Here you go, they grow to about 1/2 an inch. By the way, majority of people just get a small painful red spot when bitten by one. They aren't aggressive at all and like to make their homes in clothes or beds that have been sitting still for long periods of time. If you have an allergic reaction to the venom your wound will erupt like the pictures above and take six to eight months to heal back to normal leaving a scar.
Sorry Jamie, changed them to links.
