What's the definitive way to determine if these itchy bumps are mosquito bites, hives or bed bug bites?

In brief: Can be tricky

There are differences btwn mosquitoes & bed bugs.
Mosquitoes usually aren't out when it's really cold & they are often found outside in wooded areas. Bug beds live inside & thus are not impacted by the temperature. The itching from a mosquito bite starts right away & usually resolves w/in a few hrs. Bed bug bites may not itch but when they do it might take up to several days for this to occur. You.

You may only have 1 mosquito bite or bites can be sporadically located whereas bed bug bites can be linear due to sequential feedings. Bed bug bites may cause no sx's/signs in some except for 2 small points where skin was punctured by bedbug. Bites are usually in areas that are exposed while sleeping-arms, shoulders,neck & legs. Hives can occur suddenly anywhere on your body. They are pink to red,

smooth textured- flat topped bumps that can be very small or large or may even coalesce. They can itch intensely as well as stinging.

In brief: Looks, Located, #s

Mosquito bites are generally just a few and follow being recently outside in the evening or night.
Bed bug bites are more commonly located on the legs & feet and may cover large areas. Both mosquito & bed bug bites will have individual punctures. Hives tend to cover larger areas and have more aof a rash appearance. When in doubt, see your md to be certain.
