Bed Bug Bites vs. Mosquito Bites: How to Tell

How to Identify Bed Bug Bites

Waking up with itchy red marks can be alarming. Are they from a mosquito or bed bugs? There are clear differences that can help you identify the cause.

Patterns Are a Key Clue

Bed bug bites often appear in lines or clusters. Mosquito bites are random. Exterminators call the bed bug pattern "breakfast, lunch, and dinner."

Where Bites Appear

• Mosquitoes: Bite exposed skin. Usually on face, arms, or legs sticking out from blankets.
• Bed Bugs: Can crawl under clothing. Bites may appear on stomach, back, or covered areas.

Reaction Timing

Mosquito bites itch immediately. Bed bug bites may take hours or days to appear because of anesthetic saliva.
