BATON ROUGE, LA (WAFB) - Millions of mosquitoes have emerged in Baton Rouge and across south Louisiana in the past few days, in large part due to the weather.

As a result, the East Baton Rouge Mosquito Abatement and Rodent Control center is preparing to send out
extra crews over the weekend to fight the swarm.

"I've been here for a little over three years and this is the worst I've seen," says Dr. Todd Walker, the director of the East Baton Rouge Mosquito Abatement and Rodent Control center.

The Mosquito Abatement team regularly sets up traps across East Baton Rouge parish. One located near the zoo usually traps a few mosquitoes over the course of the day. Between Thursday and Friday of last week, that same trap captured around two thousand.

The last time there were this many mosquitoes in the Baton Rouge area was back in 2006.

The reason for the surge is largely the weather. October 2015 was the wettest October on record in more than 100 years for Baton Rouge.

"We were essentially dry until October 23rd, and then 15 inches of rain came down in 8 days," says WAFB Meteorologist, Steve Caparotta.

During the dry spell, mosquitoes had a chance to lay tons of eggs. In a normal year with regular rainfall, mosquitoes would emerge in small bursts with each storm.

But this year was different. Without any rain, the eggs had a chance to accumulate.

"There's probably more eggs in these habitats than normal, so we created the perfect storm," says Walker.

Experts say this type of mosquito is more annoying than it is dangerous.

"The problem with them is that there's hordes of them, they like to feed during the day and they like your blood," says Walker.

mosquitoes of this proportion could be eliminated with low temperatures in the thirties and forties.

"That kind of cold we don't see coming anything soon," says Caparotta.

Walker of mosquito said they will be running extra shifts this weekend, spraying both on the roads and in the air.

A phone line at the mosquito abatement center is currently down. Those needing to reach out to the abatement center should instead email them at
