Does outdoor lighting attract mosquitoes to your business?

Does the type of outdoor lighting used affect mosquito activity at your business?

Mosquitoes aren't strongly attracted to light the way moths or flies are. Their main draws are carbon dioxide, body heat, and moisture. But lighting can still play a role. Artificial light disrupts mosquitoes' natural navigation, and certain bulb types are more likely to pull insects toward your building.

Traditional incandescent and halogen bulbs emit UV wavelengths that attract flying insects. Warm-white or amber LED bulbs emit far less UV light and are a better choice for exterior use. Culex mosquitoes, a common U.S. species and known vector of West Nile virus, are most active at dusk and dawn, so reducing UV output during those hours can help.

Practical steps for commercial properties:

• Switch to warm-white or amber LED bulbs for exterior lighting
• Position lights away from entrances and outdoor seating where possible
• Use motion-activated lighting to limit overnight hours
• Avoid placing bright lights directly above doors or near vegetation

These steps can reduce insect activity around your building, but they won't address the root causes. If mosquitoes are a persistent problem, professional mosquito control targets breeding sites, resting habitat, and adult populations for a more meaningful result.
