This is an assassin bug called the "masked hunter," Reduvius personatus. The species is native to Europe and northern Africa, but has been established on this continent for some time now. Nymphs cover themselves with debris, hence they are "masked." Adults like this one fly well, and are often attracted to lights at night. I might be tempted to check for bed bugs if I were you, as that is the favored prey of this insect. Also, you do not want to be bitten by one of these. The bite is excrutiating, though not life-threatening, fortunately....Simply usher any more of these into a container and release them outdoors.
