A reaction may show from an hr to several days later. It can cause itchy, pink, swollen, lesions w clear center. If hypersensitive blisters may occur. Telltale sign is linear track of lesions from sequential feedings – doesn't always occur. Bites are in areas exposed while sleeping-arms, shoulders, neck ; legs. Signs of secondary infection.

bedbug bites cluster; mosquito bites do not.

In brief: See below

Most insect which draw a blood meal though a bite will cause a local reaction with redness, swelling, warmth and itch.
It is often impossible to tell these apart, but bedbugs will often leave a straight line or repeat bites whereas other bugs like mosquitos, fleas, etc. May look scattered. However, there are treated in the same way - wound care, steroid creams and antihistamines.
