how do you know if a bite is from a spider or from a mosquito?

Duration: Likely the only way to tell will be that most mosquito bites are over/done/gone in 2-5 days. Spider bites, if from "concerning" species, will get slowly/steadily worse over that time frame, w/increasing local reaction & infection risk, and should be seen by dr if worsening after 5 days.
