In the preferred embodiment, the invention is a trap for luring, trapping, and killing insects. The trap preferably includes: a single structure container defining a cavity that holds liquid, an opening that allows access to the cavity, a side wall, and a lid that seals the opening of the container. The side wall includes an orifice in the form of a frusto-conical shape that allows ingress of insects into the container and prevents egress of insects from the container. The side wall also includes a landing surface that directs insect towards the orifice.
