BUZZ OFF: Mosquito control measures begin soon in Kanata North

(via City of Ottawa)

To control nuisance mosquito growth in Kanata North and the surrounding areas, larvicide will be applied throughout the summer, beginning with ground applications April 21, and ending September 15.

Kanata North Nuisance Mosquito Control Program deals with treating mosquito larvae in wetlands so they won’t hatch. No part of the program involves targeting adult mosquitoes.

Contractors, hired by the City of Ottawa, will do daily ground applications of a liquid larvicide in selected areas throughout the program. The application of granular larvicides through the air, by helicopter, is expected to take place sometime in the next two weeks.

The program will use Bti, (Bacillus Thuringiensis Israelensis) and Bs (Bacillus Sphaericus), which are naturally-occurring bacteria, that is dropped directly into the water where the larvae are found. Feeding larvae draw it in with the water, which stops them from becoming adult mosquitoes.

The Health Canada Regulatory Agency states that Bti and Bs have no effect on humans, birds, fish, animals or other insects, but destroys the stomachs of mosquito larvae that hatch in water.

Quality control includes weekly monitoring at five sites. There will also be post-treatment larva surveillance and extra applications of larvicide if needed.

The treatment area map and program details can be found on ottawa.ca. For further information about the larvicide application contact GDG Environnement or call, toll free: 1-877-227-0552.

Notice to Kanata North residents re: mosquito control program

(via Councillor Marianne Wilkinson)

IMPORTANT NOTICE RE: NUISANCE MOSQUITO CONTROL PROGRAM And Change in Meeting Dates (For Residents of Kanata North Only)

NEXT WEEK A MAILING WILL BE PROVIDED TO CANADA POST FOR DELIVERY TO ALL HOMES IN KANATA NORTH (except for high rise buildings).  This mailing should be received early in February.  Several meetings will be held to discuss the contents of that mailing and to provide information on the voting procedure for this program.  The meeting dates have been changed from earlier dates and additional meetings will be held if needed.

Note: If you do not receive the mailing in your mailbox by February 3rd (the envelope is marked “BALLOT ENCLOSED FOR MOSQUITO PROGRAM IN KANATA NORTH”), please contact my office.  Completed ballots must be returned by February 16th at 4 pm, so if you are mailing, do so by February 9th.

While we don’t generally think about mosquitoes in winter, when spring comes, they will be back!  The Carp River Restoration Project, now under construction, includes four new wetland areas, adding potential mosquito breeding grounds. Traps were used last summer to measure mosquito populations. Large numbers were found all across the Ward.  Parks, including soccer field areas, had particularly large numbers.  Hence, work is required throughout the Ward to reduce numbers of mosquitoes and to retain property values.

The program is explained in the mailing and you can link to it on my website (click here).  Similar programs have been underway in other communities for over 30 years.  I strongly recommend that you attend one of the meetings to find out more.  GDG Environment – the company that won the procurement, subject to a community vote, presently does a similar program in our area specifically for mosquitoes that carry the West Nile Virus (we have about 40 different types of mosquitoes in this area). At the meetings GDG will provide details on programs they have implemented in other cities, including Gatineau.

Councillor to install bat boxes in Kanata North to combat mosquitoes

You may have read in the news this week about residents who live near Kizell Pond in Kanata who want the city to do something to reduce the number of mosquitoes in their area.

CBC Ottawa reported that over 300 people signed a petition asking the city to take action.  “When you open your screen door or get out of your car, it’s just instantly, you get a [swarm] of mosquitoes just attacking you,” said Lianne Zhou, who started the petition.

Councillor Marianne Wilkinson revealed a few plans of her own in in an email update to residents:

Although mosquitoes are an increasing nuisance in the communities surrounding the Kizell Wetlands, this provincially protected wetland cannot be stripped clean of producer species (such as mosquitoes), which sustain the food chain. Chemical spraying would require provincial licensing and agreement by all the affiliated landowner(s), including the wetlands in question which are designated as provincially significant. According to GDG (a company that is hired by the City to treat catch basins and storm water ponds for mosquitoes carrying the West Nile Virus, an immediate solution is not possible for a treatment option – it would be at least a year away.

However there are some things that can be done now.  I have obtained 20 bat boxes that will soon be installed along the edge of the wetlands so that the bats (that are already in the area) will eat mosquitoes closer to people’s homes.  We may also be able to increase the number of dragonflies, although they eat many types of insects so it isn’t a total solution.  Individual homeowners can take action as well by ensuring no standing water (check your rain barrels, eavestrough, wading pools etc to ensure they are dry or have a screen at the surface to stop mosquitoes from laying larvae.  Commercial products such as the Mosquito Magnet, concentrated garlic spray, fogging materials are available at local hardware stores.

I contacted a senior entomologist in Winnipeg (mosquito capital of the world!) and I am getting some information on another effective way for homeowners to get rid of most of the mosquitoes. I will pass on that information once received.

I have met with City staff and they have agreed to move forward to build the Kizell Wetlands pathway but construction will not happen until at least next year. The first step – activating the project – is now underway. The other pathway, between Kanata Estates and Richardson Ridge, which will connect to the Kizell Wetlands pathway, is to be built by the developers of the Richardson Ridge community.
