Masked Hunter

6134   Hi.  This bug was just inside my house in Nova Scotia. Is this a form of tick?

This is a masked Hunter. Both adults and nymphs are predators that feed on other insects including flies, carpet beetles, mealworms and bed bugs. The adult bug is dark brown or black and about 3/4 of inch long. The nymphs or immatures are covered with microscopic hairs which catch and hold dust, lint, and other small particles of debris.
