First The Flooding, Then The Mosquitoes (VIDEO)

Fraser Valley -JUNE 4 UPDATE – The FVRD has been busy working on mosquito control since April in this high flood water year. Increased river levels and seepage water along low lying areas has resulted in conditions for abundant mosquito habitat.

Every year the FVRD monitors, maps and treats mosquito breeding grounds. The FVRD has already waged several aggressive aerial and ground treatment campaigns along foreshore of the Fraser River in a preemptive strike on the expected nuisance mosquitoes. The FVRD will continue to combat areas along the Fraser river that may experience a strong mosquito presence until no further mosquito larvae can be found.

The FVRD treats sites with non-toxic methods to preserve and enhance biodiversity, and does not conduct fogging or spraying for adult mosquitoes.

To assist in mosquito control, you’re advised to minimize standing or stagnant water in and around homes and businesses.

– Clean up and empty containers where water collects such as tarps, tires and flower pots.

– Remove water that collects on pool covers.

– Change bird baths and pet bowls often.

– Maintain and chlorinate swimming pools.

– Empty and turn over kiddie pools, wheelbarrows and small boats.

– Cover rain barrels with fine mesh.

– Keep lawns short and clear out dense shrubbery.

– Maintain your gutter and remove debris to ensure proper drainage.

It is best to avoid being outdoors at dawn and dusk when mosquito presence is at its peak. If you must be outside at peak mosquito time, wear light coloured, loose fitted clothing that fully covers your skin. Use fans to keep air moving around you. And know that things will get better soon.

MAY 30 ORIGINAL STORY – So this year’s freshet is dying down and the Fraser and Vedder Rivers and slowly getting back to normal.

That’s the good thing.

The down side are the pools of stagnant flood water. That makes for perfect breeding grounds for those lovely, pesky, annoying little critters.


Feeling itchy and scratchy yet?

FVRD, Fraser Valley Regional District saw this one coming (as you expect) and Morrow Bioscience Ltd. have been busy treating mosquito larvae several times already this season.

Responding on social media to complaints, and in particular, Deroche, the districts response: The FVRD and Morrow Bioscience are doing extra treatments this year because of the high river levels caused by the freshet. You can expect it’s going to be a very active mosquito season, no matter how much treatment we do. It’s such a big area to treat.

The FVRD wants residents to know that they are continuing to monitor and treat nuisance mosquito larvae that are present within seepage and flood waters. This is in addition to the aerial and ground treatment campaign already waged along the foreshore of the Fraser River.

The FVRD does not conduct fogging or spraying of chemicals that kill flying adult mosquitoes.

Stacey Barker, deputy director of regional programs: “Floodwater sites are treated with a non-toxic bacterial larvacide that specifically targets the mosquito in its larval stage before it can fly, this bacterial larvacide is an effective and environmentally sensitive method of controlling nuisance mosquitoes without harming other species.”

While the program is effective at reducing mosquito populations across the region, residents are encouraged to help out by reducing mosquito breeding sites near their homes:

  • Check for and eliminate sources of standing water such as saucers under flower pots, bird baths, old tires, pet dishes, gutters, pool covers, trampolines, tarps, etc.
  • Maintain and chlorinate swimming pools.
  • Empty and turn over children’s wading pools when not in use.
  • Cover rain barrels with fine mesh.

For mosquito control inquiries or to report mosquito breeding sites within the Fraser River corridor, call the FVRD’s Mosquito Hotline at 1-888-733-2333 or send an email to Residents can also stay informed of mosquito treatment by following Morrow Bioscience on Twitter @morrowmosquito) or on Facebook (facebook/com/morrowmosquito).

Here are “before” and “after” videos from the FVRD which show the mosquito control program.
