See now they are making YOUR home a living hell. You can not kill them you made this mess, they have a right to live. Really the best thing to do was to leave them alone in the first place, but now they are your responsibility because you made this mess and when you made them homeless they moved in next door (your house)
How about this find a better place for them to chill, close by. Like another similar tree, or a old log something they can LIVE in cuzz you did make them homeless. Put some food over their for a few days/week and I bet they will gladly move to their new improved home, and not bother you or haunt your dreams.
