Abstract: A self-contained entry device for use with a bottle for preferably trapping roaches and similar crawling insects. The entry device comprises a mesh material shaped to form a truncated cone having a narrow strip extending from the larger opening of the cone. The smaller opening of the cone, preferably having an oval cross section, is inserted firmly into the mouth of a bottle or other receptacle containing bait for the insects. The narrow strip, extending from the larger, non-inserted opening, functions as a ramp allowing insects to crawl into the entry device and subsequently gain entrance into the bottle. Once inside the bottle, insects cannot maneuver themselves back through the smaller opening due to its size, shape and position within the bottle.
