Mosquito breeding prevention and factors that affect bite risk

Mosquitoes reproduce in standing water, so eliminating sources such as birdbaths, buckets, flower‑pot saucers, tires, clogged gutters and low‑lying garden spots reduces populations. Maintaining clean gutters, ensuring proper drainage, and keeping pools, ponds and fountains circulating or chemically treated also deters larvae development. Keeping yards tidy—regular mowing, trimming dense vegetation and removing debris—limits resting places for adult mosquitoes.

Research indicates that certain human traits attract more bites. People with blood type O tend to be more appealing, while type A is less attractive. Higher body temperature and increased sweat, such as during exertion or pregnancy, raise the likelihood of being bitten. Dark or bright clothing colors (black, red, orange, cyan) draw mosquitoes, whereas lighter shades (green, purple, blue, white) are less enticing. Consuming beer may also increase attractiveness, although the exact mechanism is unclear.
