Larviciding in 2008

Catch Basin Larviciding
Regionally and municipally-owned roadside catch basins throughout the Region are monitored for larval mosquito activity beginning in June. Three catch basin treatments are conducted during the 2008 WNV season with the first treatment occurring in mid-June. Subsequent treatments occurred in July and August.

A total of 164,716 roadside catch basins and approximately 250 catch basins located on Regional properties were larvicided.

Surface Water Larviciding
In mid-May, areas of standing, stagnant water were assessed as larval mosquito development sites. Where remediation of identified larval mosquito development sites was not possible, a biological larvicide was applied following a local risk assessment.

In 2008, a total of 210 sites were monitored with 91 sites requiring treatment with a larvicide.
