What preventive measure can be taken during summer gatherings outside to deter mosquitoes?

Using citronella candles or coils is an effective preventive measure to deter mosquitoes during summer gatherings outside. Citronella is derived from the leaves and stems of different Cymbopogon species, and its scent is known to repel mosquitoes. When lit, these candles release aromatic compounds that mask the natural scents that attract mosquitoes, making your outdoor space less inviting for them.

While wearing long-sleeve clothing can provide a physical barrier against bites, it may not be as effective in masking scents and repelling mosquitoes directly. Setting up a fan to create wind can help, as mosquitoes are weak flyers and wind can disrupt their ability to navigate, but it might not be as reliable or widespread in its effectiveness as citronella products. Applying sunscreen, while important for skin protection from UV rays, does not detour mosquitoes and may not contain any repellent properties, although some formulations might incorporate insect repellents. Thus, using citronella candles or coils provides a direct method of repelling mosquitoes effectively while enjoying an outdoor gathering.
