Intrusion by wild animals is the biggest concern for farmers, and during the harvesting season, protecting crops is one of their greatest worries. Wild animals, especially boars, are the greatest threat, as they not only eat the crops but also dig up the farmland in search of roots and insects to eat. Moreover, this species tends to visit farms in groups, which can cause significant damage to crops, resulting in substantial financial losses. This study focuses on finding a long-term solution to this problem. An Automated Aversion Unit (AAU) is proposed in this paper and is tested at various locations with different features. The proposed unit is economically viable and can be installed in remote areas without requiring continuous monitoring. During a 15-day short-term observational field trial without randomized control plots, the device demonstrated a substantial reduction in wild boar intrusion frequency, with reductions of up to 95% relative to baseline conditions. The study demonstrates the AAU’s short-term effectiveness in reducing wild boar intrusion; however, long-term habituation resistance requires extended seasonal trials.
