CANYON COUNTY MOSQUITO ABATEMENT DISTRICT MOSQUITO MANAGEMENT PLAN FOR 2011 Submitted to the Canyon County Board of Commissioners: Idaho Code, Title 39 Health and Safety chapter 39-2804 paragraph 9. Authority: Idaho Code Title 39 Health and Safety. 39-2801A. Authorization to form abatement districts. There may be formed, under the provisions of this chapter, districts for the abatement of mosquitoes or other vermin of public health and welfare importance, in any area of the state from territory of one (1) or more counties, one (1) or more cities or towns, or any combination or portion thereof…… MISSION GOAL The mission goal is to help protect the citizens that live within the CCMAD boundaries from disease carrying mosquitoes such as the Culex species, which is the primary vector for the West Nile Virus. The second part of CCMAD mission is to improve the quality of life for District constituents by managing mosquito populations to prevent a nuisance and or economic loss to areas of the district. The third part of CCMAD mission is to help protect District animal and livestock populations from mosquito borne disease or parasites. CCMAD operates on Integrated Pest Management principles (I.P.M.) using precision targeting methods that are tied to a pesticide reduction effort. This I.P.M. approach translates into a sustainable method of managing mosquito populations that combine biological, cultural, physical and chemical tools in a way that will minimize economic, health and environmental risks. This approach relies on extensive monitoring to aid in predicting potential insect and disease outbreaks, thus allowing intervention methods to be preventative rather than reactive. 1 INTRODUCTION The Mosquito Management for 2011 also is designed to meet the requirements of Pesticide General Permit (PGP) for the Point Source Discharges to the Waters of the United States from the Application of Pesticides: The Canyon County Mosquito Abatement District jurisdiction encompasses the geographic borders of Canyon County Idaho: Canyon County Idaho: 589 Square Miles Population: 186,600 Canyon County Mosquito Abatement District Jurisdiction Boundaries 2 Canyon County Mosquito Abatement District Control Sectors: CCMAD is divided into the following control sectors for control and mosquito population surveillance purposes. • Lake Lowell Sectors: This constitutes areas around the south side, east side and north side of Lake Lowell adjacent to the Deer Flat National Wildlife Refuge.

I.P.M/I.M.M. principles are as outlined in the American Mosquito Control Association (AMC) document “Best Management Practices for Integrated Mosquito Management, December 2, 2009. Integrated Pest Management/Mosquito Management is a comprehensive pest strategy that utilizes all available mosquito control methods singly or in combination to exploit the known vulnerabilities for mosquitoes in order to reduce their numbers to tolerable levels while maintaining a quality environment. Integrated mosquito management methods are specifically tailored to safely counter each stage of the mosquito life cycle. Larval control utilizing natural biological control methods, sanitation practices, and water or vegetation management methods or other types of source reduction measures where compatible with the other land management uses, are prudent mosquito management alternatives-as is use of EPA-registered larvicides and adulticides. When source elimination or larval control measures are not feasible or are clearly inadequate, or when faced with imminent mosquito/insect-born disease, application of adult mosquito control products are chosen based upon their demonstrated efficacy against species targeted for control, resistance management concerns and minimization of potential environmental impact. (from AMCA Best Management Practices for Integrated Mosquito Management) Integrated Mosquito Management/Pest Management program activities goals will strive towards the wise use and reduced use of pesticides. IPM/IMM is a decision making process that uses all available pest management strategies. This process will help determine what method of control will reduce the mosquito populations to an acceptable level. The Canyon County Mosquito Abatement District’s IPM/IMM methods will take into account the potential health risk to an arbovirus threat to determine the most effective abatement strategy. 8 The Canyon County Mosquito Abatement District Integrated Pest Management/Mosquito Management program is knowledge base and surveillance driven and is designed to accomplish the following: • Protect human, animal and environmental health. • Promote a rational use of pesticides. • Reduce environmental contamination to soil, ground water, bee pollinators, wildlife and endangered species. • Encourage the use of natural biological controls to augment other control methods. • Use target specific pesticides to the extent possible. • Proper timing of pesticide applications. • Minimize resistance CCMAD IPM/IMM will identify the following strategies for the management of mosquito populations: • Education: This is the first strategy and in many cases the most effective. When constituents are trained to recognize, report or remove potential mosquito production sites on their property or other property, it makes the job of CCMAD easier. Education can be done very economically and has a direct impact on mosquito populations. Examples of CCMAD education efforts and programs are the following: 1. Distribution of CCMAD neighborhood flyer “Take the Bite Out of Summer, a Guide to Backyard Mosquito Control”. 2. CCMAD Webpage: canyoncountymosquito.com which is updated weekly or more frequently during the mosquito season. 3. CCMAD is an active source for news articles in local newspaper and TV/Radio features. 4. CCMAD participates in community functions such as the annual Deer Flat National Wildlife Refuge “BioBlitz”. • Cultural: This strategy is tied very closely to education and involves behavior changes to avoid mosquito bites such as: 1. Where long sleeved shirts and long pants during peak mosquito activity. 2. Limit outdoor activity during mosquito peak activity or change time of day of outdoor activity. 3. Be aware of irrigation practices and practice good water management 4. Wear mosquito repellant when outside during peak mosquito activity. • Mechanical: These strategies involve the actual habitat manipulation of mosquito production sites “source reduction” and harborage for adult mosquito resting sites. Examples of Mechanical strategies are: 1. Cleaning house gutters. 2. Emptying bird baths and making sure boat covers, swimming pool covers are free of standing water. 9 3. Keeping weeds and excess vegetation levels down; mowing ditch banks and vacant lots; proper pruning of shrubs and trees. (eliminate harborage areas). 4. Actual source reduction, and standing water, chronic wet area drainage. Note: The main source of mosquito population in the Canyon County Mosquito Abatement District is Deer Flat National Wildlife Refuge and the Boise River corridor from the Ada County line to the confluence of the Snake River west of Parma, Idaho. Water levels for these two sources are dictated by snow run off and regulated by the Bureau of Reclamation-Boise Project Board of Control. Source reduction is either seasonal or as managed by this agency. • Biological: Biological control is the introduction predators to help control mosquito populations. Mosquito larvae eating fish such as Gambusia, blue gills or minnows are all sources of mosquito eating predators that may be introduced to permanent water bodies. Other mosquito predators are dragonfly larvae and bats for adult mosquitoes. Biological control efforts are very intensive and not efficient efforts to control mosquitoes on a large scale but can be utilized on a specific site. Gambusia “Mosquito Fish” Bat House • Chemical or Pesticide Use: This strategy is divided into two main categories: 1. Larvae Control: Larvicide applications are the main key to sustainable mosquito population management and is the primary effort of the Canyon County Mosquito Abatement District. Studies have shown that 1 acre of mosquito larvae control operations can prevent up to 100 acres of adult control measures such as “neighborhood fogging.” The pesticides that CCMAD use for larvae control are very targeted and specific with little or low impact on the environment or non targeted arthropod species. Larvicide operations re either conducted by ground crews or by aircraft. 2. Adult Mosquito Control: This is the most high profile of all mosquito abatement activities and is used when conditions warrant, such as the presence of a disease threat, elevated population levels of disease vector species or high levels of other mosquito species that may pose a quality 1 0
