Mosquitoes are found worldwide and come in a variety of sizes and colors. Both males and females feed on plant nectar and fruit juice, which is burned as fuel for flight. Although mosquitoes rely on sugar as their main source of energy, the female needs to feed on blood in order to develop fertile eggs. Males do not bite. Although sugar must be replenished daily, blood is sought less frequently. Humans are not the primary target for blood; birds and animals are the principal blood

Anti-Mosquito Several factors deem to explain why mosquitoes will bite one person and not another. The best defense remains a good offense. Here is a list of things to avoid

Dark Clothing

Carbon Dioxide

Lactic Acid

Mosquitoes are drawn to dark-colors since most of them are nocturnal.

Human bodies emit more carbon dioxide when hot. A burning candle or a camp fire is also a source of carbon dioxide.

The body releases more lactic acid after exercising or after eating certain foods, such as salty foods and high-potassium foods.


Skin Temperature


Many insects are attracted to perfumes, hair products, scented sunscreens, and floral scents that are included in products such as fabric softeners, soaps and detergents.

Different types of mosquitoes are attracted to different temperatures.

Perspiration increases the humidity around the body which explains why bugs often follow us during outdoor exercise. Moist plants and bodies of water also lure them.
