Larviciding in 2005

Catch Basin Larviciding Program

During the 2005 season, a total of 147,630 catch basins were treated with methoprene (PDF). These treatments were conducted in mid-June, mid-July and mid-August.

Surface Water Larviciding Program

A total of 50 surface water sites (identified as larval mosquito breeding sites), were treated with Bti (Bacillus thuringiensis israelensis) (PDF). Some of these larval mosquito breeding sites were treated more than once, resulting in a total of 316 surface water treatments with Bti during the 2005 season.
