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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
