The purpose of the Alamosa Mosquito Control District is to use ECONOMIC and ENVIRONMENTALLY responsible practices while suppressing the mosquito population. 
It is the mission of the Alamosa Mosquito Control District to protect the health and well-being of our public from disease and annoyance caused by mosquitoes while using environmentally sensitive practices.

*NOTICE*

 

 * The 2026 Operational Season has officially begun the week of April 13th. Larvicide surveillance only.​

​

*The week of May 18th - 22nd. You might see a Fog Truck spraying during the later afternoons and in short intermittent areas. The fog truck(s) WILL NOT be spraying any pesticide. We are training new drivers. Therefore, the sprayers will be omitting water only for training purposes.

​

* Fog Truck spraying will tentatively begin the week of May 25th. The abundance of adult mosquito activity and exceeding surveillance trap thresholds will determine the exact start date.

​

* AMCD will have new Larvicide and Fog Truck drivers this year. Please show patience and kindness as they are learning complex routes and your specific properties.
