I bet everyone is relieved that winter is finally over. However, with warmer temperatures come the mosquitoes…
My team and I are receiving a lot of questions about the Kanata North Nuisance Mosquito Control Program. Hence, I’d like to take this opportunity to provide an update and to answer some of the questions that have come up.
We are now entering the fourth year of this program (2016 to 2019), which is conducted by GDG Environnement. The team monitors and enters wetlands in and around Kanata North to find mosquito larva and to subsequently treat them with natural protein bacteria in order to prevent the larva from hatching into live mosquitoes.
Larva surveillance has started, and GDG Environnement reported that first instar larvae has been found in our wetlands. As a result, ground treatment (nozzle-sprayed bacteria using backpacks) and aerial treatment (by helicopter or airplane) has begun.
What exactly is being sprayed? The control agents that are used for both ground and aerial application are:
- Bacillus Thuringiensis Israelensis (Bti): VectoBac 1200L (registration #21062) and VectoBac 200G (registration #18158)
- Bacillus Spaericus (Bs): VectoLex CG (registration #280008)
In order to successfully implement the program, GDG Environnement will require access to wetlands within the designated treatment area (see below map). The treatment area includes the entire Kanata North Ward as well as a 2 km perimeter surrounding the Ward.
Objection request letters were sent this past February to residents with properties located within the Kanata North Nuisance Mosquito Control Program treatment area, asking affected residents if they objected to GDG Environment accessing their property for the application of larvicide. A copy of this letter can be found here.
I’m sharing the City of Ottawa FAQs with more details. Further information can also be found online.
