A bumper crop of mosquitoes in the area is raising concerns for local health officials as they try and combat the West Nile virus.

"We're looking for mosquito so if we find more than seven in here, we'd apply the larvicide," says Jeremy Hogeveen, vector-born disease coordinator with the Middlesex-London Health Unit, while inside a London woodlot.

2012 was the worst for the virus in Ontario since 2002 because it was so hot and humid.

Hogeveen says it's too early to know how bad 2013 will be but he is finding more adult mosquitoes.

"We are looking at more due to the amount of snow we had this winter and the extra precipitation we had this spring," he says.

Hogeveen says its not just wooded areas where people should take precautions, residents should examine their own backyards.

"Remove standing water...and report dead crows and blue jays," says Hogeveen.

Residents should aslo protect themselves by wearing insect repellant with DEET and wearing long sleeves and long pants.

If infected, symptoms can range from fever and headache to, in the worse case scenario, death.

Last year a Windsor-Essex man died and in 2011 the virus claimed the life of someone in London.
