Invention regards a device (2) for detection and elimination of pest insects, wherein said device comprises a structure (20) having a main portion (22) adapted to engage with a supporting surface. The structure (20) has a main portion (22) with a thereto associated edge (23), said main portion being adapted to at least partially engage with a supporting surface, the structure further comprising a first flap (24) attached to said main portion, where a first flap edge (28) is associated to said first flap. Said first flap (24) is arranged so that said edges (23, 28) define an opening (33) for allowing entry of an insect such as bed bug into interior of the structure (20), said interior being substantially delimited by the main portion (22) and the first flap (24). At least one aperture (35) is arranged in the main portion (22) of the structure. Said device further comprises a double-sided adhesive strip (36) an upper face (30) of which is arranged on a face of the main portion that faces the supporting surface such that said adhesive strip completely covers the face of said one aperture, and an insecticide (34) in powder form that at least partially fills the at least one aperture arranged in the main portion. Invention also regards a roll with elements for assembling said device.La présente invention concerne un dispositif (2) pour la détection et l'élimination d'insectes nuisibles.
