Spraying poisonous chemicals can be very effective, but may harm life forms other than mosquitoes.

I wear a bug shirt as an effective alternative to bug spray.

Some DIY trap/attractant research and ideas:

  https://www.bg-sentinel.com/ (see design of device)

  -yeast (do not stir), brown sugar, filtered water
  -common trap design uses 2L bottle cut near top with top inverted and placed into lower section. mosquitoes fly into funnel-like area and lay eggs. important: opaque cover to block light, black supposedly attracts mosquitoes.
  -things to experiment with:
    -5 gal bucket design: inverted funnel, insect screen lid, fan to disperse attractant
    -other attractants: used clothing / shoes (soles) / octinol lures
    -soap to reduce surface tension to drown mosquitoes
    -some say bread works instead of yeast
    -other types of sugar
    -baking soda / citric acid or vinegar CO2 source (quick reaction, need to slow down)
    -mason jar (hydroponic) net pot - line with screen and make hole in bottom
    -fungus / mushroom CO2 sources
    -bt dunks in areas with standing water
    -3d print container/components
    -build bat house (benefit: guano for compost)
