Mosquito Control activities, on a city-wide basis, seek to control insects in both immature larval and adult stages.

Residents are Asked to Assist in This Control By:

• Properly disposing of potential water holding containers such as old tires, cans and bottles.
• Not allowing boat covers, swimming pool covers, or toys such as wagons to accumulate water.
• Changing out water at least once a week in bird baths, ornamental pools, flower pots and children's wading pools

Information on Citrus Disease - "Huanglongbing" (HLB) (pronounced Wong-Long-Bing) is a devastating plant disease threatening citrus trees in Southern California, including the San Bernardino area where citrus trees are found in abundance on small farms and at homes.

Huanglongbing (HLB)

• Kills citrus trees
• No cure
• NOT harmful to humans or animals
• Has a latency period of 2 - 5 years
• If you think that your tree may be infected with HLB, you may simply call 800-491-1899. In response, a representative of the CDFA will return your call and ask a few questions to determine if your tree should be tested.
• If the CDFA believes that the tree may be infected, they will send out an inspector to take a sample from the tree for laboratory testing to see if it tests positive for the disease.
• If your tree is found to be infected with Huanglongbing (HLB), the CDFA will remove the tree at no cost.
