Wikipedia on Homo Erectus: "[...] the earliest first fossil evidence dating to around 1.8 million years ago and the most recent to around 300,000 years ago."
Therefore it is reasonably safe to assume that they didn't survive quite much longer than 300,000 years ago, until new and younger fossils of Homo Erectus are found.
