Aprehend is a revolutionary fungal bio-pesticide for the elimination and prevention of bed bugs. Aprehend is an effective, ready-to-use formulation containing the spores of a fungal disease that is deadly to bed bugs. Unlike chemicals, Aprehend usually requires only one application to provide long-term control and protection with minimal preparation or disruption to the homeowner. Used as a quarterly treatment, Aprehend will prevent the establishment of infestations in hotels rooms. Bed bugs are attracted to the sleeping area and will attempt to establish colonies close to the source of a blood meal. Strategic application around the rear perimeter of the headboard, base of the box spring, bed skirt, and rear perimeter of night stands and picture frames will prevent the establishment of a bed bug colony. Aprehend is composed of Beauveria bassiana fungal spores applied in a proprietary formulation. Aprehend is sprayed strategically in narrow bands (2 inch) where bed bugs are known to walk; direct spray contact is not necessary. Bed bugs of all life stages, sex or feeding status are eliminated within four to ten days following short-term contact with a treated surface. The fungal spores germinate within 20 hours of contact and then penetrate the cuticle of the bed bug and colonize inside, resulting in death. When a bed bug comes into contact with a treated surface, the fungal spores stick to its feet and body and are taken back to its harborage. The spores transfer easily between bed bugs by direct contact, targeting even bed bugs that do not leave the harborage. After 24 hours, spores on the bed bug will germinate, like seeds, and penetrate directly through the cuticle of the bed bug. Once inside, the fungal disease grows in the blood system, eliminating the bed bug within 3-7 days.
