The bite of camel spiders represents no great threat to the general health condition, unless it gets infected. The only variety of venomous camel spiders grows in India, but research is pretty scarce in the field. The favorite habitat of the brown widow spider includes well protected locations in homes and other man-made structures. You may even find brown widow nests in buckets, mail boxes, entry corners, closets, garages and even in vegetation like shrubs and tree branches. Most bites occur when one accidentally stick their hands into such secluded areas and corners or when the spider gets pressed against the skin.

The bite of the brown recluse spiders is likely to cause a whole range of symptoms at the skin level known as loxocelism, and the greatest risk they involve is that of necrosis. Most bites are not only minor but also extremely rare; brown recluse spiders do not attack unless they feel threatened. As their very name suggests they enjoy very retreated corners where they are not bothered by light or intruders: cellars, garages, hallways or any other dark house area.
