After analyzing the results, scientists found that bed bugs were twice as likely to latch onto the dirty laundry than the clean laundry in the room with the CO2. In the room without COS, bedbugs “were more likely to leave their refuge and initiate host-seeking behaviour,” scientists said in an article about the study.
Scientists believe when bedbugs cling to clothing, the critters can easily travel from place to place, which causes them to spread. To prevent an infestation, they think travelers should carefully store their clothing, keeping them away from beds.
"Our study suggests that keeping dirty laundry in a sealed bag, particularly when staying in a hotel, could reduce the chances of people taking bed bugs home with them, which may reduce the spread of infestations," lead author William Hentley said in a statement.
Such prevention tactics can also help reduce extermination costs as bedbugs can be extremely difficult to get rid of.
