Bed bugs are one of the only animals on our planet known to get stronger by inbreeding. A recent study has come to terms that bed bugs are fighting back against us humans by inbreeding.
New research on the bed bug’s ability to withstand the genetic bottleneck of inbreeding, recently announced at the American Society of Tropical Medicine and Hygiene (ASTMH) annual meeting, provides new clues to explain the rapidly growing problem of bed bugs across the United States and globally. After mostly disappearing in the US in the 1950s, the common bed bug (Cimex lectularius) has reappeared with a vengeance over the past decade. These stubborn pests have developed a resistance to the insecticides, known as pyrethroids, commonly used against them.
One of the newly discovered factors that appears to be contributing to the bed bugs’ effective infestation is their ability to establish new infestations through inbreeding. Coby Schal, PhD, and Ed Vargo, PhD, both entomologists at North Carolina State University (NCSU), and colleagues carried out two studies now under peer-review examining the genetics of bed bugs from three multi-story apartment buildings in North Carolina and New Jersey, and determined that there were high levels of relatedness within each apartment and very low genetic diversity within each building, indicating that infestations start from just one or two introductions of the insect. Being able to withstand a very high level of inbreeding — i.e., still produce healthy offspring — allows the bed bug infestation to expand to other apartments within the building.
Another study by this team confirmed this same conclusion based on a study of 21 bed bug infestations from Maine to Florida in the US, nearly all of which came from single rooms within homes. “Inbreeding gives bed bugs an advantage in being able to colonize,” said Schal. “A single female that has been mated is able to colonize and start a new infestation. Her progeny and brothers and sisters can then mate with each other, exponentially expanding the population. With many organisms, extensive inbreeding would cause serious mutations that would eventually bring about an end to the population.” He also noted that cockroach populations are also able to survive inbreeding.
A major strategic advantage that we might want to explore in this bed bug fight, and it may seem unproductive at this time, but may pay a huge benifit in the future is to introduce female bed bugs into the mix that do not have a resistance to any chemicals. This would, in theory, create colonies of bed bugs that do not have any resistance to our extermination procedures or chemicals.
Until then, there is really only one proven and effective way to kill bed bugs and that is heat.


Avoiding Bed Bugs This Holiday Season While Flying


If you are a building manager, property manager, or landlord this is a good reason to stay on top of any bed bug infestations reported to you by your tenants. If you do not take care of the bed bug problem promptly and in an efficient manner it could hit you where it counts, your wallet.
