So i found out that my yard is infested with ground bees. There's about 40 holes, probably more. But most sites that i've visited say that there are only a few holes with ground bees. I want to just pour some hot waters over the holes and get rid of them, but I'm afraid that the job may be too big for just me and require an exterminator. Can I get some insight?
Also, the bees are black with yellow stripes on their abdomen and I live in western NY, if that helps.

tldr: ground bees everywhere, help
