The solution is to use a device that can concentrate localized heat right on the bite. It turns out there are a number of products on the market that do just that. The Therapik Mosquito Bite Reliever is a small, affordable battery-powered device that works extremely well in my experience.

A bright light comes on inside that quickly heats up the affected area. The suggested hold time is around 20 to 30 seconds or to the point where the pain becomes unpleasant. Some people make the mistake of turning off/removing the device as soon as they feel some heat which is typically within five seconds or so. But it is important to maintain a connection long enough that the affected area is thoroughly heated up to the point of discomfort.

I read a German clinical study of a similar (but more expensive) product in which they concluded: "Locally administered, concentrated heat, which was recognized by the patients as a very short and targeted induction of almost painful high temperature on the skin, led to a fast improvement of ... swelling, pruritus (itching), and pain ... symptoms. Compared with alternatives of pruritus and pain treatment after insect bites/stings, (it) seems to be the fastest treatment option already available."
I could not agree more. So yes, this product (and ones like it) are the real deal.
