WHAT IS LYME DISEASE? A. Lyme disease is a preventable bacterial infection transmitted to humans by the bite of the Western Black -legged tick, Ixodes pacili- cus. Lyme disease was named for Old Lyme Connecticut where it was first recognized. In 1978 the first cases were reported in California, and it has since become the most common tick-borne disease in California as well as in the United States. Q. WHAT CAUSES LYME DISEASE? A. Lyme disease is caused by a spiral -shaped bacterium (spirochete) identified in 1981, and named Borrelia burgdorferi. This bacterium mainly inhabits the digestive tract of deer ticks (Ixodes genus). The tick, acts as a "vector' transmitting the Lyme disease -bacterium to humans through its bite. Q. WHAT ARE TICKS? A. Ticks are tiny, insect-like creatures that can be found on grasses, brush and in wooded areas. They live by biting warm-blooded ani- mals inhabiting these areas and sucking their blood. The adult female has a scarlet fringe around her hind parts. The adult males are smaller and entirely brownish -black. The im- mature ticks are called larvae and nymphs. The larvae are slightly larger than the period at the end of this sentence. Q. WHAT ARE THE EARLY SIGNS AND SYMPTOMS OF LYME DISEASE? A. Within 30 days of infection, a characteristic bull's-eye rash may appear at the site of the tick bite. This is known as Erythema m Migrans (EM). It is usually accompanied by fatigue, headache, stiff neck, muscle aches and pains, and general malaise. About half of Lyme dis- ease patients never exhibit the classical EM rash. For such people the physician has greater difficulty making the correct diagnosis. Q. WHAT ARE THE ADVANCED SYMPTOMS OF LYME DISEASE? A. Possible complications may include chronic arthritis of one or more large joints, nervous system abnormalities and irregularities of heart rhythm. Q. DOES TREATMENT EXIST FOR LYME DISEASE? A. If treated early with antibiotics, Lyme disease can often be cured. Different antibiotic regi- mens are used against different stages. The treating physician is best equipped to make the choice of specific antibiotics. Early treatment shortens the course of Lyme disease and re- duces the frequency of late complications such as arthritis. It is most important, therefore, to diagnose Lyme disease and begin therapy as quickly as possible. Q. WHAT PREVENTATIVE MEASURES CAN AN INDIVIDUAL TAKE AGAINST LYME DISEASE? A. Some precautions can be taken to reduce exposure to tick bites. w- Wear light colored clothing so ticks can be seen and removed before they become at- tached to skin. or Wear long pants and long-sleeved clothing. tay- Tuck pants into socks or boots, and shirt into pants. r— Use approved repellents around shoes, an- kles and on exposed skin. Be sure to follow the label instructions! to- Choose wide trails and walk in the center. Avoid brushy and grassy areas and off -the -trail hikes. wThoroughly check yourself, your children and pets for ticks. 01 Rbducing rAH B colonies Homeowners should periodically inspect their property for potential AHB colonies.

CHIRONOMID MIDGE Characteristics • Cannot bite (no proboscis). • Develop in mud on bottoms of lakes and ponds. • Body longer than wings. • About same size as mosquito. CRANE FLY Characteristics • Cannot bite (proboscis, if present, unable to penetrate skin). • Develop in moist soil or water • Fly very poorly. • Usually larger than a mosquito FUNGUS GNAT Characteristics • Cannot bite (no proboscis). • Develop in fungus or moist decaying vegetation. • Have "spiny" legs. • About same size as mosquito. WHERE TO LOOK AND WHAT TO DO w Usable containers should be stored upside down. O ORNAMENTAL PONDS— Stock with mosquito fish. Add goldfish for looks if desired. O+ Avoid spraying with garden insect sprays. Remove leaves 0 and thin out pond lilies. Keep water level up. Screen inlet of recirculation pump. Chlorine kills fish—transfer fish to W glass bowl when cleaning pond. If pond is no longer desired, break holes in bottom and fill with dirt or sand. W CONCRETE OR PLASTIC SWIMMING POOLS — a Operate filter and skimmer everyday to remove egg rafts and larvae. Provide drainage for filter and pump sumps. Q Chlorine will NOT kill mosquito larvae. If pool cover is H used, keep it tightly sealed. Remove rainwater from top of Ems, pool cover. Stock unused or "out -of -order" pools with W mosquito fish. BOATS — ■ Prevent accumulation of bilge water. Store small boats upside down or cover to keep out the rain and water from q sprinklers. O ANIMAL WATER TROUGHS Stock large troughs with mosquito fish. Clean small troughs 3 every week. A OTHER KINDS OF CONTAINERS — Q Remove and dispose of all unused containers that will collect rain or water from sprinklers. a Cans Old Tires Jars Buckets W Barrels Tubs, etc. c� Home gardeners rooting plant cuttings in vases, buckets, W etc. should change water every week. Usable containers should be stored upside down. COMMON BACKYARD MOSQUITO BREEDING SOURCES ]� Neglected Swimming Pool Ornamental Pond MIDGES Chironomid Midge Chironomid midges cannot bite and are not harmful to public health. They can be a public nuisance because they develop in great numbers. They gather in swarms and when at rest they cover screen doors, windows, and walls. They look much like a mosquito and develop in the same water where mosquitoes develop. On a closer look, however, the midge: 1. Does not have biting mouthparts (proboscis). 2. Has a body (abdomen) that is longer than the wings. WE DO EVERYTHING WE CAN TO PREVENT THE DEVELOPMENT OF ADULT MIDGES Control of midge larvae is much more difficult than the control of mosquito larvae because the midge larvae live in the bottom mud and are much less vulnerable to our mosquito insecticides as well as to mosquitofish. Satisfactory control currently depends on continuing studies and research on new insecticide formulations and other possible control methods. MOSQUITO -BORNE DISEASE Several of the 48 known species of mosquitoes in California can carry disease under the right conditions. When a female mosquito takes an animal blood meal, which she uses as nourishment for her developing eggs, she may transmit certain disease causing organisms to humans and other animals. These organisms are taken with blood from infected humans and other animals. The mosquito completes the cycle when she bites the next susceptible host, causing infection. The two most important diseases affecting humans are encephalitis and malaria. ENCEPHALITIS There are two forms of viral encephalitis transmited by mosquitoes in California, St. Louis and Western Equine. Both are carried into an area by wild birds / that are infected elsewhere. These birds show no symptoms. Infected birds are then fed on by local mosquitoes that can pass the virus on to humans through future bites. Symptoms of encephalitis range from mild flu-like illness to severe brain involvement that can cause death. Western Equine Encephalitis can affect horses and other equine animals as well as humans. MALARIA Malaria is much less likely to occur in California due to the necessity for human reservoirs of the disease. Anopheles mosquitoes, the vectors of malaria, are found in some areas of California, and there have been isolated instances where human reservoirs from other countries temporarily provided asource ofmalaria infection to local residents. FISH PREVENT MOSQUITOES - Gambusia affinis, called "mosquito fish," are indispensable to our mosquito control program. They eat mosquito larvae as fast as they hatch from the eggs. Mosquito fish are furnished without charge for stocking ornamental ponds, unused or "out -of -order" swimming pools, and animal water troughs. They require no feeding and care is limited to protecting them from garden sprays and from chlorine or other chemicals used to clean the pond. We also stock thousands of these fish each year in artificial lakes, reservoirs, waste water disposal lagoons, natural creeks, and drainage channels to eliminate the need for frequent spraying with a mosquito insecticide. Gambusia affinis FACTS ON MOSQUITO FISH Mosquito fish do not lay eggs, but rather give birth to well developed and very active young. These fish, therefore, require no special environment, as most other fishes do, for depositing and hatching the eggs. They breed throughout the summer and new broods are produced at intervals of about six weeks, with 50 to 100 young in a single brood. The young are approximately 1/4 inch in length when born. They are ready to begin the work of destroying mosquito larvae at once. Gambusia grow rapidly, reaching a maximum size of about three inches. The earliest broods of the season, born in April and May, become sexually mature and produce young when six to eight weeks old. WHAT WE DO TO CONTROL MOSQUITOES OBJECTIVES The objectives of our program are to abate existing mosquito breeding sources and to prevent new ones in order to permit full use and enjoyment of our backyards and our many recreational facilities, to permit mosquito free agricultural and industrial working conditions, and to protect public health and comfort. PROPERTY OWNERS RESPONSIBILITY The owner of the property on which a breeding source is located is responsible for the abatement of the nuisance and for the prevention of its recurrence. We inform the property owner of the mosquito breeding and assist him in working out a satisfactory correction. In extreme cases, where the owner does not accept his responsibility to the public, the nuisance may be abated and a lien filed against the property as provided by the California State Health and Safety Code. BREEDING SOURCES WE CONTROL Chronic breeding sources created by standing water in street catch basins, subdivision drains, roadside ditches, flood channels, ravines, and similar places on public rights-of-way are controlled by routine larviciding operations throughout the year as necessary. We work with city, county, state, and federal agencies toward permanent correction of these sources.
