Acid spiders are insects that live in warmer areas south of Kanto and can be found in a wide area such as Kanto, Kansai, Shikoku and Kyushu regions.It is nocturnal and rarely moves in bright places, but becomes active at dusk.
The body size is 25-30mm for females and 15-25mm for males, and many individuals are more than 100mm with their long legs spread out.
The color of the body can be clearly distinguished because it is a large spider.Overall, it is grey-brown, covered with white, ash and brown fur.If it is stuck to the ceiling or wall, you will find it soon.
The average life expectancy is about three years after overwintering, and if left unchecked, it will appear indoors throughout the year.
How to tell a spider from a spider
A similar-looking spider called a “co-tailed spider” also exists among the spiders.The habitat is almost the same as that of a reed spider, so you may find both spiders at home.
The spider can be distinguished by two points: its size and its body pattern.The spider is about one size smaller than the spider and is often found outdoors.Females are 20-25mm, males are 15-20mm, and there is a yellow triangular pattern on the back hip.
If you found a “big spider with a pattern on its body” in your house, it is highly likely that it is a coacid spider.
Large-bodied spiders do not bite people unless they carelessly touch them, but rather have the aspect of being “a beneficial insect.”A beneficial insect is an insect that has habits that are useful for daily life, such as pollinating crops and eating pests for people.
The spiders feed mainly on cockroaches, moths, flies and crickets, which come into their homes from outside looking for food.
Among them, cockroaches are pests with pathogens that threaten human health.They are called beneficial insects because they kill cockroaches instead of humans.
Also, sea spiders do not make webs out of thread as is common in spiders, so you don’t have to worry about being webbed even if you leave them alone.People who are suffering from harmful insects such as cockroaches and flies should dare to leave the spider unattended.
