Simon Wilkins, the city's Integrated Pest Management Coordinator, said that this damp weather conditions, coalesced with scorching hot summer sun, will generate ideal conditions for the vicious bugs to boom.

Wilkins said that it's not as if there's a calamity in the near future, but they are anticipating a regular level of mosquitoes, this year.

He observed that the last two summer seasons have been nearly free of mosquitoes owing to dry conditions. The insects require a soggy breeding environment along with warmth to grow.

Wilkins said that eggs can lie inactive in soil for many years.

He said, "That's what happened in the 2005 flood. Areas of the city got hit with water that normally don't have water and then all the eggs hatched and it led to a higher number of mosquitoes in 2005 and 2006".

There are some mosquitoes in the region of Calgary at the moment, but they are missing out on an important element: sunlight.

Wilkins said that they are out there in the cold and wind, and gradually growing. If the climate becomes a little temperate, people will notice them.

Water and heat combine to make an ideal home for the breeding of the mosquitoes.
