Mosquito Attraction Index by Outdoor Light Type
Relative mosquito attraction index (0–10) for six common outdoor lighting types, ordered from lowest to highest. Combines direct phototactic response and indirect insect congregation effect. Lower = less stimulating. Color-coded: green (best choice) → orange (moderate) → red (avoid).
Higher Attraction (Avoid)
Best Choice
Warm amber LED (2700–3000K) — long-wavelength output outside peak mosquito visual sensitivity
Avoid
Cool white LED & incandescent — broader spectrum and heat emission increase insect response
Myth Busted
UV zappers score low for mosquitoes specifically — they primarily kill moths and non-target insects
