Heat
Increasing the temperature of your insect bite may also provide comfort. There is no proof that it works, but you may purchase a specific gadget, such as BiteAway, that administers direct, regulated heat to the bite. This is said to relieve swelling and irritation. Although the therapy is quick, these instruments can be costly.
To get a similar effect, immerse a clean towel in water that is as warm as you can stand comfortably (but be careful not to burn yourself). Wring the cloth out and place it on the bite. Continue to soak the towel for up to 10 minutes to keep it warm. Heat treatment should not be used on an open wound.
