Dan Rojas trapped 8,000 mosquitoes in two nights using this Mosquito trap by adding seltzer water CO2 as an off-the-shelf and recyclable attractant. (You can also use a pet, or farm animals – don’t worry they won’t get bitten.)
He uses high-powered industrial fans – available at a hardware store for upwards of $100 – a leaking seltzer bottle, and mesh held in place with rare-earth magnets (strong bond, powerful enough to resist the fan). The mesh catches bugs, pollen, leaves etc.
- He uses meshes on industrial-strength fans to trap the mosquitoes en masse
- CO2 from a seltzer bottle or the breath of his dog Rocky acts as bait for the bugs
- Rubbing alcohol is then sprayed on the trapped critters to kill them quickly
- It evaporates leaving no residue – so lizards and ants can eat the bodies
