The only thing worse than bringing bed bugs into your home after a vacation is to have them come crawling over from your neighbor’s house. If you happen to live in a multi-unit housing complex, your neighbor is a potential source of bed bugs and can spread the creepy crawlers throughout the building without even knowing it.
The mode and frequency of bed bug movement within and between apartments are the most significant findings of a new study from the Public Library of Science
(PLOS), published in the September issue of Discover
magazine. Here, entomologists from Rutgers University captured and marked bed bugs from six infected apartment units in New Jersey, released them, and then closely monitored them for 32 days to observe where they ended up.
After a week from the release, there were between 2,433 and 14,291
bed bugs in each of the monitored apartments. Even in the absence of a host and the chance of a blood meal, the marked bed bugs continued to be recovered 134 days later, while the naturally existing unmarked bed bugs, mainly large nymphs and adults, were still found 155 days later when the study ended.
