NOTE: Latest information and updates are noted below program information
The Kanata North Nuisance Mosquito Control Program targets mosquito larva found in wetlands to prevent hatching. The small, localized, program has been approved for four years from 2016 to 2019. GDG Environnement has commenced the first treatment and ongoing applications will be done to the treatment area in and around Kanata North. The control agents are Bacillus Thuringiensis Israelensis (Bti) and Bacillus sphaericus (Bs), which are a bacteria found naturally in soils. No other control agents will be used. The Health Canada Regulatory Agency has approved both agents and has found them to have no effects on humans, birds, fish, animals or other insects. Bti and Bs are effective bacteria that destroy the stomachs of mosquito larvae that hatch in water.
The treatment program poses little risk to the natural environment. Nonetheless, it includes a research project to detect any environmental changes to the area. The research project will be a partnership between the City’s Land Use and Natural Systems Unit, The University of Ottawa and GDG Environnement.
For more information
Any inquires that my office receives about the Nuisance Mosquito Control Program are being sent directly to GDG Environnment for immediate action. Nuisances can arise for various reasons and so an investigation needs to take place when we hear that the treatment is not working as it should. You can direct your questions/requests directly to GDG Environnment by phone at 1-877-227-0552 or by e-mail at email@example.com. This process is in place to increase the effectiveness of the program.
For all inquiries related to the research project, please contact Nick Stow, City of Ottawa Planning & Growth Management Department by email or 613-580-2424 ext. 13000.
For all other inquiries, please call 3-1-1.
August 24, 2017: Update from Councillor Wilkinson
GDG advised that with the rain we received on Tuesday, the Carp river has overflowed in some areas and there is a new generation of larvae. They are planning to do an aerial treatment either tomorrow (Friday) afternoon or Saturday morning (after 7 am). It will be done by an airplane this time as the helicopter is not available. The treatment will last approximately 30 min. They will install the signs accordingly. The Carp river is the only area where they will proceed with the aerial treatment.
Since Wednesday, they have been doing ground treatments and they have been able to access the Arcadia development land.
June 29, 2017: Update from Councillor Wilkinson
Despite regular treatment to keep the mosquito larvae from hatching the heavy rains that created larger flood plains and puddles everywhere, has meant that some larvae survived. GDG has retreated some areas and I met with them this week to review the program and get them to expand operations. Most mosquitoes in our area are floodplain varieties which can be dormant for up to 15 years. When the area floods they hatch so some areas are experiencing adult mosquitoes. A few landowners have not permitted treatment on their land which is why the program is based on an 80% reduction as not all larvae can be treated. To volunteer to observe one of the weekly monitoring tests please contact my office.
April 20, 2017: Public Service Announcement
Summary description: Nuisance mosquito control measures in the Kanata North area starts tomorrow, with ground applications.
Nuisance mosquito control measures in Kanata North starts tomorrow
Thursday, April 20 – To control nuisance mosquito growth in Kanata North and the surrounding areas, larvicide will be applied throughout the summer, beginning with ground applications on April 21, and ending September 15.
The Kanata North Nuisance Mosquito Control Program deals with treating mosquito larvae in wetlands so they won’t hatch. No part of the program involves killing live 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 and black fly larvae that hatch in water.
Quality control includes weekly nuisance tests 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 Environment at INFO@GDG.CA, or call, toll free: 1-877-227-0552.
Sept 8: The month of August has been fairly wet with over 100 mm of rainfall. Because of the intense amounts of rain received over a short period of time, streams overflowed their banks causing flooding of dry ponds and wetlands along the floodplain. This has generated a new generation of a flood water mosquitoes. Treatments were launched to control these mosquitoes, including use of their helicopter in the Kizell wetlands. They have been in the field treating from backpacks as well, but continuing showers have made it difficult to treat all areas where they breed so we have some problem areas. If you experience many mosquitoes please notify the contractor, GDG at firstname.lastname@example.org or call 1-877-227-0552 so they can investigate the cause and provide treatment in that area. Only larvae are treated so some mosquitoes will remain. Mosquito larvae can stay dormant for many years in dried up flood plains so information from the public is crucial to improving treatments in the future. The biological treatment program will end on September 19th this year and recommence next March.
Aug 16: Update from GDG Environnement – Mosquito treatment is presently ongoing in the Kanata area. Due to the accumulation of 64 to 89mm of rain during the weekend, larvae have appeared in most sites. Terrestrial treatment started on Monday, August 15th, and should be ongoing until Friday, August 19th. Aerial treatment around the Goulbourn Forced Road/Beaver pond will be done either Thursday or Friday. The helicopter will fly for less than an hour in that sector. Kanata_Aerial_Treatment_2016-08-17
July 5: Press Release G.D.G Canada, University of Ottawa and City of Ottawa collaborating on research on the effects of BTI treatments on non-biting midges in the South March Highlands.
July 4: Press Release by GDG Environnment re: Cattail Marsh Mosquitoes.
GDG Environnment confirmed that “a spring treatment was done in Kanata North for the Coquilletidia perturbans and field monitoring is continuously being performed for mosquito larvae developpement sites.”
May 17: The aerial application was completed this morning. The helicopter flew over Kanata a total of 2h45 between 8h and noon. No other aerial application is planned in the short term.
May 16: If there is no wind, the next aerial application in Kanata will be Tuesday the 17th of May on very specific areas of cattail marshes in South March park and Beaver pond area.
