BLSG Board resists compliance with state request

In advance of last Thursday’s BLSG Board of Trustees meeting, Mike Blaisdell, BLSG Chair, called Patti Casey of the Vermont Agency of Agriculture. He wanted to discuss a statement Casey had made two weeks earlier. Casey was responding to the annual report that BLSG had submitted for inclusion in the Town Reports of BLSG’s member towns. The report included false claims about the ability of BLSG activities to reduce the risk that a resident will contract a mosquito-borne disease.

Casey’s response was unequivocal and confirmed our position that 1) BLSG is not authorized to mention that their operation has any impact on mosquito-borne disease, that 2) truck-mounted adulticide spraying has no substantial impact on mosquito-borne disease, and that 3) BLSG has been avoiding state recommendations and honest public relations for some time.

Before the board meeting Blaisdell had conferred with Jeff Whiting, BLSG Vice Chair representing Goshen, and decided that they would recommend that the Board comply with Casey’s requests to change BLSG’s stance on this issue. Blaisdell told the board that evening; “We feel that we shouldn’t say anything about the diseases that mosquitoes carry … because, one, it does look like we are trying to campaign off of the diseases that they carry.” There was an immediate response from Will Mathis, the BLSG Operations Manager; “Aren’t we?” This set the stage for a 15 minute discussion of whether BLSG’s longstanding strategy of overstating the risk of arboviruses to garner support for their activities was a good thing or a bad thing.

BLSG’s arbovirus disinformation earns another state rebuke

Last month, the Salisbury Select Board deleted a paragraph in the annual report submitted by BLSG for inclusion in the Town Reports of BLSG member towns. The offending paragraph suggested that BLSG’s activities reduced the risk of residents contracting a disease from a mosquito bite. This type of false information has been repeated by BLSG for many years and we have been asking them to stop for at least two years. BLSG’s message is demonstrably false but their website and public statements continue the disinformation campaign despite direct rebukes from state officials.

Today, Patti Casey, the Environmental Surveillance Program Director at Vermont’s Agency of Agriculture, offered another strong reprimand. Patti Casey copied the following statement to us and to two state officials in Vermont’s Agency of Agriculture and Department of Health. The statement confirms our position that 1) BLSG is not authorized to even mention that their operation has any impact on mosquito-borne disease, that 2) truck-mounted adulticide spraying has no substantial impact on mosquito-borne disease, and that 3) BLSG has been defying state recommendations and honest public relations for some time.

Arbovirus disinformation

The leadership of BLSG regularly mentions mosquito borne diseases when describing the services they provide. Their message is that BLSG’s operation reduces the chances that residents of the BLSG District will contract a disease from a mosquito. The BLSG leadership’s message is wrong, and it is inappropriate for them to even include this topic in public discussions.

Arboviruses in Vermont

Despite BLSG’s continued reference to a long list of tropical diseases, there are only two arboviruses carried by mosquitoes in Vermont: West Nile virus (WNV) and eastern equine encephalitis virus (EEEv). The human illnesses caused by these viruses are extremely rare in Vermont.

Vermont avoids New England’s big year for EEE

Southern New England had a big year for Eastern Equine Encephalitis in 2019. There were 20 reported human cases of the EEE virus (EEEv) in Massachusetts, Connecticut, and Rhode Island with nine deaths. This is the most cases in a decade including the last outbreak year of 2012. To the east and west of Vermont, New Hampshire and New York had no human cases of EEEv, but dozens of mosquito samples were positive for EEEv. Vermont did not have any human cases of EEEv in 2019, and no EEEv was found in 3217 samples of mosquitoes tested.

The risk from Eastern Equine Encephalitis in Massachusetts in September at the height of the season. The risk is derived from the number of mosquito pools testing positive for EEEv and other factors. Two towns on the Vermont border (upper left) had positive pools, but no EEEv-positive mosquitoes were found in Vermont.

BLSG annual report says it all

It’s nice to see a kite aerial photograph on the cover of the new town report.

Vermont’s town clerks will soon be mailing us our town reports, and Salisbury has already posted a pdf of the new 2018 Salisbury Town Report at its website. It includes an annual report from the Brandon Leicester Salisbury Goshen Pittsford Insect Control District (BLSG) which will appear in town reports throughout the District. The BLSG report includes some good information and some that is misleading.

Rare and rarer

There has been a lot of scary information about mosquito-borne diseases repeated by employees and board members of BLSG. There are two serious diseases carried by mosquitoes in Vermont, and one killed two people in 2012. That fact alone deserves our attention, but how much should we be concerned about these diseases?

What’s in the CDC report for Vermonters?

Every week, the Centers for Disease Control and Prevention (CDC) releases a report on diseases, and last week’s report was about the rise in diseases spread by insects and ticks. This was a typically dry and technical report about trends between 2004 and 2016 in human cases of 16 diseases spread by ticks, mosquitoes, and fleas. The CDC also publicized this report at their Vital Signs site where the hype was cranked up by a dramatic video and some revealing graphs.

BLSG doubles down on Zika scare tactics

There is some very useful information in yesterday’s Rutland Herald article by Will Mathis, Director of Operations of the BLSG Insect Control District. So it was disappointing to see the group is still misleading residents about the risk of contracting the Zika virus from mosquitoes in Vermont. The article mentions that insect borne diseases are part of their justification for controlling mosquitoes, and then adds “Vermont has now recorded its first case of the Zika virus.”

The Vermonter with Zika did not get it from a mosquito bite in Vermont or anywhere north of Florida or Texas. That Vermonter had travelled to an area where Zika is present. Zika virus and the primary mosquito vector of the disease (Aedes aegypti) are not present in Vermont (more here).

West Nile virus in Vermont

Avoiding mosquito-borne diseases like West Nile virus is a primary motivation for mosquito control. Since it was first confirmed in the US in 1999, West Nile virus has infected more than 46,000 people in the US and more than 2,000 people have died. Mosquitoes infected with West Nile virus have been found in every Vermont county in past years, so this threat should not be ignored. However, between 1999 and 2016, only 12 cases of West Nile virus were reported in people in Vermont (Figure 1).
