A trap for immobilizing, killing, or containing arthropods comprises a housing having walls and at least one opening, where the walls define an interior space； and a light source comprising a directional light source mounted in the interior space. The light source is constructed to emit light at one or more wavelengths ranging from 350 to 500 nm. The light source is positioned so that a majority of the light emitted from the light source is directed at one or more surfaces in the interior space. The trap also comprises a suppression element mounted in the interior space and constructed to immobilize, kill, or contain arthropods.
