What Are Bed Bugs and Their General Impact on Humans?

Bed bugs are small insects that feed on human blood. They’re mostly active at night, biting exposed areas of skin while individuals are asleep. Sounds creepy, right? However, contrary to popular belief, bed bugs do not transmit diseases. They can, however, cause physical and psychological discomfort, disrupting much more than just your sleep.

How Do Bed Bugs Interact With Humans?

Bed bugs exist in small crevices and only come out to feed under the cover of darkness. They are attracted to the warmth and CO2 emitted by humans. These tiny intruders are experts at hiding and virtually impossible to detect until there’s an infestation. Their interaction with humans involves biting and feeding on human blood, often causing itching and skin irritation.

This irritation can turn into a bigger problem as scratching can lead to secondary skin infections. Additionally, although bed bugs aren’t considered a public health hazard, they indeed cause mental distress like anxiety and insomnia, affecting your overall well-being.
