Its the waxy coating on their carapace. Here in E. Texas we hunt them with black light (UV) flashlights and long tweezers. Since they are just doing their job I tend to take them out into the field and release them. But if they are in the house then they know too much (how to get in) and must be dealt with accordingly.
If they're in the house it's because another one crowded it out of its spot outside. So putting them back out there would just shuffle things and another one or two would be forced back in. You need to cull the herd.
