Một hợp chất mà giết chết sinh vật bằng đức hạnh của các tác dụng sinh học cụ thể chứ không phải là một chất độc hóa học rộng hơn. Cụ thể loại bao gồm sinh học, thuốc trừ sâu và thuốc diệt nấm sinh học. Thuốc trừ sâu sinh học khác từ các đại lý biocontrol trong đó thuốc trừ sâu sinh học đại lý thụ động, trong khi biocontrol đại lý đang hoạt động, tìm ra côn trùng bị phá hủy. Có một số tài liệu anti-pest cực kỳ hấp dẫn, chẳng hạn như độc tố <i>Bacillus thuringiensis</i> (Bt), mà cụ thể can thiệp với sự hấp thụ của các thực phẩm từ can đảm của một số côn trùng là vô hại cho động vật có vú. Lý do đằng sau phát triển thuốc trừ sâu sinh học là họ có nhiều khả năng được phân hủy và được nhắm mục tiêu vào các thành phần cụ thể của sự trao đổi chất của côn trùng.
