The Terrifying Giant Crab Spider Often Enters Arizona Homes Where They Spread Into Rooms Via Ventilation Ducts

You don’t have to be a resident of Arizona to know that many scary-looking spider species are abundant within the state. Most arachnophobes consider tarantulas to be the most fearsome spiders that exist. Although Arizona is home to 30 tarantula species, none of them are particularly large in size. The most colossal tarantula species on record can be found in tropical regions of South America, Africa, Asia and Australia. It should also be noted that one of the largest spider species that exists in the United States is, surprisingly, not a tarantula. This spider species is officially known as Olios giganteus, but it is more commonly referred to as the giant crab spider. This spider’s nickname is quite fitting considering that females of this species have 2.5 inch leg-spans. Most spiders that grow to be as large as giant crab spiders do not climb walls or any other vertical surfaces, but the giant crab spider is an exception, as these spiders are commonly found crawling at rapid speeds across plaster walls within homes in southern Arizona. Unfortunately, such sightings are not uncommon in the southern half of the state, as giant crab spiders habitually dwell around homes, and they are not shy about waltzing indoors.

One of the most frightening aspects of the giant crab spider is their unusual habit of accessing multiple rooms within a home by traveling through ventilation ducts. But this is far from being the only unpleasant behavior that the spider exhibits within homes. For example, in addition to be large in size, giant crab spiders are aptly named for moving sideways like a crab. However, unlike a crab, the giant crab spider moves at tremendously fast speeds that make them very hard to catch. In fact, these spiders are often fast enough to successfully evade humans who simply want to kill them as quickly as possible. Crab spiders are a common sight within Arizona homes because their predatory nature keeps them mobile at all times, so they often wonder into homes despite preferring an outdoor habitat. The only time crab spiders remain still is when a female lays eggs or when the spiders hide out beneath furniture during the daytime within homes.

Would you respond with fear to the presence of a crab spider within your home?
