Local health officials plan to spray for mosquitoes tonight in an
effort to control ongoing West Nile virus activity in Allen County.
Crews will spray within a half-mile radius of the 6000 block of Glenview
Drive, the 2400 block of Buckhurst Run and the 4600 block of Highwood
Spraying will begin about 8:15 p.m. but will not occur if the temperature is below 55 degrees, winds exceed 10 mph or it is
Although the pesticide used is a low-volume concentration that is considered safe for humans and pets, people are encouraged to
stay inside with their pets until the spraying is finished.
Hey, this is getting way too close for comfort. I live in this most recent spray area, and have lots of BUGS doing the natural buggy things in my urban wildlife habitat.
Pesticide Spraying: A Cure Worse Than the Disease? and there is evidence that their repeated use breeds resistance. Are we headed for 'super-mosquitoes'????
According to the Allen county health department, and the article in Scoop May 5 2010, there hasn’t been a confirmed human case of West Nile virus in Allen County in the last two years, article says that that doesn’t mean people shouldn’t be vigilant. With all the mosquito spraying over the years, don’t let spraying give you a false sense of security. Personal protection is the best prevention.
But it is equally important to recognize the public health hazards associated with widespread pesticide exposure from mosquito spraying in the last 10 years, or even more.
Fort Wayne is using AquaAnvil, a water-based adulticide, with the active ingredient sumithrin, for its mosquito control efforts in 2010. On July 12, 2010: The Jackson County Health Department announced their switch to Clarke AquaAnvil for their community wide efforts to control disease carrying and nuisance mosquitoes. AquaAnvil replaces the previous mosquito control mosquito spray which was oil based, with a new water based technology.
“This is a unique mosquito control chemical,” said Christopher Novak, Control Consultant for Clarke. "AquaAnvil replaces most of the oil in the mixture with water. The chemical droplet is protected by a water based carrier through a process called ‘colloidal suspension’. This allows the spray to be more potent and effective, and the elimination of the oil based carrier helps protect the environment.” Novak says the product also reduces container waste and provides economic advantages when compared to previous conventional methods. Paul Ramsey, Jackson County Environmental Health Director, adds that there is also less odor and less of a ‘fog’ so the new product is not only more environmentally friendly but also more people friendly.
Then why do we to still have to avoid the spray, stay indoors with the windows shuttered, and stay away from any surfaces sprayed upon??
Clarke says: AquaAnvil™ combines the proven performance of the active ingredient in Anvil in a new, unique water-based formulation. Together, you get a product that provides exceptional performance. The use of Droplet Optimization Technology (DOT) enhances efficacy even at low rates. Unlike other water-based products, AquaAnvil™ relies on evaporation to create a MORE POTENT, efficacious droplet(more power) that provides superior control from air or ground.
Anvil is one of the common mosquito pesticides, and sumithrin is one of the synthetic pyrethroids, man-made poisons that are copies of two poisons found in plants, that are neuropoisons, have irritatant and/or sensitizing properties, and are linked to endocrine disruption. They are extremely toxic to aquatic organisms, moderately toxic to birds,
Any pesticide spraying is harmful to ecosystems and wildlife.
Adulticides pose well-documented threats to wildlife, birds,
fish, shellfish, and beneficial insects such as bees, butterflies, and
dragonflies, which prey on mosquitoes.
Pesticide spraying often kills other types of mosquito predators, too.
Furthermore, wildlife and ecosystems depend on mosquitoes for
their survival. I, for one love to watch the birds, bees , butterflies, dragonflies, fish, bats(still seeing bats even though their numbers are being decimated) devour mosquitoes as part of one of the the natural wonders in my designated urban wildlife habitat.
When the Centers for Disease Control and Prevention Epidemic/Epizootic West Nile Virus in the United States: Guidelines for Surveillance, Prevention, and Control 2003 says that insecticidal adulticides do not pose UNREASONABLE health risks to humans, wildlife, or the environment, tells me that science can not prove beyond a reasonable doubt that judiciously spraying for adult mosquitoes reduces the incidence of West Nile Virus (WNV) in humans. Science has not answered that when questioned.
We do know that eliminating mosquito breeding sites, larviciding (killing larvae with a nontoxic product), and personal protection are more effective means of preventing WNV, and they are less harmful to human health and the environment.
No safe exposure level has been scientifically established for avoiding hormonal and other adverse effects, nor has the Occupational Safety and Health Administration (OSHA) set an exposure limit.
