A cockroach trap is constructed to attract and kill cockroaches by providing a confined space between nested metal cups and including means for heating the space continuously to a first temperature such as 70°to 90°F. that is attractive to cockroaches and periodically heating to a temperature such as 180°to 200°F. that kills them. The two cups are stacked one inside the other with spacers between the cups. An electrical heating element is disposed circumferentially around the outside of the outer cup to provide the first temperature, and other elements in heat transfer relation with both of the cups providing the second temperature. Attractants such as pheremones, food scraps, or bait, along with water, may be provided at the bottom of the confined space. The inner cup may be readily lifted out to enable removal of dead cockroaches.
