Harmless

We also have quite literally, thousands of them around our place this year - finding clumps of them in several places daily.
For what it's worth though, other than being a bit of a nuisance, they're harmless. They don't bite or sting, they don't do damage to property/wood/trees/structures at all. They feed on the sap and/or seeds of box elders, maples, etc., but no noteworthy damage to the trees themselves.
So other than a bit of a creepy "ick" factor, nothing to worry about really! It'll be winter soon enough, and you'll forget they were ever here! ;-p
