The key difference between Aprehend and other biopesticides developed for use in agriculture is the formulation. Aprehend is a unique, ready-to-use formulation, which contains a special combination of oils, which enable the application of the Beauveria conidia (spores) to surfaces where they remain attached until encountered by a bed bug. This proprietary oil formulation ensures that Aprehend is effective even at very low (< 20%) relative humidity. The conidia remain dormant on the sprayed surface, and will only germinate when they come into contact with a bed bug. This is how Aprehend remains effective for up to 3 months after application. All agricultural formulations are designed to be diluted in water and sprayed at high volumes directly on insects that are feeding on plants. Once conidia have been in contact with water, they germinate quickly and if they are not in direct contact with an insect they will die.
