What Causes Bed Bugs
Despite what some people may think bed bugs aren’t caused because of dirty or filthy conditions. They are also not some remnant from a plague centuries ago. They exist for one one reason – to survive off of the blood of humans.
If you want to understand bed bugs you must first understand that their only source of food is blood. Bed bugs that are most often found in homes need human blood to both live and to breed. Unlike other bugs, bed bugs don’t have the ability to leap or to fly so in order to get to their food source they find ways to attach themselves to humans and our belongings in order to be transported.
Bed bugs seek out places where humans nap or sleep. They are typically nocturnal creatures, active at night when humans are asleep. Most experts agree that bed bugs are able to sense body heat and the carbon dioxide we emit when we breath. Once a human host is asleep, they then crawl onto skin and feast themselves on our blood.
