On Indiscriminate Mosquito Spraying: Open Letter to South Florida Mayors from Mayor Philip Stoddard, South Miami … by gimleteye

The letter written this week by South Miami Mayor Philip Stoddard -- who is a professor of biology at Florida International University -- expressing outrage at indiscriminate mosquito spraying is grounded both in science and personal observation and investigation.
In the early 1960s a mosquito spray truck would make the rounds in the small coastal New England town where we stayed in the summers. I recall its sweet, sickly odor and how sometimes we ran delighted through the fog it left behind. Who knew? A decade later, in the early 1970s, on winter vacations I stayed at the home where my father and mother lived in Marathon in the Florida Keys and would occasionally be woken at night by the drone of an overhead airplane and later the same scent of insecticide would waft through the open window.

The Keys exposed me to entirely different coastal environment. I grew to love immensely the shallow sea grass meadows, the flats and green islands dotting Florida Bay. The Florida Keys backcountry opened my eyes to spectacular demonstrations of biodiversity. Who knew that the early 1970's would be the last moment, in our lifetimes, that the Everglades ecosystem could be viewed -- on certain days -- in its full glory and splendor?

On winter visits to Marathon, one could spot at the north end of the tiny airport (then), DC3's marked "Monroe County Mosquito Control". Later in the 1980's, when I became involved in Monroe County politics and struggles to protect the Keys fragile environmental resources, I learned that no local government agency was better protected or more insulated from outside criticism than the mosquito control board. You could penetrate the equanimity of the county commission but you couldn't touch the people or the mission of the agency that killed the mosquitos.

There was not much evidence at the time, or money to focus on the question that seemed obvious: how had mosquito spraying contributed to the dramatic decline of wildlife and near shore fisheries comprising the tail end of the Everglades ecosystem in the Florida Keys? For example, in the early 1970s, when you drove down US 1 towards Key West, the overhead lines would be literally festooned with carcasses of white herons. You scarcely see white herons any more.

The letter written this week by South Miami Mayor Philip Stoddard -- who is a professor of biology at Florida International University -- expressing outrage at indiscriminate mosquito spraying is grounded both in science and personal observation and investigation.

In his letter, Mayor Stoddard may have found a better way of reaching through to people who mostly experience mosquitos as terrible pests that threaten human life in Florida. In fact, they increasingly do because of emerging mosquito-borne diseases like dengue and chickungunya; diseases that are being carried north from the tropics as a result of a man-made, warming climate.

Mayor Stoddard strikes another chord that resonates. How the world's largest chemical companies have succeeded in marketing chemicals to destroy insects and pests in defiance of common sense: that these highly adaptable species can evolve to develop immunity from chemicals that end up actually causing more harm to us. A business model using human vulnerability as a catalyst for a potent stream of profits.

The real and present danger to us is hubris; that's what indiscriminate chemical spraying of mosquitos represents. The ancient Greeks streamed into amphitheaters in un-airconditioned, open air venues -- probably swatting at mosquitos the same way we do -- to watch the works great dramatists with no benefit of word processors, microphones, or flashlights to guide them safely to their seats.

Our ancestors experienced what we do not: that the outcome of pride, over-confidence in our own works and refusal to entertain alternatives to our own instant gratification can bring down kingdoms, fortunes, and make tragedy from happiness in an instant.

So when you hear that buzzing in your ear, but no butterflies, no squirrels, no bees, insects or birds except ravens and vultures, imagine for a moment that is the soundtrack for our competition with pests, scavenger species and reptiles who survived the last great extinction more than 60 million years ago.

We are not children running with delight behind the mosquito spray truck any more.


Tonight, the county is conducting an aerial spray of our towns with the organophosphate insecticide “naled" (trade name “Dibrom").
This spraying is being done solely to take a temporary swipe at nuisance salt marsh mosquitoes for the short-term comfort of our residents.

This practice has nothing to do with disease control. Just the opposite, it paves the way for diseases to move in without control. With every indiscriminate spraying, disease-carrying mosquito species move one step closer to evolving resistance to organophosphate insecticides, just as some species of mosquitoes have already done with naled and virtually every other insecticide used to date. We need to retain insecticide efficacy for localized use in suppressing arbovirus disease outbreaks, in particular Dengue & Chickungunya, which are moving into our county. To spray large areas is completely irresponsible. Mankind has done this experiment over and over and it comes out the same every time. When do we learn from past mistakes? Ever? South Florida was made safe and habitable primarily through elimination of temporary water sources where mosquitoes breed. Newer complimentary control methods include larvicides and larval growth inhibitors, but nothing works so well as old-fashioned water control.

I have met twice with county officials from the Mosquito Control Division. They have assured me that the insecticides are harmless to butterflies other “non-target” species. When I asked, they could not cite any studies to this effect. I consulted with the experts and found it was not true. Naled has a long history of problems, and evolution of insecticide resistance by mosquitoes is just one consequence of overuse. Here are some things to know about this insecticide:

Naled has been found to be 400-4000 times more toxic to butterflies than to mosquitoes and is believed to have caused the initial decline of the Schauss swallowtail butterfly on Key Largo.

Naled is said to break down relatively quickly. This is true. It breaks down into dichrorvos, which is also an insecticide.

The American Bird Conservancy petitioned the EPA to ban application of naled because of its high toxicity to songbirds.

The Natural Resources Defense Council sued the EPA over the use of nailed.

Naled is no longer used in flea collars because it harmed pets - my own cat fell over when we fitted him with a naled-infused flea collar.
Broward County will not spray naled within two miles of Butterfly World in Coconut Creek.

As an immediate and direct consequence of tonight’s aerial spraying with nailed:

We will lose ~2/3rds of our butterflies and most of their larvae.

Our foliage will be toxic to bees and caterpillars for a day.

Endangered bonneted bats in the affected area will temporarily lose their food supply just as their young are foraging independently. (This action constitutes an unauthorized “taking" under the Endangered Species Act).

Veterans with Gulf war syndrome who venture outside will be exposed to chemicals to which they are already sensitized.

Mayor Gimenez has instructed his staff to notify residents prior to spraying so that they may take any necessary precautions. For County staff to notify select municipal officials at 3:15 pm on a Friday afternoon, just a few hours before spraying, does not give anyone sufficient time to notify our residents.

My Commission has not given our permission for this practice, which FIU toxicologists and UF entomologists and consider environmentally reckless and largely ineffectual at addressing the human mosquito problem. I have repeatedly voiced my objections. Yet the county does it anyway to appease ignorant residents who complain about mosquitoes but don’t understand the adverse consequences of spraying. The practice is no different than doctors prescribing antibiotics for patients with viral infections to make it seem like the doctor is doing something to help, knowing full well that antibiotics are useless on viral infections but promote evolution of antibiotic resistant pathogens to the long term detriment of the patient and the population at large.

As a scientist with a deep background in population biology and evolution, I am more than displeased. I am genuinely angry at what I consider a foolish chemical assault for a temporary convenience with long term negative consequences to our species and many others. Hopefully, on Tuesday night, my City Commission will vote for an ordinance and resolution pair that allow South Miami to opt out of the unnecessary spray regime and reserve insecticide sprays for infrequent localized application in treating outbreaks of emerging arbovirus diseases. I urge you to consider similar measures in your municipalities.

That's funny - I live right across the street from Mark and Lynda Bell and last night I saw one of the mosquito control planes fly not only over my house but the Commissioner's as well.

Again, you have wrong and misleading information.

Also, why dosen't the good Dr. address his own County Commissioner, the Honorable and Consistently Absent, Xavier Suarez?

I see nobody from HIS office in his email addresses he sent.

Mr. Suarez should be made aware of this too. Don't you think?

I wonder how effective propane mosquito systems are, it used to be on sold at Home Depot and it was billed as being used at golf courses covering a few acres per machine. If they are truly effective then setting them up in summer seasons across most affected areas may be a worthwhile investment. Any biologists or entomologists out there?

The biographical piece by Stoddard may describe correct science. we don't know, the bibliography is absent, also absent are epidemiological studies about what happen to people who contrast mosquito born diseases.
Another cavalier notion from a mayor who, just in the last few months approved to put 150 people cramped in tiny apartments with barely a tree in sight. He also proved to be a poor steward of nature by bypassing SM laws to denude numerous lots in South Miami. he approved a horrid new tree ordinance written by his henchman , the former manager of Cutler Bay. Take a look in South Miami if you want evidence .
What about all those displaced butterflies?
The butterfly article is nothing but a diversion from what is really going on in South Miami.

Maybe the mayor should put out a call to Batman, have him construct batcaves all over South Florida to get rid of the problem of mosquitos.

Dada, dada, dada, dada, dada, dada, dada. dada BATMAN!!! Stoddard would make a good Robin.

So, an area representing about 4% of Miami Dade County was sprayed and has caused all the environmental problems stated. Perhaps, habitat destruction and paving over 98 percent of the original pinelands in Miami-Dade County might have an affect on our precious native species also. Please donate to Tropical Audubon Society to help save what little remains of our natural areas.

We have an individual propane mosquito system set up in our backyard and it really helps.

It lures and catches them instead of toxic chemicals.
Funny thing is that we rarely have to empty the trap - a few anole lizards have found perfect hunting spots right near the trap entrance and have enjoyed many mosquito meals.

The Mayor's agenda to stop mosquito spraying is based upon opinion and not on science or factual information.

The reason we see less wildlife in South Florida today is because of habitat loss.

If the Mayor's agenda is adopted and no-spraying is allowed in South Miami, then mosquitoes will prosper, public health will suffer and residents will be subjected to increased threat from mosquito borne diseases. For what benefit? Not sure .......

But the Mayor THINKS that butterfly populations will increase. Remember ...... the Mayor who studies communication in fish at FIU, has absolutely no background in environmental toxicology. I'd like to hear which professionals in the field of mosquito control he has consulted? The Florida Mosquito Control Association? The American Mosquito Control Association? Maybe he has spoken to a toxicologist at the US EPA? Id be interested in knowing what factual information that the Mayor has in his crusade to stop mosquito spraying in South Miami.

If you look at the map of South Florida, mayor Stoddard's little city is but s speck next to the giant swamp known as the Everglades. Let the mosquitoes, butterflies, moths and other critters multiply there. They don't spray in the Glades now, do they? How do Stoddard's silly green edicts help the health and welfare of his constituents?

Just wait until someone in South Miami catches a dreadful disease from mosquito bites and gets a smart lawyer...

is it a pond or a pool in south miami mayor stoddard backyard?!?!?

Mosquitoes and their predators have co-existed for many millions of years. Mosquitoes will seek out places in a pond where the possibility of survival for the next generation is the highest. Egg laying female mosquitoes will seek sheltered areas in any pond to lay eggs. Areas such as water trapped in the top of planter pots, very shallow margins, water in gravel or between rocks, algae mats or thick emergent aquatic plants and areas sheltered by overhanging plants provide protection against predators (fish and insect).

who else has a pond/lake in their backyard in south miami??

"You always have to protect yourself when you're using any chemicals, no matter the grade," Holland said. "You have to wear a long sleeve shirt, long pants."
The chemicals his workers are using are known as herbicides and "insecticides, designed to kill invasive plants and ward off bugs like mosquitoes. The most common chemicals used are glyphosate 2, 4-D, and permethrin. Dr. Phil Landrigan, professor of pediatrics at New York's Mount Sinai Hospital, studies the effects of these chemicals on humans, in particular children and pregnant women. "I think the fact that they have been around for a long time engenders a false sense of security," Landrigan said. This week, he presented his findings at a congressional briefing on the health risks of overexposure."There is also concern that pesticides of all kinds can damage the developing nervous system and can result in learning disabilities in children, behavioral problems and possibly chronic diseases like Parkinson's," Landrigan said."
