What color are cockroaches most atrackted to?
Ans: 95…, Cockroaches (and most other insects) have two light receptors, one sensitive in the ultraviolet range and one in the green range. Many insects also have a third light receptor peaking in the blue. Most pest cockroaches are not attracted to light. They are active at night and if anything they might avoid light. However, if you have a patio that is lit you might be asking what type of light should you have in your patio lighting scheme. The yellow ‘bug’ lights would be least visible to any of the wild cockroaches that can see light and fly and often are attracted to porch and patio lights. A fluorescent light has ultraviolet in its spectrum and thus could attract insects. A normal incandescent light will have the usual blue and green light in its spectrum and thus attracts insects that see that light. The actual question of whether they are attracted to the light is another issue. Insects attracted to porch lights are often exhibiting the “moth to a flame” attraction phenomen
