Brown Recluse Spiders are small spiders and their average length ranges between 6 and 20 mm (0.24 and 0.79 in). The distinctive feature of the brown recluse spiders is the presence of a violin-shaped dark mark; it is located on the dorsum of the cephalothorax. They are also known as fiddle-back spiders because of this violin-shaped mark.

These are small, non-hairy spiders and they bear light-brown or yellowish-brown color. Their legs are 1-inch long and contrasting to other spider species, brown recluse bears uniformly colored legs and abdomen. Unlike other spider species that have eight eyes, brown recluse spiders have six eyes.

Behavior:

These spiders have unusually high reproduction rate; a single spider lays around five egg sacs and each egg sac contain approximately fifty eggs. Thus a couple of spiders can turn into a severe infestation.

They put up haphazard, small webs near grounds and instead of using them to catch preys; they only use them for retreating. Brown Recluses are nocturnal and feed on small bugs like crickets and cockroaches.

They are shy species and aren’t known for biting humans, but if disturbed or feel threatened (like if accidentally you step on them), they may bite people and inject venom.

Signs:

The most evident sign of a brown recluses’ invasion is sighting the spider itself. Spotting a web near the floor also hints to their existence in your place. Their bites are painless initially and symptoms appear after several hours; common symptoms include fever, nausea, restlessness, and lesions. In rare cases, they are known for causing serious tissue damage.

These places are least disturbed or cleaned and thus provide them an essential habitat to thrive. They can also hide in barns, sheds and garages outside.
