Posts about Spartan Mosquito

Here are all my posts that mention the Spartan Mosquito Eradicator or the Spartan Mosquito Pro Tech. The company is suing me for my 2019 review (#1). If they hadn’t sued me I likely would have only a single post about the company, which very few people would ever read. But I don’t like bullies and I don’t think large companies should be allowed to use lawsuits to silence critics, so I added more. Please share.

Reporter?

There’s likely a fun story here. Owner of sandwich franchise becomes head of $100 million company that sells tubes of sugar water to kill mosquitoes. Here’s his pitch:

“We’ve come up with the most economical, easiest, most effective mosquito-control measure pretty much in the world” — Jeremy Hirsch, inventor of the Spartan Mosquito Eradicator (source)

Then he lashes out with SLAPP when naturalist/blogger from Pennsylvania (me) points out the obvious that device is a complete scam. Company then hires lobbying firm behind Brexit to get a “new and improved” tube approved by EPA (see #4). And it’s not over: in 2021 the class-action lawsuit (see #5) will likely subtract $5 million from Spartan Mosquito’s coffers, not counting the legal fees that are probably already in the millions. Will the FTC get involved like it has for other mosquito-control scams? Does the EPA care it’s been snookered?

Contact me for more details. There’s also extensive coverage of Spartan Mosquito on Twitter (99% of it from me). And the American Mosquito Control Association‘s Science and Technology Committee prepared an extensive report on the company and its devices.

To get a quick feel for the inventors and founders of Spartan Mosquito, here’s a Twitter thread featuring Jeremy Hirsch and Chris Bonner.

Experiments on Spartan Mosquito Eradicators

Research conducted in Florida found no evidence that Spartan Mosquito Eradicatiors are effective mosquito-control devices. Here’s the citation:

Aryaprema, V.S., E. Zeszutko, C. Cunningham, E.I.M. Khater, and R.-D. Xue. 2020. Efficacy of commercial toxic sugar bait station (ATSB) against Aedes albopictus. J. Florida Mosquito Control Association 67: 80-83. PDF

Laboratory experiment

Below is a rough reconstruction of the laboratory experiment they conducted. In each of the cages (BugDorm-2120), 100 male and 100 female tiger mosquitoes (Aedes albopictus) were released, then monitored for mortality at 24, 48, and 72 hours.

Below are the cumulative mortality data for the three cages. Result: the Spartan Mosquito Eradicator filled with the provided packet ingredients (treatment) did not result in higher mortality. I.e., there was no evidence the device killed mosquitoes under laboratory conditions.

Field experiment

The researchers also conducted a field experiment using two sites that had large populations of tiger mosquitoes (because of the presence of tires). At each site they deployed five tubes (separated by 4 m), switching whether the tubes were “treatment” or “control” tubes every 2 weeks. A BG-Sentinel trap (without carbon dioxide) was used to quantify mosquito numbers every week.

Below are the weekly numbers of mosquitoes caught in the BG Sentinel traps. Results: there was no evidence that presence of treatment tubes (filled as per company guidelines) reduced the numbers of mosquitoes at the sites.

Conclusions

The scientists concluded that “Both laboratory and field components of our study show that the Spartan Mosquito Eradicator is not effective in reducing abundance of Ae. albopictus.” They speculate that the contents do not attract mosquitoes and that the holes on the device (~3 mm) are too small for mosquitoes to easily reach the fluid inside. They also highlight the need for an experiment to evaluate whether the active ingredient (1% sodium chloride) kills adult mosquitoes. I.e., even if mosquitoes were attracted to Spartan Mosquito Eradicators and could easily get inside, the salt might not be lethal.

Update: the salt experiment has been conducted.
