Protecting Public Health in Your Communities
Colorado has a long history of environmental stewardship and awareness. Residents take pride in Colorado’s beauty and enjoy the outdoor activities and lifestyle in the state. VDCI’s Integrated Mosquito Management (IMM) Programs in Colorado continue these traditions of environmental responsibility by focusing on surveillance-based control strategies, public awareness, and the use of biological and “least-toxic” products. The VDCI team includes entomologists, mosquito control specialists, certified pesticide applicators, wetland scientists, and GIS specialists to meet all of your program needs.
Mosquito Surveillance Maps and Disease Testing Data in Your Community (select programs only)
Mosquitoes are more than just nuisance pests, they also pose a significant risk to public health by carrying and transmitting a number of debilitating and even deadly diseases. Mosquito-borne encephalitis in the U.S. is prevalent in several forms and is geographically wide-spread. In Colorado, Western Equine Encephalitis (WEE) and St. Louis Encephalitis (SLE) were the most common viral strains prior to the invasion of West Nile virus (WNV) in 2002. While West Nile virus is the most prevalent mosquito-borne disease in Colorado, and currently presents the greatest risk to human health, a growing concern for Colorado pet owners is dog heartworm, which can be fatal to both dogs and cats. Conducting regular adult mosquito surveillance and disease testing is a proactive approach to preventing and controlling vector-borne diseases in your community, and it is one of the foundations of VDCI’s Integrated Mosquito Management programs.

Adult Mosquito Control Spray Schedules
Spraying Will Occur Between Sunset and Sunrise, Weather Permitting
As West Nile virus has become established across the U.S., and other mosquito-borne diseases continue to surface, there is an increasing need for proactive control of the mosquitoes that transmit these diseases to humans, birds, horses, and other animals. Our team focuses on unique and innovative ways to protect public health from mosquito-borne diseases, while preserving the environment, and minimizing program costs. Adult mosquito control spraying is only conducted when necessary and after designated thresholds are met. When the need for adult mosquito control occurs, all the products utilized by our team are EPA and Colorado state approved for public health applications.
Spray events may be cancelled or postponed, all or in part, without notice. Notice of rescheduled spray events will be posted on VDCI’s spray schedule.

Targeted Mosquito Control Efforts in Your Community
(select programs only)
Through the use of modern technology, equipment and insecticides, effective control of adult mosquitoes is possible. Ultra-low volume (ULV) spray technology is the key to this success, whereby an extremely small amount of insecticide is applied over a very large area, thus controlling adult mosquitoes while not adversely affecting local residents, wildlife, or the environment. With accurate timing and precise application, a kill rate of over 90% of the adult mosquito population within the target area can be achieved. A truck or ATV-mounted ULV spray machine is used to produce extremely small (< 20 micron diameter) droplets of the chosen insecticide, which is dispersed within the target area. In order to maximize the effectiveness on adult mosquitoes, while minimizing exposure to non-target species, applications are timed to coincide with the non-activity period of beneficial insects such as bees and butterflies, and with the peak activity period of mosquitoes, which is from sunset through the early morning hours.

Putting pesticide residues in perspective
There are a lot of misconceptions about the amount of pesticides that are used in the environment. Pesticides are usually applied at an application rate of 1 pound per acre or some fraction of a pound per acre which would mean that one teaspoon of sugar spread evenly over 5,000 5-inch cereal bowls is an application rate of 1 pound per acre. Environmental Protection Agency (EPA) products are widely utilized in many mosquito abatement programs across the country because of their efficacy and minimal environmental impacts. VDCI carefully selects these products with the goal of protecting both people and the natural environment while economically reducing nuisance and disease-vector mosquitoes to tolerable levels.
What you need to know about truck spraying
VDCI utilizes surveillance to track mosquito populations to learn where viruses, like Zika or West Nile, may be present or spreading in a community. Spraying insecticides from a truck is an important component of an Integrated Mosquito Management program used to control mosquitoes, especially when mosquito levels reach dangerous thresholds or disease is identified in a given area. VDCI uses only EPA-registered products and relies on data to ensure we are spraying the right amount of product in the right area at the right time.
