The use of mosquito larvicide in Sparwood nearly tripled in May from the same time last year.
This following a recent report that the District used 35 treatments of larvicide over the course of May, nearly three times the amount used in the same time last year.
The pests are being found in nearly all areas around the community, due to rivers running high last month.
Director of Engineering Danny Dwyer says a heavier than normal snowpack and high river levels created ample breeding grounds for the insect.
“Our consultants or contractor had predicted it and we certainly noticed it,” Dwyer says. “This year, we began aerial treatment again and we haven’t done that for a few years. We don’t treat willy-nilly, we treat when the levels reach a certain threshold.”
Dwyer says with the snowpack returning to normal levels, populations will hopefully drop.
“If we have wetting, where additional mosquito eggs are freed up and hatched, then we can expect to have a bad year,” Dwyer says. “If it gets warm and dry sooner, then it will taper off. So it is all weather dependent.”
Ongoing control efforts are targeting larvae sites throughout the district and treating them with an agent.
Dwyer says they will begin sampling mosquito populations on a weekly basis in July.
