Do Lights Keep Roaches Away?: Discover the Truth About Roaches and Lighting Solutions

Many people wonder if leaving the lights on at night can keep roaches away. The short answer is: not really. Cockroaches are nocturnal insects, meaning they are most active during the night and usually avoid well-lit areas. However, simply turning on the lights is not enough to get rid of them or prevent them from wandering into your home. Roaches may scatter when the lights come on, but given enough time—or if food and shelter are available—they will adapt and still come out even in lit rooms. A spotless, well-organized home design, focusing on minimizing hiding spots and food sources, is far more effective than relying on illumination alone.

From a designer’s perspective, strategic use of lighting combined with smart spatial planning can help highlight cleanliness and reduce clutter—both crucial deterrents for pests. In my own projects, I advise clients to integrate under-cabinet lighting, open shelving, and glass cabinetry. These choices not only add visual appeal but also make it harder for cockroaches to find dark, undisturbed spaces. Pairing thoughtful lighting with careful planning of your kitchen layout not only improves style but also enhances cleanliness and pest resistance—an approach where interior design truly supports healthier living.

Tips 1:

Declutter your home regularly, especially in kitchens and bathrooms. Proper storage can limit places for roaches to hide.
