Transboundary pests present a significant threat to agricultural production and household incomes, with desert locust invasions being among the most disruptive. Despite ongoing control efforts, such as surveillance and chemical interventions, the rapid spread of locusts into non-traditional breeding areas and limited preparedness underscore the need for integrated desert locust management. This study aimed to identify indigenous locust control practices and examine the factors influencing their adoption to support informed policy for integrated pest management. Using a multivariate probit model (MVP) corrected for selection bias, we assessed factors affecting the adoption of these control methods. Data from a random sample of 473 farmers in Isiolo and Meru counties, Kenya, revealed that desert locust control methods are complementary, meaning that they are more effective when used together rather than in isolation. Key factors influencing adoption included access to information, experience with previous pest shocks, and social networks. These findings emphasize the importance of establishing effective early warning systems and enhancing farmer training on locust management through social groups as strategic entry points for intervention.
