Victims inside Spartan Mosquito Eradicators
Per inventor of the Spartan Mosquito Eradicator, mosquitoes are initially attracted to the CO2 released by fermenting sugar, enter the device through small (5/32") holes in the lid, drink some fluid, exit through the same holes, then later die when their stomachs rupture from combination of yeast-produced CO2 and sodium chloride.
As an avid follower of various gizmos that kill mosquitoes, I was curious whether I could find evidence of a mosquitoes entering the containers. My hypothesis is that the mosquitoes would never, ever crawl through a hole to get to fermenting sugar water. Especially something 5/32" in diameter. Never going to happen.
So I bought two for my yard (Swarthmore, Pennsylvania) and I've been taking photographs of insects and spiders that die within. The yellow card is not part of the device but I added it trap insects that might enter but that might not drown. Not shown are many, many small insects that drown and then rot into unidentifiable blobs. I haven't found a single mosquito.
