I found 3 of those inside my house, on inital research it points that they are eastern yellow jackets and with the dots, they are queens, but what are the odds of finding 3 queens in 3 days?

We believe the markings on these Yellowjackets are a closer match to the introduced German Yellowjacket Queen pictured on BugGuide. Each fall, a nest of Yellowjackets produces multiple queens that mate and find a place to hibernate over the winter. If your house was the nearest possible location for hibernation, and if it was especially inviting as well as providing an entrance for them, it is very possible that more than one queen would seek out your house as a potential site for hibernation.
