A device (2) for detection and elimination of pest insects includes a structure (20) having a main portion (22) adapted to engage with a supporting surface. The main portion has an associated edge (23), the main portion partially engaging with the supporting surface. A first flap (24) is attached to the main portion, a first flap edge (28) being associated with the first flap. The edges (23, 28) define an opening (33) for allowing entry of an insect such as a bed bug into an interior of the structure (20). At least one aperture (35) is arranged in the main portion. A double-sided adhesive strip (36) has an upper face (30) arranged on a face of the main portion. The adhesive strip completely covers the face of the aperture. An insecticide (34) in powder form at least partially fills the at least one aperture arranged in the main portion.
