There's lot of those black and yellow fuckers on my house. They keep there in their love nest.
Who should I call?
I don't have any of those. Maybe poking them with a stick?
Look like Mesquite Bugs. They emit a strong odor when threatened so be careful OP.
Rip in piece afeiçoado.
But seriously though just spray them down with some toilet spray or other strong chemical.
If you use a toilet air freshener it will also take care of the disgusting stink they will shoot out of their asses when they sense danger.
