Prevention

The District provides as guidelines, mosquito prevention criteria that was endorsed by the California Department of Health Services and the San Francisco Bay Conservation and Development Commission in 1978 as part of the Suisun Marsh Protection Plan under California State Assembly Bill 1717.

Criteria For Mosquito Prevention Below.

May contain: water, nature, outdoors, and land

Drainageway Construction and Maintenance Practices

Mosquitoes breed in creeks and ditches where ponding occurs due to obstructions, overflow of banks, excessive siltation and back-eddys created from low water flow during the dry months. Consequently, modification of drainageways (digging, and filling, etc.) is often necessary to allow free flow of water. Construction of new ditches must be undertaken to maintain adequate circulation of water.

Dredge Material Disposal Sites

In many instances, land disposal of dredge material creates mosquito-breeding sources. Due to the initial high water content and characteristics of the dredged material, shrinkage cracks occur in the drying process. These shrinkage cracks provide ideal habitat for the production of mosquitoes. Experience by mosquito abatement agencies has shown the use of chemicals to kill mosquito larvae in the…

Household and Residential Areas

A number of types of sources found within residential neighborhoods are capable of producing enough adult mosquitoes to bother not only the residents of the home, but a number of homes in the area. Water left standing for seven to ten days can produce mosquitoes during warmer weather. There are a number of simple precautions that can be taken to prevent this from happening.

Irrigated Pastures

Those irrigation practices which are advantageous to mosquito control are also beneficial to the production of crops. At least 3 days in water are required for mosquitoes to reach the adult stage. With the exception of rice, water which is left standing for more than 24 hours after irrigation is of no benefit to the field in which it remains and usually becomes detrimental to the crop. In most…

Permanent Ponds Used as Waterfowl Habitat

The diversity of waterfowl habitat in the Suisun Marsh is increased by the occurrence of permanent ponds. Permanent ponds, however, should remain a minor part of the marsh habitat because (1) they require specific conditions to provide optimum habitat and (2) other more intensive types of management can generally be carried out that provide for higher yields of waterfowl food.

Salt Marsh Restoration of Exterior Levee Lands

These lands were originally tidal marshes, vegetated areas subject to daily tidal action. They were reclaimed for agricultural and other uses by the construction of levees and the installation of one or more water control structures to control the inflow and outflow of water. The Suisun Marsh Protection Plan recommends the restoration of former tidal marshes to tidal action where and when possible…

Sedimentation Ponds and Retention Basins

Sediment basins, sediment traps, diversions or similar required measures shall be installed well in advance of any clearing or grading and maintained by the permit-issuing authority. The design of such structures should account for abating potential mosquito problems.*

Tidal Marshes

Historically, tidal marshes in Solano County were prolific sources of mosquitoes, an aggressive, migrating, day-biting species. In addition to direct abatement, water management practices have been developed by the Solano County Mosquito Abatement District (SCMAD) to prevent the production of mosquitoes in tidal marshes. The principal prevention method consists of the construction of ditches to…

Utility Construction Practices

Installation of natural gas lines and wells, electrical lines, telephone lines, petroleum pipelines and the like can alter both topography and habitat. Activities which disrupt drainage patterns, obstruct water flow or water control structures, prevent access, or leave mounded debris can cause mosquito production.
