In brief: Bed bug bites may

Cause no sx's or signs in some except for 2 small points where skin was punctured by bedbug.
When there's a reaction, it may not show for several days after being bitten. It can cause itchy, pink, swollen, lesions which are clear in center. In cases of hypersensitivity blisters may develop. A telltale sign is a linear track of lesions from sequential feedings – but that doesn't always occur. Bite.

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.
