How Old Are Big House Spiders?
WouterGiant house spiders were first introduced to southern British Columbia around the early 20th century. It is thought that they were transferred into the area by people moving household goods. Since then, they have flourished in the Pacific Northwest, Washington and Oregon.
These spiders are considered to be very harmless. They are mostly found inside buildings, in bathrooms, garages and sheds. They build large sheet webs with an exit funnel. They are also known to live outside in warmer climates.
Like most spiders, they eat insects. They are predators, but not very aggressive. They will only bite if they feel threatened. If they are disturbed, they will often leave a tangled web of silk.
These spiders are considered to be beneficial pest eaters. They are particularly active at night, where they hunt for prey. They can be found in houses, basements, baths, showers and even attics. They can sometimes get stuck in bathtubs or basins. If you see a large spider, wave at it as it moves past.
The average lifespan of a spider is one year. However, some species may live longer. The tarantula, for example, can live up to thirty years. Other species such as the common barn funnel weaver can live for up to seven years.
The lifespan of a female house spider is considerably longer than that of a male. She can stay with her mate for several weeks. During this time, she will have an egg sac that contains fifty to sixty eggs.
