As a resident of Sacramento or Yolo county you are entitled to mosquito and vector control provided by the District at no charge. Please fill-out the form below if you would like a visit from one of our field technicians or to report a potential mosquito breeding source.

See below for more details about our services pertaining to: Mosquitoes, Mosquitofish, Yellowjackets, and general Information.

Mosquitoes - If you believe that you are having a problem with mosquitoes in your area, first ask yourself, "Am I being bitten?" There are many species of insects that are often mistaken for mosquitoes, but are in fact quite harmless. You know you have a real mosquito problem if you are being bitten.

Once you have concluded that you have mosquitoes, we ask that you attempt to obtain a sample mosquito. This can be done by gently swatting or clapping a live mosquito, and placing the stunned or killed specimen in a small plastic bag. This will help our field technicians to identify the species and determine the most effective treatment for that particular type of mosquito. For example, some species breed primariliy in small isolated bodies of standing water, while other species are found almost exclusively in water-saturated treeholes.

Mosquitofish - Often the best treatment for mosquitoes is to place small fish that feed upon mosquito larvae into the standing water in which the larvae live. The most common fish used to accomplish this is the Mosquitofish, also known as Gambusia affinis. Threespined-Stickleback (Gasterosteus aculeatus), and the tropical guppy are also used for this purpose.

The District raises these fish at its facility and provides them to District residents at no charge, providing there is a need. The fish are available for delivery only (no pick-ups). The amount needed will be determined by the technician, who will then plant the fish in the identified water source.

Yellowjackets and wasps - If you have located a nest or hive of these vectors, the District is available to help. Depending on the circumstances, technicians will attempt to spray, destroy, or relocate these nests. Nests are often found in the ground, trees, walls of homes, or under eaves of a roof. Understand that if the nest has penetrated into the structure of your home or building, the District cannot treat it. Additionally, we will not be able to treat the upper-levels of multi-story buildings. At that point it will be necessary to hire a private Pest Control Agency to come and take action.

Information - The District is always available to provide information pertaining to a large number of pests and vectors. Besides the vectors we actively pursue and treat (such as mosquitoes and yellowjackets), we are available to offer information and advice on ticks, spiders, rats, gnats, flies, etc. We also offer information on diseases passed by these animals.
