Updated for 2026. Between summer rains, irrigation, and the Everglades next door, mosquitoes are part of South Florida life. Beyond itchy ankles, some species can transmit viruses — which is why county mosquito-control programs matter, and why small yard habits add up.
First: dump the breeding water
The highest-ROI move is still removing standing water: saucers, clogged gutters, toy buckets, boat covers, and plant trays. Empty or scrub weekly. Screens, fans on patios, and dusk/dawn long sleeves help too. Homemade traps are a supplement, not a replacement for source reduction or professional/county control.
DIY bottle trap (classic yeast + sugar CO2 lure)
Mosquitoes are attracted to carbon dioxide. A simple fermenting mix inside a 2-liter bottle can lure some into a funnel they struggle to exit.
You’ll need:
- 1 two-liter plastic bottle
- About 1 cup water
- About 1/4 cup brown sugar
- A small amount of active dry yeast (about 1 gram / a pinch-to-teaspoon range — follow package common sense)
Steps:
- Cut the bottle in half.
- Dissolve brown sugar in warm water; let it cool.
- Pour the sugar water into the bottom half; add yeast (no need to stir vigorously).
- Invert the top half as a funnel into the bottom; tape the seam.
- Wrap the lower bottle in dark paper or cloth; place outdoors away from where people gather if possible.
Refresh the mixture every week or two, or when it smells spent. Results vary by species, weather, and competing breeding sites nearby.
Safety and expectations
- Keep traps away from curious pets and kids.
- Do not add pesticides to DIY sugar traps unless a product is labeled for that use.
- During heavy outbreak periods, follow county health / mosquito-control advisories.
