Menlo Park: After fogging, no mosquitoes test positive for West Nile virus

Original post made on Aug 14, 2014

After fogging 1,300 acres of Menlo Park with insecticide, the San Mateo County Mosquito and Vector Control District announced that none of the dead mosquitoes collected tested positive for West Nile virus.

It is dismaying to say the least that many residents of Menlo Park were not notified in advance of the spraying nor given the opportunity to close windows, put pets indoors, etc. Though it is obviously in the public interest to protect against West Nile, at the same time both the county and the city have an obligation to notify ALL affected residents in advance of any activities like this one.

Let's rephrase this:

After killing numerous insects in addition to the targeted mosquitos indiscriminately, some of which were beneficial to our local environment, in the name of 4 cases of West Nile infection in all of California, there appears to be no evidence of this relatively benign disease in the area. Officials, perplexed, are now wondering why they were so worried about a virus where the vast majority of infections are completely asymptomatic and without any detectable consequence.

Officials are not scrambling to cover up the costs -- economic, environmental, and potentially health related.

Unfortunately, it is not obviously in the public interest to protect against West Nile. For every action, there are costs and benefits. The benefit, if any, accrued here do not seem clearly justifiable.

Outrageous on all fronts. I found two dying honeybees on a back table.

The lack of public knowledge well ahead may be due to the responsible actions of other communities some years ago, like Santa Cruz, where residents protested, city council delayed the spraying, got the word out and buses transported those with serious conditions, elderly, newborns, etc. out of town for the night. I don't have detailed material, like bus payment, etc. I also don't know if the spraying concerned Santa Cruz proper or the entire county.

Since we pay and vote for county representatives, perhaps it's time to write them, news outlets, distribute pamphlets, etc. so this nor any other public action is undertaken without people's awareness, and reasonable input. I'd also like to know where the MP City Council (aside from Mayor & Mr. Pine) stands on this, person by person.

Probably, not possibly, they'll find more WN infected birds and mosquitoes down the road - after all, birds fly.

Would the County Board of Supervisors please respond publically:
1. Why were residents not noticed on each front door of the chemicals, the date and time of the fogging?
2. Why were residents not given an opportunity to vacate, close doors and windows, keep pets inside, cover bird feeders & pet food dishes, etc.?
3. Why have residents not been made aware of how to "clean" chemicals off of areas such as outdoor tables, chairs, pet food eating areas, etc.?
4. Why were residents not made fully aware of the chemicals used with regard to known toxicity and side effects?
5. Why were residents not given an opportunity to protect themselves and their homes from the poison?
6. Of course a poison intended to blanket an entire 1300 acres and kill insects is also killing bees, birds, and the many beneficial insects as well as affecting humans, some extremely sensitive to toxins. Why?????
7. County vector officials have visited my residence three times in the last 8 months. Why could they not take the time to properly inform, warn and prepare residents for the drone dumping of poisonous chemicals indiscriminately?
8. Have any Supervisors & County Officials read "Silent Spring"? How can we be so ignorant after all these years of proven death and destruction by the use of such chemicals? Please tell us why.

Every commenter so-far obviously has no background in science and rather prefers to be reactionary. Before making foolish comments and creating an absurd list of "questions" no one asked for information about the specific chemical that was used. Do they really think that the Public Health Department would allow such activity if there was even the remotest chance that it could injure people or pets? Do any of you realize that this fogging material is active only against flying insects that are airborne at that moment and that it becomes totally inactive when it settles to the ground moments later? Do you know that it is so non-toxic that the technicians who spray it are not even required to wear masks but are trained and state-licensed to do so? How many insects besides this variety of mosquito are flying about in the night? Certainly not beneficial ones like bees. Get off your high horse and seek some scientific knowledge from experts before you go off on such an illogical tirade against a service that has saved lives on the peninsula and across America for generations now. Then get down on your knees and thank God for the progress science has made that has saved or protected you from dread mosquito-borne diseases like Malaria, Yellow Fever, Dengue Fever, West Nile Virus, etc, etc that were prevalent in the past and still are killing thousands in third-world countries. Every peninsula town has a representative on the San Mateo County Mosquito and Vector Control District Board of Trustees. Do you know who yours is? Have you contacted him or her to gain more information? Obviously not. Those who have done their homework would not write stupid posts such as all those above.

Are you referring to this one, posted on SM site? If not, would you please share your source of information?

It's much worse than most of imagined.
See this link: Web Link

The chemical they used is a neurotoxin and is carcinogenic, and it lingers for months. To quote the article linked above: "In 60 days there is still 25% left, in 90 days 12% is still present and even at 210 days there is still 3% present on the soil." "The truth of the matter is that the chance you are going to die from the West Nile Virus is extremely unlikely. Your health is put at a much higher risk of harm from mosquito fogging than it is from West Nile Virus."

CALMDOWN displays touching trustfulness in the pesticide industry, and governmental agencies like the poorly run San Mateo Vector District whose chief was recently booted out by the Board for hiring a convicted embezzler without vetting her, and she of course embezzled like crazy from our district.

By the way, there is a pending lawsuit in Santa Clara County over this insane, poisonous "fogging".
Menlo Park residents should let our City Council, our Supervisors, and the SM Vector Board hear our objections to having our properties sprayed with carcinogens and neurotoxins.

Love comments like the one from CalmDown: "Every commenter so-far obviously has no background in science and rather prefers to be reactionary."

It's like the classic post one sees in comment threads akin to "Your [sic] an idiot" which reveals as much about the poster's own ignorance than the intelligence of the intended target of the post.

There's nothing to "calm down" about here. It's foolish paranoia to think that our environment is teeming with organisms on the cusp of killing off the fragile human species ... you know ... the one that is near 7 billion and growing and taxing this planet's resources even in "disease infested" areas like Africa. On top of that, we don't live in Africa. If and when our environment poses those threats, then by all means, take necessary measures.

You keep buying snake oil fella. The rest of us will trust more in the homeostasis of most biological and ecological systems in our relatively safe and "sterile" environment. And yes, I did contact our local Vector control officer. That's how I know that there have been 4 West Nile encephalitis infections in all of California. He cited that as a concern. I look at that and wonder if anybody making decisions knows the definition of a denominator.

There's *always* more natural ways to deal with the environment. We are screwed by legal regulations and red tape we are stuck with, flaws and all. This is not just a knee jerk reaction, there's a ton of examples if one just adds it to their daily reading but you need to learn how to really use your web browser to research. It's not too hard, just dig more because result pages are ranked, use a variety of browsers & search engines:

Why do we have to spray pesticides for such a low rate of incidents:
Web Link

Then if one reads up on the % of people infected becoming serious or fatal, you'll see how this is all a knee jerk reaction on the other side.

Seriously, I'd rather they "fog" hospitals for high rates of infection:

Better yet, fog the trolls like "calmdown".

Don't miss out on the discussion!
