Fly Bites
Many types of flies may bite humans, such as black flies, stable flies, horse flies, or deer flies. In most cases, fly bites tend to appear as red, raised welts or bumps. Some would even bleed or cause swelling. However, the symptoms tend to improve over time and do not cause any serious complications. In some rare cases, blackfly bites may result in a flu-like illness known as blackfly fever, and deer flies may transmit tularemia, a bacterial condition. [7]
Tick Bites
To identify a tick bite, the simplest way is to look for the insect attached to your body. These insects tend to stay on humans for 3 up to 6 days when they feed on the blood. The affected areas may appear as red spots with the size of a dime. There should be no pain, but you would feel itchy at first. Tick bites usually happen on warmer sides of the body, such as the groin, behind the knees, armpits, and hairline. [8]
