How come some mosquito bites are filled with pus?

The mosquito is a common, painful, and annoying insect type. They look like flys but thin and smallwoth sharp pokers that may poke through your skin when bit. The mosquito leaves saliva in your skin which causes pus because of the blood and pus collision which is why you should never pick scaps or squeeze or put pressureon the bite. Pus is normal because usually it forms on a bite when the mark the mosquito made is being healed or if any case, getting rid of the bacteria and infection. This is why pus may form in a mosquito bite if you notice it. Make sure t heal and take care of the bite and do NOT irritate the bite so it does not get massively bigger and infected.
