Today, I made two mosquito traps from soda bottles. I did not have any black construction paper but did have black ground cloth.
Adding vinegar and sugar water will not just get rid of mosquitoes, but pesky annoying gnats too.
Because mosquitoes are attracted to the CO2 we breathe out, I started looking for ideas that used CO2 as the bait for the mosquito trap. I did think of dry ice but it does dissipate fairly quickly.
