If you’re even remotely interested in killing mosquitoes, you’ve probably seen ads for plastic tubes that are filled with water, sugar, and yeast. The marketing pitch is that the thousands of mosquitoes lurking in your yard will be drawn to the devices by carbon dioxide (emitted by yeast when it consumes sugar), then will all enter the device through tiny holes at the top, ingest some of the fluid inside (because mosquitoes forage for sweet liquids like nectar), squeeze back out of the tube through the same holes, and then die due to the effects of a chemical (table salt, boric acid, garlic oil, etc.) dissolved in the fluid. According to marketing claims, these tubes will completely rid your yard of mosquitoes for months.
Below are details on the eight such devices currently marketed in the United States.
Spartan Mosquito Eradicator
First sold in 2016 as the Spartan Mosquito Bomb, the company says these tubes will eradicate mosquito populations for up to 90 days. Active ingredient is table salt.

Do any these devices kill mosquitoes?
Only one of the above devices (the Spartan Mosquito Eradicator) has been evaluated by third-party scientists. Here’s the PDF of that journal article — device was determined to be ineffective. More generally, Yee et al. 2020 tested whether salt can kill adult mosquitoes — no.
