Social media video of rats in downtown Vancouver renews debate over pest control

A videoof a large group of rats near the BurrardSkyTrain station in downtown Vancouverhas sparkedconcerns about a rise in pests in the regionanda debate about whetherchanges in regulations around rat poison in theprovince are contributing to the problem.

The video was posted tothe online discussion website Reddit, sparking a number of comments aboutthe rise of the rodent population in different parts of Metro Vancouver.

Jay McIntyre of Solutions Pest Control, who has worked in Metro Vancouver for almost two decades,says there hasbeen an increase in service calls for rats over the past two years.

"We're getting rat calls in places we've never really gotten that many before," McIntyre told CBC News. "And usually by the time the clients know it, it's an established population. It's not one or two, it's seven or more."

Following the ban of most rodenticides in B.C., Jay McIntyre of Solutions Pest Control says rat and mice populations have boomed in the province. He tells CBC's Joel Ballard that traps, and sanitation and exclusion methods are now being used to keep rodents out of businesses and homes.

In January 2023, B.C. adopted a new regulation prohibiting the sale and use of second-generation anticoagulant rodenticides (SGARs) for all members of the public and most commercial and industrial operations.

Thechange came about because owls and other wildlife that feed on rodents were also dying from the poison.

Kaylee Byers, a senior scientist with the Pacific Institute on Pathogens, Pandemics and Society at Simon Fraser University,says it's unclear whether the regulatory changes havecontributed to a ratpopulation boom.

Byers says she is aware of an increase in chatter around the rats, but cites the old axiom that correlation is not causation. Just because the ban on SGARs happened around the same time as an anecdotal growth in the population, she says,doesn't mean they are linked.

The bigger issue, Byers says, is a lack of data.

"We don'thave a way to track rat populations over time," she said.

She notes that tracking rat populations is complex, and would require buy-in from the general public to report sightings. She said Vancouver residents can report sightings tothe city's 311 hotline, which provides access to municipal services,but it's not set up to be a systematic way of tracking the rat population.

The City of Vancouver says there were 1,174 cases involving rats reported to 311last year.

In 2022, there were 1,249 calls involving rodents and 1,175 in 2021, but those numbersinclude all mentions ofrats, mice and other rodents, not just rats.

The city said staff closely monitor rat-related calls, which areaddressed on a case-by-case basis.

A statement from B.C.'s EnvironmentMinistrysays it amended regulations because SGARspose "a serious risk to children, pets and wildlife through direct and secondary poisoning."

"Simple rodent prevention methods, like rodent-proofing buildings and cleaning up rodent attractants, are more effective and sustainable pest prevention methods," the statement reads.

"When needed, other rodenticides (non-SGARs) and products (e.g.traps) are available to use."

McIntyre said the SGAR ban forced him to adopt a new way of thinking.

"It was sort of easy, a crutch," he said of SGARs. "Then it was like, oh, we don't have the poison to deal with these rodents anymore.

"But we can still control them with traps, exclusion, and proper sanitation around garbage bins."

Exterminators say unseasonably warm weather and a ban on using rat poison are among the likely reasons that Vancouver is seeing an increasing number of rats.
