Exact Answer: 1 To 2 Years
House spiders are found throughout the world in most habitats. House spiders are a common household pest. Although they can be scary to see, these creatures don’t pose much of a threat to humans.
Most house spiders live for about one year in an indoor setting. However, their lifespan may vary based on the type of spider and the conditions in which it lives.
They are mistaken for common house flies because they have similar coloring and body shapes. However, there are many differences between these two insects that can help one identify them easily as spiders have small, simple eyes on their head.
How Long Do House Spiders Live?
| Type | Duration |
| House spiders | 1 to 2 years |
| Wild spiders | 2 years |
House spiders can live anywhere for about 1 year. Their lifespan is determined by external factors, such as food supply and the web decorations inside their nest. Corpse hunter spiders have a span of 1 year or less because they eat dead animals found outside the nest.
A house spider’s lifespan is limited by many factors, including temperature, the availability of prey, and the abundance of shelter. Often this results in a year lifespan because these conditions are not created to support their basic needs.
Although it’s rare for a spider to reach its actual life span (3 years), the fact that they die so quickly means there is one less critter inside one’s home plaguing the residents with allergies and fears.
House spiders are a special type of spider that will create webs in protected locations such as the corners of the room they live.
House Spiders can catch insects and other creatures that fly, jump or crawl into their webs. The captured prey might then be eaten as food or as an act of protection as these spiders can eat many individual insects in a period between six and seven months.
They do not kill their victims before eating them because this would cause dismemberment and damage the webbing.
There are also reports that they can live up to seven or 30 years if the living conditions are ideal. Sometimes a curious lizard, cats, and dogs can bring an end to their life. It is also true that female spiders tend to live longer than their male counterparts.
Why Would House Spiders Live For So Long?
The lifespan of a house spider has been linked to environmental stressors, such as the availability of food and shelter.
The typical lifespan for a house spider is anywhere from one year to several years, and this lifespan depends on where the spider lives and its diet.
However, if a spider lives outdoors in an area that can provide lots of insects, it will likely live for at least two years.
If the same spider lived indoors near people being killed by pesticides, it might die within a few months because there are no other spiders or bugs to eat besides those sprayed with poisonous chemicals.
House spiders are scavengers who eat anything from captured prey to insects, refuse, seeds, fruit peelings, fungi, and sometimes even other spiders.
House spiders are tarantulas found in homes worldwide because they are hunters of small animals that live around human habitations.
They live an average of one year because they die before winter and don’t survive the cold winters outdoors. Those lucky enough to survive this first year will survive another five years or more.
If one removes them from one’s home at the first sign of their presence, chances for getting them out alive can be increased dramatically.
Also, house spiders live alone to have a better chance at catching prey. They are also not territorial or aggressive, and they do not need to eat daily to survive, but they do eat a lot if the food is abundant.
Conclusion
Overall, house spiders have a short lifespan, and humans tend to use pesticides a lot to kill insects. Most of the spider’s time is spent waiting for the prey to get stuck in its web. Larger species of spiders tend to go without food for as long as 30 to 60 days.
Even baby spiders can survive without food for a long time. The common food of the spider are flies, mosquitoes, moths, ants, gnats, cockroaches, crickets, earwigs, centipedes, and many more. Access to water is also very important for the spider to survive, and they drink from condensation, dewdrops, and leaky surfaces.
