“The bed bugs of today are descendants of those who survived DDT.”
One misconception that is so commonly bantered about and has taken on the air of being indisputable fact is the idea that the current bed bug upsurge is comprised of the descendants of dichlorodiphenyltrichloroethane (DDT) survivors. It’s a fact that bed bugs have a fantastic power to adapt by altering their genetic structures in a way that enhances their ability to remove toxins from their nervous systems and this ability keeps pest control professionals in a constant state of learning and adapting to stay ahead of the curve. But it is true that some populations of these insects were beginning to exhibit resistance to DDT toward the end of its use. But it’s not necessarily established fact that today’s bugs are all descendants of those resistant ancestors. Furthermore, the descendants of those bugs have lost much of their resistance to the chemical through interbreeding. The bed bugs that we’re dealing with today are not necessarily derived from those populations.
