Why don't bed bugs like light?

Because bed bugs are nocturnal they are more likely to be lurking in the dark to avoid the light that can awaken them. Once it becomes light out, bed bugs move to their daytime resting places, such as beds, couches, chairs, and boxes. Bed bugs are also more likely to be active when it is hot and humid outside.

Bedbugs don't like light?

Although bedbugs do not like light, they are not completely blind to it. In fact, bedbugs have a sophisticated light perception system. They have pigment-filled photoreceptors on the upper rim of their heads called eyespots. Each eyepot contains about 30 pigment cells that respond to light. These cells are specialized to detect infrared light, which is most reflected by the earth’s surface. This allows bedbugs to see whether it’s daytime or night-time outside.

Bed bugs don't like bright light?

Well, bed bugs aren’t blind, so they’re not bumping into furniture or walking into walls because of poor eyesight.

Humans aren’t attracted to light, but bed bugs might be more likely to bite you if you’re moving around a lot and bump into things in your room.

Why don't bed bugs like light bulbs?

Bed bugs have no need for light to find a warm, comfortable place to rest. Their bodies are perfectly designed to find shelter in dark places to avoid detection by their predators. Furthermore, bed bugs have pigment-rich “eyes” that are sensitive to light. Stimulating these eyes can trigger the bed bugs’ urge to bite and cause them to emit distinct pheromones.
