Evaluation of Beauveria bassiana (Apprehend) as an Alternative to the Organophosphate dichlorvos (Nuvan ProStrips) for Bed Bug (Cimex lectularius) Control

Grants and Contracts Details


Bed bugs remain one of the most difficult indoor pests to control. Their recent resurgence has led to the use of a variety of control tactics, including the organophosphate (OP) dichlorvos (Nuvan ProStrips), which is commonly used indoors by both professional and homeowners. Therefore, it is critical to evaluate novel bed bug control strategies. One such strategy is the entomopathogenic fungus Beauveria bassiana (Apprehend). While entomopathogenic fungi are not new, their indoor residual use is. Therefore, I propose to conduct a comprehensive evaluation of Beauveria bassiana (Apprehend), evaluating what exposure is required for effectiveness, how environmental conditions impact residual performance, and if bed bugs can detect/avoid treated areas. This work will provide critical information to support the use of a new OP- alternative bed bug management active ingredient
