Jeremy Hirsch, inventor of the Spartan Mosquito Eradicator

Spartan Mosquito v. Colin Purrington

AC2T, Inc, a Mississippi company valued at over $100 million, is suing me in Federal court over my review of the Spartan Mosquito Eradicator. The device is a plastic tube filled with sugar, salt, yeast, and water and is purported to act as an attractive toxic sugar bait. Box claims that device will eradicate (kill) approximately 95% of mosquitoes in a yard for 90 days — the company does not release efficacy data, but claims it possesses them. My opinion is that the devices don’t kill mosquitoes, and the above review explains my reasoning. The owners, Jeremy Hirsch and Chris Bonner of Hattiesburg, Mississippi, seem particularly upset that I shared my review with state pesticide officials as well as federal regulatory agencies (EPA, FTC). The suit was brought to bankrupt and silence me, so it’s a SLAPP (Strategic Lawsuit Against Public Participation).

Here’s the first part of my motion to dismiss the lawsuit:

“In this lawsuit, Spartan seeks to use its superior financial resources to silence a former college professor who has been exercising his constitutional rights to petition his government and advocate on an important environmental and public health issue: the effectiveness of commercially available mosquito control devices. In Mr. Purrington’s opinion, based upon his personal evaluation of Spartan’s product and his scientific knowledge, Spartan has made false and misleading claims about the efficacy of its product, thereby violating federal environmental regulations and potentially endangering public health. Most of the statements that Spartan cites in the Complaint reflect Mr. Purrington’s efforts to reach federal and state officials with information about Spartan’s misleading and false claims concerning the efficacy of its product. The remaining statements reflect Mr. Purrington’s efforts to raise public awareness of the matters about which he is petitioning, describe his own opinions, or contain facts that Spartan does not, and cannot, deny are true. Applicable law does not provide Spartan with a valid claim against Mr. Purrington under those circumstances. Notably, even if Spartan could show that Mr. Purrington should be liable for his statements, Spartan fails to plead facts that would suggest it has incurred even a cent of damage to its business to justify its claims. That omission suggests that Spartan has sued merely to intimidate Mr. Purrington rather than to recover any demonstrable damage to its business. For those reasons, Mr. Purrington respectfully requests that the Court dismiss the Complaint in its entirety, with prejudice.”

Spartan Mosquito, Jeremy Hirsch, and Bonner Analytical Testing Company are being sued in New York District Court for fraud. Here is the 16-page complaint.

Scientists in Florida concluded the Spartan Mosquito Eradicators do not work.

DIY trap to kill pregnant mosquitoes

This post contains photographs and construction tips for a killer craft I made: an autocidal gravid ovitrap. Pregnant females enter the trap, lay some eggs on or near the stagnant water within, then are prevented from exiting and die. Their progeny also die because a screen at water level prevents larvae from reaching the surface to obtain oxygen. When similar traps have been deployed they bring down mosquito levels substantially and thus are quickly becoming one of the main ways to prevent mosquito outbreaks and disease. Every homeowner should have six. They’d make wonderful gifts.

Autocidal gravid ovitrapThe design features a clear dome that helps trap the females when they are done ovipositing (they go for the light), plus a completely unneeded observation window so I can watch the larvae and pupae (fun for the whole family, plus good for demonstration purposes). It borrows general methodology from gravid Aedes traps (GATs) designed by Dr Scott Richie (James Cook University) and colleagues that recently made news on NPR (here’s an overview; here’s their paywalled journal article). I’ve designed mine to capture species that also lay egg rafts, so it’s not just a GAT. My design doesn’t use insecticide because I wanted the odor of developing larvae to be an attractant to other females (it is, by the way).

What you need

  • Autocidal gravid ovitrap2-gallon bucket
  • bucket lid
  • 6″ plastic pot
  • clear dome from cake store
  • metal coat hanger
  • plastic screening
  • stapler
  • 3 paperclips
  • small neodymium magnet
  • silicone adhesive glue
  • duck tape
  • hardware cloth
  • 1-L soda bottle
  • 1/4″ foam weatherstripping
  • black spray paint
  • Dremel tool with cutting bit
  • drill with drill bit
  • knife
  • safety glasses (when Dremeling)

Construction photographs

If you’d like to see photographs larger just click on first image and navigate like a slide show. There are many ways to construct these so if you build one and it looks completely different, don’t worry. This is because if your device is the only stagnant water around, females will use it.

I’ve only just deployed it and it’s rather cold right now so I don’t have any victims yet. But I’m optimistic and am posting now with the hope that somebody will have suggestions on how to improve the design (I’m making more). One improvement I’m definitely going to make is to drop the funnel lower into the dome so it’s harder for females to accidentally fly straight up to escape. And pro-tip if you make the above: attach the lid to pail when spray painting to avoid unwanted buildup where they attach.

I’m also posting in the off chance that a biology teacher might take an interest. Having teams make these would be really fun and then they could deploy them in the woods near the school: bonus points for team that traps the most mosquitoes. It’s fun like the classic egg-drop lab in physics except useful. Students would then take their projects home where they’d continue to be useful. Would make for a great Girl Scout Gold Award / Eagle Scout project.

Where to buy

If all of the above sounds like way too much work you can buy traps from SpringstarBioQuip, and Ultimate Mosquito Traps.
