Big House Spiders, also known as Tegenaria or common house spiders, are often found in homes and can cause quite a scare for those who are arachnophobic. These spiders, while intimidating in size, are often harmless and can even be beneficial to have around the house. Here are some fear factors and fascinating facts about Big House Spiders.
1. Appearance: Big House Spiders can grow up to 12 centimeters in leg span, making them one of the larger spider species found in homes. Their long, spindly legs and dark brown or grey coloration can also make them appear more menacing.
2. Speed: These spiders can move quickly when disturbed, making them seem like they are charging at you.
3. Webs: Big House Spiders spin webs which can be large and sticky. Walking into one of these webs can cause a fright, especially if the spider is also present.
4. Bites: While Big House Spiders are not aggressive towards humans, they can bite if provoked. Their bites are not usually harmful, but they can cause some swelling and itching.
1. Habitat: Big House Spiders are found in many parts of the world, including Europe, Asia, and North America. They prefer to live in dark, sheltered areas like basements or attics.
2. Food: These spiders are known for hunting down and eating other insects that may be found in your home, such as cockroaches or mosquitoes. This can be a helpful asset in controlling pest populations.
3. Myth: Some people may conflate Big House Spiders with the poisonous Brown Recluse Spider, but this is a myth. Brown Recluse Spiders are not found in most parts of the world and are easily distinguishable from Big House Spiders.
4. Lifespan: Big House Spiders typically live for one to two years. However, exceptionally long-lived individuals have been known to survive for up to seven years.
5. Mating: Male Big House Spiders will often drum their legs on a surface to attract a female. Once they have caught her attention, they will present her with a gift of food wrapped in silk. If she accepts the gift, the male then mates with her.
While Big House Spiders can be intimidating, they are typically not dangerous and can even help keep other pests at bay. By understanding their habits and behaviors, you can learn to coexist with these arachnids.
