You might have a lot of uninvited company as you try to enjoy the long weekend

They could be here early and in overwhelming numbers.

Mosquito experts are bracing for a severe summer of airborne blood-suckers after a mild winter and a soaking-wet start to spring has led to ideal conditions for the insects to multiply.

"If the weather continues to trend warmer, there are going to be a lot of mosquitoes breeding very quickly," says Daniel Mackie of GreenLeaf pest control, who adds he's already getting calls from clients with concerns about the bugs.

He says standing water in catch basins, ditches, and eaves troughs present perfect places for populations to explode.

Not only are mosquitoes a nuisance, but they can also pose significant health risks.

West Nile Virus is spread mostly through mosquito bites and that has public health authorities monitoring the situation closely.

Crews will head out in the weeks to come to clear standing water from city property, and spray for mosquito larvae.

Mackie says one way to keep the pests out of your way while you're trying to enjoy the warm weather is to make an addition to your patio or balcony.

He says a good-quality outdoor fan will help keep mosquitoes at bay simply by making the surrounding air too difficult to pass through.

"Air currents make a big difference," Mackie says, "insect manage insect a food plant is the same:  if they can't fly and if they can't get to you, they won't be able to bite you."
