing pest issues.
