You can't get rid of either type. In October the lady bugs swarm your house and the stink bugs are right there with them. Looked up one day and my house was a sea of dots, lady bugs... Can't figure out how they get in my Anderson windows, they are never opened but that's where they are.
Thousands of them, and no they all don't come in your doors when you open them. Tried the spray from Tractor Supply, didn't work.
The only thing that will eat them is chickens. So what would be worse, lady bugs or chicken poo all over the place to step in?
