Between May 11 to Oct. 31, 2020, the Niagara Region is conducting a larviciding program in all 12 Niagara municipalities under the authority of the Medical Officer of Health. The program helps to control larval mosquitoes and prevent their development into carriers of West Nile Virus.
Storm drains are painted with a pink, green and blue dot to show it has been treated with larvicide.
In Port Colborne, the program schedule is as follows:
Round #1 (blue) – June 22, 2020
Round #2 (green) – July 24, 2020
Round #3 (pink) – Aug. 24, 2020
Additional treatments may take place, such as after periods of heavy rain.
The larvicide Altosid Pellets (PCP No. 21809, pellet), Mosquiron 0.12CRD (PCP No. 31079, ingot) or VectoLex WSP (PCP No. 28009, pouch) will be applied by direct hand application into municipal catch basins.
