The City of Regina has a new and novel way of tackling aphids this year.
It has released 300,000 ladybugs to devour the pesky insect that damages the trees.
“They’re a problem with our trees, they suck the juice out of our trees, they cause problems with foliage and they cause stress on the trees,” explained Ray Morgan, the manager of parks and open spaces.
Pesticides are one solution but the city is making and effort to be more environmentally-friendly so instead, hungry ladybugs are seen as the answer.
“Their job, the ladybugs, is to eat the aphids,” Morgan said. “They start crawling up the trees and start devouring the aphids. It is a really effective environmental control.”
Ladybugs get around much better into the nooks of the trees and an adult ladybug will eat up to 50 aphids a day.
Roughly 100 kids joined in the fun of releasing the ladybugs. Each handed a dozen or more to place at the base of the trees in Victoria Park.
Focusing on public spaces specifically, 150,000 ladybugs were released in the downtown area with the other half dispersed at parks across the city.
The ladybugs were bought from California, travelling first to Toronto and then on to Regina. It cost the city $1,200.
Residents are encouraged to join in the ladybug fun and order some online to release in their own garden.
