The worst bites come from mosquitoes. A mosquito’s proboscis, or mouthpiece, pierces your skin when it bites you in order to draw blood. It injects its saliva into the skin while it feeds (ick). The saliva triggers an allergic reaction in your body that results in an itching bump.

A basic household component, salt, works wonders for a bothersome mosquito bite. Salt contains antibacterial and anti-inflammatory qualities. To make a paste, combine a few dashes of salt with water. Next, coat the bite with the paste. The minerals in the salt will aid in drawing saliva from your skin, lessening irritation and itching.
