Coastal Ward city councillor David East has said this option would "obviate the problem altogether".
For years, Bromley residents have been surrounded by armies of midges during the summer months.
The Christchurch city council has spent $800,000 over two years trying to fix the problem to no avail.
Bromley resident Janet Profit is one of those who has been pleading for action.
She said residents wanted the problem "sorted, fixed" by the summer and their preference was for the UV treatment. "We know it's going to cost a lot of money but we don't want them reduced, we want them gone."
"They've paid $800,000 to do what? That money was absolutely wasted, it never worked and that really bugged us."
