A family in Kansas unknowingly cohabited with over 2,000 spiders for five years, with approximately 400 of them being venomous brown recluse spiders. Although some spiders are beneficial, others pose significant risks. The discovery of the venomous spiders shocked scientists.
The family had sporadically noticed spiders in their home, but it took five years for them to realize the presence of venomous brown recluse spiders. Upon contacting pest control, all the spiders were captured. Surprisingly, none of the family members had been bitten despite the long cohabitation.
Brown recluse spiders are venomous, but their bites typically result in temporary blistering or swelling that subsides within a week. Once these spiders infest a home, they are challenging to eradicate as they hide in furniture and unnoticed crevices.
These spiders can survive without feeding for months, with females needing only one mating to reproduce throughout their lives. The family only became aware of the spider infestation in 2001, despite living in the house for over five years.
After pest control identified the spiders as brown recluse, a total of 2,055 spiders were captured in six months, mostly categorized as small spiders. It is believed that many of the small spiders were juveniles, as brown recluse spiders are non-venomous until they reach around 5mm in size.
A study published in the Journal of Medical Entomology indicated that the home likely harbored around 488 venomous spiders. Astonishingly, despite the high number of venomous spiders, the family remained unharmed.
The study highlighted that despite the presence of potentially harmful spiders, no bites occurred. Similar cases in other regions suggest that misdiagnoses of spider bites are common, leading to overestimated severity. Doctors may mistakenly attribute dermatological issues to spider bites in areas with limited spider populations.
