Light and mosquitoes: what really attracts them in the evening

No: light does not directly attract mosquitoes. They are guided toward you by the CO2 in your breath, body heat, and lactic acid from your skin. To limit other flying insects in the evening, place a warm amber LED of around 2700 K near openings instead of a cool white light.

Does light really attract mosquitoes?

No. Female mosquitoes locate their target thanks to the carbon dioxide you exhale, the heat of your skin, and odors such as lactic acid from sweat. Turning on a lamp only helps you see those already present in the room.

Therefore, turning the light off or leaving it on changes almost nothing regarding their presence. Tiger mosquitoes bite just as much during the day as at night, regardless of ambient brightness. This is a point confirmed by entomologists, and one where the color of your bulbs can actually influence other insects. Choosing the right source from our lighting collection then becomes a concrete action.

The right approach depends mainly on the room and how you use it. This quick guide will point you in the right direction in seconds.

Do blue light and UV attract insects?

Yes, but not mosquitoes. Moths, gnats, and many other flying insects are strongly attracted by short wavelengths: blue, cool white, and especially ultraviolet. Warm amber light, however, is much less interesting to them. It is the spectrum, not the intensity, that matters.

Are insects attracted to blue light?

The blue and cool spectrum, above 5000 K, acts as a signal for many nocturnal insects. Therefore, a cool white bulb placed near an open window attracts more visitors than warm lighting. As for mosquitoes, they remain indifferent to this color.

Does UV light really attract insects?

Yes, ultraviolet is the most attractive of all. This is the principle behind UV light traps sold to combat flying insects. They capture moths and gnats but remain ineffective against mosquitoes, which are guided by CO2 and heat.

Does red light repel insects?

Red or amber light is the least perceived by most flying insects. It does not actively drive them away, but it attracts them far less than cool white. For a terrace or a bedroom, it is the most discreet choice come evening.

Which light should you choose in the evening to limit insects?

Aim for a warm LED around 2700 K near openings and reserve cool white for closed rooms. Three indicators are enough: a low temperature in Kelvin, LED technology without UV emissions, and placement that keeps the source away from open windows.

Warm white or cool white: what color temperature?

Warm white, between 2200 and 2700 K, provides an amber light that is not very attractive to insects and more relaxing in the evening. Cool white is suitable for the kitchen or office, but avoid it near openings at night. Our guide on how to choose between white or yellow light details each room.

LEDs stand out here: they generate little heat, emit no UV, and come in all temperatures. Based on a survey of 250 pendant lights in our catalog on September 22, 2026, 82% are labeled LED, all guaranteed for 2 years and CE certified. Our LED luminaires thus cover both warm and cool needs.

Changing the bulb remains the fastest solution, with E27 or E14 bases depending on your existing fixtures. If you are renovating an entire home, switching to all-LED reduces consumption and eliminates the heat of old halogens.

Where to place sources to light terraces and balconies?

Keep light away from French doors: a bright source right above an opening will attract insects inside. On a terrace, prefer a warm halo on the periphery rather than a bright central point. True mood lighting relies on several low-level, dimmed sources.

Outdoors, the ingress protection rating matters as much as the color: aim for IP65 to resist rain and humidity. Our range of outdoor lighting meets this need, precisely where mosquitoes are most bothersome. To assemble the overall setup, this guide on lighting your terrace helps distribute light points effectively.

What attracts mosquitoes at night?

Carbon dioxide leads the list, followed by body heat and skin odors. Mosquitoes detect CO2 from several meters away, then refine their approach using temperature and lactic acid. Dark clothing colors and perspiration further accentuate attraction.

CO2 and body heat

You breathe, you release CO2: it is the primary signal captured by mosquito antennae. Skin heat and humidity then guide them to bite. Lowering the light doesn't change this; managing ventilation and covering skin does.

Why are some people bitten more than others?

Sweat composition, blood type, and the amount of exhaled CO2 vary from person to person. A more active metabolism or skin richer in lactic acid attracts more mosquitoes. The light from your bedside lamp does not enter the equation.

Still, the right lighting transforms a summer evening: warm, LED, well-placed. To go further, our 2026 lighting trends show how to combine comfort and discretion in the face of insects.
