Integrated Vector Management (IVM) is an effective and environmentally sensitive approach to vector management that relies on a combination of common-sense practices. The District's IVM program uses current, comprehensive information on the life cycles of vectors and their interaction with the environment. This information, in combination with available vector control methods, is used to manage vector nuisance and public health threats by the most economical means, and with the least possible hazard to people, property, and the environment.
Butte County Mosquito and Vector Control District's IVM includes vector surveillance, source reduction and/or elimination, public education, biological control, and chemical control.

The District utilizes an extensive surveillance program for both adult and immature (larval) mosquitoes. Throughout Butte County the District uses 26 New Jersey light traps, 20 gravid traps, 7 sentinel chicken flocks, and over 40 CO2 traps to monitor adult mosquito abundance and virus activity. District Mosquito Control Specialists monitor larval mosquito populations throughout the entire county on a daily basis utilizing a standard one-pint dipper. District Mosquito Control Specialists spend the majority of their daily routine inspecting standing water such as rice, wetlands, storm drains, ponds, ditches, swimming pools, bird baths, fountains and other man made containers for larvae.
The District utilizes an entomology department (Lab) that is staffed with an entomologist and a lab technician. The District's entomology department is responsible for the identification of the trapped mosquito collections and reporting the population numbers to the California Department of Public Health. The lab conducts virus testing on live mosquitoes, dead wild birds, and sentinel chicken flocks. These tests are the Districts eyes to monitor and detect mosquito-borne viruses in and around the county. The lab also conducts scientific pesticide trials to monitor the chemicals effectiveness on targeted mosquitoes and to assess the possible effects of non-targets and trials on new chemical methodology and/or new chemicals. The lab is also at your service to identify ticks, arachnids, and other insects.
Source Reduction and/or Elimination
Butte County Mosquito and Vector Control District continually evaluates new and old biological control methods and products. The District continually sends staff to advanced training and seminars to retrieve new technology and ideas from around the world to maintain that the District remains on the cutting edge of science.
While the mosquito larvae is confined to the water, it can be eliminated before it is able to emerge. If a target pest can be treated before it becomes mobile, the area requiring treatment will be much smaller. District Mosquito Control Specialist identify sources of water that are producing mosquito larvae and assess if the source can be eliminated, re-designed or re-managed to prevent future breeding, and evaluate if biological control measures will be effective. If these options are not practical for the source then the specialist will conduct chemical control (larvicide) to eliminate the targeted mosquito larvae. Chemical options include some materials that are targeted to affect only a few insect species, leaving predatory and other insect and non-insect aquatic species unharmed. All products are registered with the California Environmental Protection Agency (EPA) and are applied by trained and state-certified specialists.
As part of the integrated vector management program, the District may administer Ultra Low Volume (ULV) treatments by using backpack foggers, hand sprayers, all terrain vehicle mounted foggers, truck-mounted foggers or aircraft, in and around areas where virus activity has been detected. Each fogging unit's output is calibrated to ensure the correct amount of product is applied for each treatment area. All products are registered with the California Environmental Protection Agency (EPA) and are applied by trained and state-certified technicians. Adulticides are chemicals that quickly reduce adult mosquito populations. Larvicides target immature mosquitoes.
The District will make every attempt to notify individuals who sign-up for the District's email notification list. However, the District may not be able to notify the public if immediate applications are needed to protect public health and welfare from diseases such as West Nile virus, western equine encephalomyelitis, St. Louis encephalitis, malaria and future newly introduced viruses. The District may also cancel a scheduled operation due to un-favorable weather conditions and/or other reasons.
