Regina City crews are out spraying for tent caterpillars and canker worms this week in several neighbourhoods.
The city says crews aim to spray 2,000 trees this year, though last year they were able to spray 13,000 trees.
City spokesperson Russell Eirich says while trees can take some damage, it’s important to make sure they are taken care of.
“A tree can take defoliation over a year or two, but when you get that constant, repeated defoliation it starts to weaken the trees (and) starts to make it more susceptible to diseases.”
Eirich says there’s a difference between the two insects.
“The canker worms, generally speaking, like to feed on the elm trees, the tent (caterpillars) are going to go after poplar, they’re going to go after some birch, they’re going to go after some fruit trees, and ash trees.”
The city also provided an update on mosquito conditions, saying with the dry conditions the numbers are significantly down.
