WNV Program |
| Under certain circumstances,
mosquitoes and biting flies can reach levels where they make any outdoor
activity virtually intolerable. These conditions can make it impossible
to enjoy a backyard barbeque, outdoor gathering or other outside activity.
Businesses relying on patrons in an out-of-doors setting (golf courses,
campgrounds, etc.) can see revenues drop dramatically when mosquitoes
or biting flies reach intolerable levels. These circumstances deserve a professional, environmentally sensitive nuisance management program such as that offered by Morrow BioScience Ltd. Morrow provides nuisance management programs tailored to their clients’ individual requirements and in accordance with the principles of integrated pest management. Morrow’s philosophy is to use consultation, education, prevention and monitoring as well as treatments to control pest population. Public consultation and education is achieved through holding ‘town hall’ meetings, operation of mosquito ‘hotlines’, advertising in local newspapers, operation of the Morrow website and other means. The objective is to inform and involve members of the public in matters related to mosquito characteristics, WNV issues, annoyance prevention, elimination of rearing sites around the home and program activities. Control of mosquitoes is most effective when they are in the larval stage. For this reason, most of the efforts are placed on finding larval development sites, reducing their viability or treating them when larvae are found in sufficient numbers. During the spring and summer, technicians locate and map new potential development sites using a GPS (Global Positioning System). All sites are added to a database, which are incorporated into a GIS (Geographic Information System). Known development sites are monitored by technicians for the presence of mosquito larvae at least once every week or two. If sufficient larvae are found in the development sites, they are then treated using a biological mosquito larvicide, Aquabac. If no larvae are found in the development sites, no treatment occurs. |

| The Mosquito GIS
can be referenced at any time to show relevant data for a particular
site such as: |
|
 |
Development site size and exact location |
|
Historical results from monitoring (ie; number of larvae present |
|
Treatment dates and details |
Or general information such as: |
|
|
Municipal, City or other boundaries |
|
Areas not to be entered for a particular reason |
|
River levels or climactic data |
A reduction of annoyance levels by 80% or more can easily be achieved through implementation of the Morrow BioScience Ltd. nuisance management program. |
