GOOD MORNING,
YOU HAVE TO LOVE THE RAIN AND COOLER WEATHER. THIS WEEK LOOKS TO BE A DIFFICULT ONE FOR BC MOSQUITO WITH THE FORCAST OF WIND, COOL TEMPS, AND RAIN. WE WILL BE FOGGING WHENEVER THE WEATHER PERMITS US.

PLEASE TAKE PRECAUTIONS WHEN OUTSIDE, THIS IS THE TIME OF YEAR THAT WEST NILE BECOMES MORE OF A CONCERN. THERE HAS BEEN A POSITIVE FINDING OF WEST NILE IN ONE POOL IN BLAINE COUNTY. THERE HAS ALSO BEEN A POSITIVE IN A HUMAN IN CASCADE COUNTY. PLEASE DO WHAT YOU CAN TO PROTECT YOURSELF.

Do you know the species that are leaving their mark in Teton County? 🦟 ⛰️

💥 While Teton County is home to dozens of different mosquito species, the two primary nuisance species that bite humans are Aedes vexans and Aedes dorsalis.

Culex tarsalis, the Western encephalitis mosquito and the species that vectors West Nile virus (WNV), is the District's top-priority mosquito. However, it is significantly less abundant in Teton County than the other major nuisance species.

Good evening Paradise Valley. I planned on fogging your area tonight, however to my dismay we have two fogger pickups giving us problems. Hoping to have them fixed tonight, hopefully. If I can get one of them operational I will fog late late tonight or early tomorrow morning. I APPOLOGIZE. I WILL GET YOU COVRRED AS SOON AS POSSIBLE

Good Morning Blaine County

As you all can tell the mosquitoes have hatched and are in attack mode for sure. We have all our foggers out working when the weather allows. This past two weeks have been very difficult with weather but we are doing everything we can to gain control. I will have weekly updates on our progress. Please remember wind and temperature are the main factors we must work around. We cannot fog during the day, so our time frame is evenings and early mornings. I will be posting throughout the season on helpful tips on reducing mosquito population and pressure around your house and yard. We will probably see a couple of weeks of high population until things stabilize. Please check this page for info and updates on fogging progress.

THANK YOU
