Multiple news outlets captured the goats calmly eating grass and shrubs in a Boise neighbourhood on Friday before a trailer arrived amid applause from residents.
Photos showed the animals gobbling their way through picture-perfect lawns as bewildered residents looked on in horror.
The goats had been corralled near a local retention pond to eat weeds and other overgrowth, but - perhaps noticing the grass was greener next door - broke through a wooden fence to roam the neighbourhood.
Kim and Matt Gabica own the animals as part of their business called We Rent Goats. They gathered the docile herd and said all 118 of the goats were accounted for.
The herd of about 118 goats was wrangled into a truck by company workers at around 8:30 am local time.
By then the goats had already built up an online following of social media users. One reporter for the local KTVB news channel dubbed it the "#Boise Goat-a-Palooza 2018."
One Twitter user said that in 30 years they would be telling their grandchildren about "the great goat invasion of 2018." Another tweeted: "They're maaaaaaaad as hell and they're not going to take it anymore," riffing on the "baaa" sound made by goats.
Goats are sometimes let loose in the nearby Boise foothills to eat wild plants and reduce wildfire threats.
