The EPA summary on risk to human health is as follows:
When applied as a pesticide to control bed bugs indoors, EPA concludes that use of Beauveria bassiana GHA will not result in unreasonable adverse effects to humans. The new use will not contribute to oral exposures already evaluated for the agricultural use. EPA does not expect dietary (food and drinking water) or other non-occupational risks from the indoor use of B. bassiana GHA as an active ingredient in Aprehend. The incidental dermal/inhalation exposures from indoor use will be limited. Any occupational exposures to applicators handling B. bassiana GHA are expected to be minimized by label precautions and the use of the required PPE; which in addition, addresses the general concern for potential allergic sensitization for all microbial pesticides. It is not appropriate to aggregate dietary risk of other B. bassiana GHA products with the risks of dermal sensitization from Aprehend since the endpoints are different.
