Mosquitos 2023: Discussed at TIRRA member meeting June 29th

Historically, Thetis has enjoyed a relatively mosquito free environment. However, in some years the weather is just right (warm, wet, little wind) to result in what seems unbearable invasions.

The concentration of the pests are different throughout the island, as noted by those who walk or cycle. This begs the question, why?

Mosquitos generally only travel 1.5 to 3 miles from breeding site. Breeding sites are natural areas of water seepage, open drainage grates, unscreened water barrels, or other "containers" with sufficient water for pupae to proceed to adult mosquitos.

As some of you may be aware, the drainage ditch near Marina Road and Pilkey Point (the cut) is currently not controlling mosquitos by curbing flooding on the north side: the culvert and flap as well as the ground under the culvert need some work which will cost $13K+. Ministry of Transport is not responsible for mosquito control and therefore Thetis Islanders will need to figure out how to foot the bill and complete the repairs. This will not be able to be accomplished this year.

If you are experiencing high levels of mosquitos in your yard: engage with your neighbours to review the properties and consider whether there could be water sources contributing to breeding. Always ensure gutters are clear, stored boats, old tires, anything that can hold water are empty and dry.
