I am not an expert, so do not take what I say for “should I let this thing bite me”, but in Washington and the UK we have “giant house spiders” that look just like this (to my non trained eye). They are terrifying to find, but harmless generally. Leave very waxy webs.

If that’s the case, just start putting out some sticky traps in your home, wherever you find one just throw a trap down. Warmer years brings more of them
