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.
Adding vinegar and sugar water will not just get rid of mosquitoes, but pesky annoying gnats too.
Today, I made two mosquito traps from soda bottles. I did not have any black construction paper but did have black ground cloth.
