The larvae stage of acronicta intermedia may contribute to allergies in a small number of people through contact with its hair. These allergies are typically mild, resulting in common symptoms such as itchiness or skin irritation. While the risk is not severe, individuals who are sensitive should handle acronicta intermedia with caution to prevent allergic reactions.

The larvae of acronicta intermedia possess hair that can cause mild allergic reactions in sensitive individuals when they come into contact with human skin. Such reactions include itchiness or skin irritation. Since acronicta intermedia larvae can be found in areas frequented by humans, the probability of coming into contact with these insects is not negligible, particularly for those engaged in outdoor activities in habitats where acronicta intermedia is prevalent.

To minimize the risk of allergic reactions, individuals should avoid direct contact with acronicta intermedia. Wearing protective clothing, such as long sleeves and gloves when handling plants or spending time in regions known to be inhabited by acronicta intermedia, can be an effective precaution. Additionally, keeping living areas clean to reduce the likelihood of acronicta intermedia finding suitable habitats nearby can be helpful.

If contact with acronicta intermedia occurs and results in mild allergic reactions, thoroughly washing the affected area with soap and water is advised to remove any irritants. Using a cold compress can help alleviate itchiness or irritation. Keeping living spaces well-maintained, avoiding the creation of inviting habitats for acronicta intermedia, and sealing gaps that may allow entry into home or property should also be considered. During recovery, it's important for individuals to monitor their condition and avoid further contact with the larvae.

As acronicta intermedia feeds, it chews through the tissues of its host plants, which include Alder, Birch, and Hazel. This feeding results in the distinctive consumption of leaves, leaving them riddled with holes or edges. The defoliation can impair the plants' ability to photosynthesize, ultimately affecting their growth and vigor.
