When Bees Get In

On the outside of our house between the launder room and the hill, we have bees. Bumble bees. We tried to kill them a while ago by emptying a can of bee spray into their hole and then placing a bowl over them. It seemed to work until we took off the bowl, they came back. And now they are tunneling, in the hill, in the house. But our can of bee spray is gone and you would need a dome to cover them. Well, they are coming in through the basement or at least one did. We didn't spray it or smash it with our feet but it didn't live long.
