The City of Monte Vista Public Work Department will begin its annual Mosquito Spraying operations beginning May 12, 2022 and will continue each Thursday evening through the middle of September.  The City does this to control the mosquito population and to protect the residents and visitors to our fine City from the diseases that mosquitos carry.

Residents can assist city mosquito control efforts by eliminating standing water within their yards and regularly changing water in things like pools and bird baths.  During our operations we use a combination of larvicides and adulticides.  Larvicides are used in public areas of standing water and the adulticides we apply are done through truck mounted aerial operations. These machines emit a fine spray into the air and we ask that during our operations that residents close windows and limit outside activities and please prevent your children from following the trucks.

This is a service that each resident of the City pays for an as such we spray all locations within the City Limits and also along Spruce and Pine off of Sherman. We also recognize that some residents may have an aversion to the chemicals we use; so for those residents we can also not directly spray your property frontage.  In order to be placed on what we call our  “Do Not Spray” list, residents must contact Robert Vance, Public Works Director at either 719-852-2692 or by email:

There are several factors that affect our operations, weather, wind and mosquito concentration. If conditions include rain or wind above 10 mph, these prevents us from continuing our spraying operations.  Due to the nature of our application methods we only spray on Thursdays so if the above mentioned conditions prevent us from spraying on Thursday we will not spray again until the following Thursday.  We do this in order for you to be able to plan your evenings knowing that we are out only one day, the same day, each week. In situations where the concentration of mosquitos become excessive we will add Tuesdays to our list but only until the concentration lessens.  If this occurs, it will be noticed on the radio and on City’s Website and Facebook pages.

In Summary:  Mosquito Spraying will begin on Thursday, May 12, 2022 and will run each Thursday through the middle of September.  Time:         Between the Hours of 8:00 p.m.—1:00 a.m.

Route: Thursdays—all of Monte Vista City Limits including Spruce and Pine off of Sherman
