I see people asking you to pour sniper and kerosene on it. It won't do much. You will just kill the ones on the surface. Guess what? They will be replaced. The queen lays 20,000 to 30,000 eggs per day.
Once it gets to this level, you have to get experts involved. They'll most likely dig somewhere inside the house so that they can locate the queen and bring her out. That's the real solution.
What you see outside isn't their house. It's their own walkway canopy to the "office," which they built so as to go to and fro, without being exposed.
I know it’s become pretty cliche and cringey to talk about at this point but if you’re under like 25 I cannot stress enough how one time Obama wore a tan suit and people spent a week arguing over whether or not it was demeaning to the Oval Office and they were serious about it.
