Buzz, slap, itch, scratch - repeat.

The mosquito invasion is in full force, and if you think this year鈥檚 blood sucker is extra aggressive 鈥� you are correct, says mosquito expert Michael Jackson, president of Culex Environmental.

Culex Environmental does mosquito control for the Metro Vancouver region.

It has more than 5,000 locations throughout Metro Vancouver, where it monitors and works to prevent mosquitoes from hatching.

The recent heat wave that brought record temperatures into the 30s between June 23-25, created the perfect conditions for adult mosquitoes to invade.

鈥淭he mosquitoes were delayed for sure, but with that heat wave it created the perfect storm. The flood water came up and then the heat wave arrived,鈥� Jackson said.

Even the name of this mosquito sounds intimidating. The aggressive mosquito sucking your blood is called Aedes Sticticus.

鈥淭he adult Aedes Sticticus have migrated into the area. They are going to be around for a week or 10 days more, unfortunately.鈥�

Culex carried out another treatment of area hot spots in an attempt to stop any new larvae from hatching.

鈥淲e鈥檝e done everything we can do. We can say it would have been a lot worse if we hadn鈥檛 done the treatments we did.鈥�

In 91原创, Brae island is a hot spot for larvae, so Culex has applied several larvicide treatments.

Most parts of 91原创 are experiencing the buzzing nuisance insect, from Fort 91原创 to Walnut Grove.

Granular bacterial larvicide is dropped into the water from a hovering helicopter. The larvicide does not harm other insects,amphibians, reptiles, fish, birds or mammals, said Jackson.

鈥淎rial granulation is not spraying, I just want that to be clear. We drop the granules and they work really well to kill the larvae.鈥�

So how to get through this long weekend and still be outdoors?

Two repellents do work. DEET works but users must follow the instructions properly. The other repellent is Picaridin, which works just as well, but is more natural.

At dawn and dusk wear long sleeves, pants if you can.

The 91原创 Times interviewed Jackson on June 19 and put out a story explaining the delay of the pesky insects.

Since then, he said he has been busy with calls from people who have are itching and scratching.
