Rats a growing problem on southern Vancouver Island, says pest control expert
Rats are a growing concern on southern Vancouver Island, where their numbers are increasing and residents are reporting damage to their homes and vehicles.
“The rat population is increasing,” said Christopher Day, the Vancouver Island branch manager for pest control company Orkin Canada.
When people were working from home during the pandemic, the majority of calls for service were for residential properties. “Now that people are going back to offices, we’re starting to get more commercial [calls],” said Day.
Rats have two main drives—food and shelter. With inflation driving up the cost of food, a lot of people are planting gardens and that is a veggie buffet for rats.
“A lot of people are getting into gardening,” said Shawn Jackson, department head at the Wildwood Outdoor Living Centre. “[Rats] will go and pilfer tomatoes and the odd bit of fruit but what they really want in the backyard gardens is the compost.”
As compost breaks down, it heats up. That is not only a food source but a nice place for rats to call home and reproduce.

“We always encourage people to do compost but it is an intensive system that has to be maintained,” said the department head.
Jackson recommends consistently turning over your compost or purchasing an enclosed system.
Kyle Beland is a mechanic at Ina Motors. He has seen the damage rats can cause to a vehicle’s wiring system.
“You’ll wake up in the morning and your car doesn’t run all of a sudden. It’s shaking and misfiring,” said Beland. “It’s because they’ve chewed all the wires that go to the ignition coil.”
Those wires are wrapped in a soy-based insulation, a tasty treat for rats. Depending on the extent of the damage, a fix can be expensive.

In July 2021, the province embarked on an 18-month trial, banning the use of second-generation anticoagulant rodenticides in many circumstances. The reason for the ban was that wildlife were dying after ingesting poisoned rodents.
That has prompted pest-control companies to adapt, often by using traps.
“It is more labour-intensive, so more labor means more time, more time means more money,” said Day.
The trial is set to expire in January.
With fall fast approaching, rodents will be looking for a warm place to live. Day says a mouse is able squeeze its body through a hole the size of a pea, while a rat can squeeze its body through an opening the size of a dime.
Day recommends rodent-proofing homes now in order to protect property from an increasing rat population.
