A trap monitoring the presence of insects is a closed box comprising a chamber with an attractant lure, glue on the bottom and openings located at the bottom of the trap, said openings being connected with input channels created at the bottom of the trap. A line made of glue is laid onto the bottom of the lower part in order to catch insects. The trap is used for monitoring the presence of crawling insects like Tribolium flour beetles, granary weevil (Sitophilus granarius), silverfish (Lepisma saccharina), firebrat (Thermobia domestica) and others.
