Bed bugs in Toronto: A 19th century pest re-emerges in the 21st century

Resurgence may be due to greater resistance to pesticides, socioeconomic conditions

"Bed bugs were once a common urban plague. But with the development of synthetic insecticides such as DDT and spray systems during the Second World War, they were largely eliminated," says Dr. Tim Myles, an urban entomologist and author of the study published U of T’s Centre for Urban and Community Studies in a recent research bulletin.

Reports of bed bugs by Toronto pest control companies and pest control officials started to increase two years ago.



In 2002, homeless people told street nurses that bed bugs were a priority medical issue. This year, at least a dozen shelters, hostels, and other forms of public housing had ongoing problems with bed bugs, despite spraying by pest control companies. "The situation merits attentive monitoring. At present, it is not clear to what extent, if at all, such monitoring is currently in place in the Toronto Public Health system," he says.

What is causing this new resurgence? At present, experts can only speculate that the following factors may be playing a role:
  • changes in registered pesticides, use patterns, residual levels, and pesticide resistance;

  • socioeconomic conditions leading to increased levels of homeless people living under conditions in which it is difficult to maintain hygiene;

  • a populace that has forgotten how to monitor for and control bed bugs;

  • greater mobility that allows bed bugs to spread more quickly to a wide number of establishments, including hostels, shelters, dormitories, prisons, hospitals, and hotels.

What can be done to eliminate bed bugs? The research bulletin not only mentions commercial pesticides, but also encourages greater awareness, early reporting, monitoring, cleaning efforts by rooming house and hostel residents, and Integrated Pest Management. Non-chemical approaches include thorough searching and mechanical destruction of bugs and eggs, along with laundering of bedding, frequent vacuuming, and brushing mattress seams. The bulletin also describes the effectiveness of sticky traps and even simple carpet tape, which, placed around a bed or bed legs can trap the bugs.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
