It can be somewhat difficult to identity a brown recluse infestation because they are nocturnal and try to avoid humans. If you have seen and identified a brown recluse around once a week, it is a good idea to take action against an infestation. Inside homes, brown recluse spiders are usually found in dark places, such as in seldom used clothes, cracks, corners, and inside furniture. Outside, most are found in piles of wood, under rocks and in hollow trees. You should take special care when gardening because it is possible to disturb a habitat of a brown recluse.
