Prepare for another season of forest tent caterpillars in Saskatoon.
The city is in the midst of an outbreak of the caterpillars for yet another year, according to Saskatoon’s pest management supervisor Jeff Boone.
Outbreaks of the caterpillars typically last between three to seven years, with the insects returning in high numbers each summer of an outbreak.
This is the fourth year for the outbreak in Saskatoon, Boone says.
He says the city does not formally track forest tent caterpillars, but notes people have been reporting higher than normal numbers this year.
The caterpillars can remove the leaves from trees, but trees normally recover, according to the city. The city does not control the insects.
