If you get a rash around a mosquito bite within 24 hours of getting bit are you allergic to mosquito bites?

Answer:

Only if you have not scratched it.
You can cause a "redness/rash" at the site merely by scratching the bite and spreading the mosquito saliva around. If the swelling spreads out past a normal size (more than 1") then it is possible you are having an allergic reaction.
