There’s been an increase in earwigs across Ontario this summer, and experts say it all has to do with the weather.
Alice Sinia, an entomologist with Orkin Canada, said last winter’s mild temperatures made it easier for more eggs and adults to survive. Additionally, the spring and summer’s wet, hot and humid conditions have created the perfect environment for the insects to thrive.
“We are seeing a lot more earwigs this year,” Sinia said.
“If you look at all the three factors – the temperature, the wetness and the humidity – it means there’s a lot of decaying organic matter, and that’s really what earwigs feed on. It’s really a perfect combination.”
They may not be the most popular insect with their six legs, antenna and pincers, but they do have some benefits.
“They help to decompose organic matter. Decomposition is very crucial because we need all the nutrients and nitrogen recycled in nature,” Sinia said.
“But most importantly, they’re also predators. They’re omnivores who feed on decaying organic matter but also on other insects.”
