WHAT TO DO: If you live in one of the many mos- quito abatement districts in California, report any undue numbers of mosquitoes to the district office, which has trained personnel and equipment for locating and treating the source of breeding. Other agencies from which advice may be obtained include the Entomology and Parasitology Department of the Univer- sity of California, local farm advisors, and local and state health departments. Control. For immediate control in- doors, close infested rooms and mist- spray the air with a kerosene solution containing knockdown agents such as pyrethrins, or Lethane 334 plus killing agents such as DDT. You can also use aerosol bombs which emit the insecticide in the form of a mist. Such sprays or aerosols kill only mosquitoes present in the room at the time of treatment. For a residual spray, use a 5 per cent solution of DDT in refined white kero- sene. Apply this directly to all the inner walls of the house and to the underside of tables and other furniture. Apply as a coarse spray in sufficient amount to wet the surface but without runoff of excess liquid. DDT and methoxychlor are the only materials recommended for widespread use as residual sprays against mosquitoes in the home; of these DDT is preferable. Such sprays are inflammable; see page 6 for precautions. Residual sprays may be applied out- side the home on walls and ceilings of porches, on door screens, around doors and windows, on foundations of build- ings, on tree trunks, and in outbuildings.
