Bed bugs aren’t necessarily ‘caused’ by anything, they are simply brought into your home by someone or something that happens to have one or more bedbugs hitchhiking their way in. Here are some common sources of bed bug hitchhikers:
- Bugs and eggs that “hitchhiked in” on pets, or on clothing and luggage
- Infested items (such as furniture or clothing) brought into the home
- Nearby dwellings or infested items, if there are easy routes (through duct work or false ceilings)
- Wild animals
- People visiting from a source of infestation; bed bugs are transferred by clothing, luggage, or a person’s body
Bed bugs were for the most part eradicated in the developed world after World War II, and the recent resurgence has been linked to increase international travel, as well as changes in pesticides and pest control methods. Every kind of mattress, bed, and piece of furniture can house bed bugs – some more so than others. For example, memory foam mattresses don’t allow bed bugs to live inside the foam, making detection and elimination a simpler task.
