Are Bedbugs Contagious?
Bedbugs are not contagious. Though bed bugs can theoretically be passed from person to person, the likelihood is low. It is more accurate to think of them as stowaways, rather than as contagious.

How Bed Bugs Spread from One Location to the Next
Bed bugs hide where people spend a lot of time, such as in the folds of a mattress or an armchair. They are often transported from one place to another during travel. Bed bugs in a hotel mattress will hide inside luggage and subsequently be relocated at another stop along the travel route or directly to the traveler’s home. [1]
The Likelihood of Direct Person-to-Person Transfer Is Low
Bed bugs are not like lice or scabies that readily move from one host to another through person-to-person contact. Several characteristics of the bed bug make the likelihood of direct person-to-person transfer low. [2]
The bed bug doesn’t live on its host. Bed bugs are not like lice. Lice are highly contagious and will readily trade one human host for another, needing little more than close proximity to exchange hosts. Though they are similar in feeding on the host’s blood, people not sleeping move too much to make a good hiding place for a bed bug. [3]
The bed bug feeds for a brief amount of time. The bed bug will remain on its host until it becomes engorged, usually within 3-10 minutes. When they are finished feeding, they move from the host to return to a dark, hidden place to digest the meal. [4]
Most human contact is initiated at night. It is a myth that bedbugs won’t feed in the light. Though most human contact is initiated at night, this is because they feed when a person is sleeping. [5]
The bedbug is a homebody. The bed bug generally lives within eight feet of people’s sleep locations, such as a mattress or armchair. Though it will hitch a ride to a new location, it will seek out the same shelter in the new location. [6]
The bed bug doesn’t fly or jump. In the unlikely event that a bedbug is attached to a person while performing daily activities, it does not fly or jump, another factor inhibiting it from readily moving from one host to another. [7]
That Doesn’t Mean They Don’t Spread Rampantly!
Though direct person-to-person spreading of bed bugs is low, they are spread very easily through personal items carried from one place to another, such as from one school backpack to another. They are most often spread through items carried in travel, from one apartment unit to another, or from infested items that are discarded and unknowingly picked up by another, such as second-hand furniture.
