The board of trustees for the Orange County Mosquito and Vector Control District voted on April 21 to deny the district manager the ability to initiate spraying of mosquito areas suspected to foster West Nile Virus. The board could, however, revisit the issue at next month’s meeting.
The district is likely to bring forth a resolution that would require a board vote to implement aerial spraying of mosquitoes, according to Jim Dahl, the San Clemente representative on the board.

The district does not do any aerial spraying at this time. Last year, the board wanted to start the process of aerial spraying but couldn’t get airspace clearance from Disneyland or approval from the Federal Aviation Administration.

Citizens at the San Clemente City Council meeting on April 19 spoke against the use of spraying by aircraft, as the pesticides would cause harm to local insects essential to the ecosystem as well as human health.

The spray the district would use is Duet, which some have criticized as having harmful components.

The next MVCD meeting will be Thursday, May 19. More information about the policy can be found at www.ocvcd.org.

  • Please sign and share the petition to have this aerial spray of poison on our homes and schools stopped.

    Duet – what OCVCD has proposed to be sprayed on our homes yards schools etc has three active ingredients: Sumithrin, Prallethrin, and Piperonyl Butoxide (PBO). (I have attached the insert sheet for Duet for you as well) I have included many studies below

    Pediatric Cancer and Pesticides

    Sumithrin, is also called phenothrin, is a synthetic pyrethroid. Prallethrin is also a synthetic pyrethroid. As pyrethroids, sumethrin and prallethrin cause nerve paralysis in the insect, effectively shutting down the insect’s functioning.

    Sumethrin is a known endocrine disruptor, neurotoxin, and likely carcinogen. In 2005, the Environmental Protection Agency (EPA) revoked permission to use sumethrin in flea and tick products after thousands of cats and kittens were poisoned and killed by its use. Few long-term studies on the safety of pyrethroid insecticides exist because they have only been in widespread use since after 2000 when the EPA phased out the use of chlorpyrifos and other organophosphorus insecticides due to risks to child neurodevelopment.

    Pyrethroid chemicals Sumithrin, Prallethrin contained in the DUET product are classed as “neuropoisons” by the World Health Organization.

    These pyrethroids have a demonstrated association with cancerous tumors in mammals, and ongoing exposure has been linked to blood biochemical changes in humans.

    One of the *non-insecticide* ingredients in the Duet product, Piperonyl Butoxide (PBO), is incredibly toxic. PBO also can persist for weeks before breaking down in the environment under certain conditions.

    Piperonyl butoxide (PBO) is especially harmful to the developing fetal brain. A 2011 study, conducted at Columbia University and published in the Journal Pediatrics, found that infants whose mothers had been exposed to low levels of piperonyl butoxide (PBO) during their third trimester showed delayed mental development by the age of three.

    A more recent study by Duke University study confirmed these findings and found that the chemical also interferes with signaling in the human brain. The Duke study, which was published in the journal Toxicological Sciences, found that PBO’s disruption of the critical neurological pathway “may be the molecular basis for profound developmental defects in children exposed in utero to PBO.”

    They are extremely toxic to bees and fish, and have been identified as a contributing cause to the worldwide ecological catastrophe of Colony Collapse Disorder – many studies on Sumithrin regarding this (did not include).

    Research continues, and truly comprehensive study of what the long-term negative effects are of this type of blanket spraying of toxins into the environment has not yet been undertaken, but the existing data clearly demonstrates a clear and significant risk factor for human beings and overall environmental health. In short, given the information provided, there simply is no rational, scientifically justifiable way that you can approve the taxpayer-funded poisoning of our homes, parks, schools, yards churches air and water ways, in light of the absence of any conclusive evidence that it produces any desirable effect whatsoever in reducing mosquito borne populations – please see below in black.

    From the EPA – Children Are at Greater Risks from Pesticide Exposure | Pesticides | US EPA

    Children are at a greater risk for some pesticides for a number of reasons. Children’s internal organs are still developing and maturing and their enzymatic, metabolic, and immune systems may provide less natural protection than those of an adult. There are “critical periods” in human development when exposure to a toxin can permanently alter the way an individual’s biological system operates. Children may be exposed more to certain pesticides because often they eat different foods than adults.

    Children’s behaviors, such as playing on the floor or on the lawn where pesticides are commonly applied, or putting objects in their mouths, increase their chances of exposure to pesticides.

    Adverse effects of pesticide exposure range from mild symptoms of dizziness and nausea to serious, long-term neurological, developmental and reproductive disorders. Americans use more than a billion pounds of pesticides each year to combat pests on farm crops, in homes, places of business, schools, parks, hospitals, and other public places.

    The Center for Disease Control (CDC) has said that aerial spraying for mosquitoes is the least effect method of control. Also, on October 6, 2003, the U.S. Supreme Court set an important precedence for environmental protection. The Court upheld the 9th Circuit Court of Appeals’ ruling in, League of Wilderness Defenders vs. U.S. Forest Service, that aerial spraying constitutes a point source of pollution under the Clean Water Act. In defining aerial spraying as “point source” pollution, the Court has provided us with an additional tool to protect water and the rest of the environment from the detrimental impacts of aerial pesticide spraying.

    Here is a way less toxic alternative to this plan.

    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4257658/

    OCVC should be focusing primarily on education of Orange County to get the message to check weekly and dump standing water, which needs to happen ASAP and be an ongoing program. The regular promotion of the scary Zika messages the OCVCD promotes regularly takes away from the more useful single most effect means of mosquito control – is to get rid of the standing water in your yards – check the bottom saucers of plants – so the mosquitos cant breed to begin with.
