Spiders are segmented arachnids that have eight legs. They also have two appendages near their mouth, the pedipalps, with which they grasp their prey. They are nocturnal and hunt by injecting digestive fluids into their prey. Although they do not build webs, all spiders produce silk, a strong protein fiber that allows them to climb and cling to their prey. Despite their appearance, spiders do not have wings.
While many spiders are harmless, some can be dangerous. Yellow sac spiders belong to the clubionid family. Their venom is highly poisonous and can kill a human in as little as fifteen minutes. They are common indoors and are often found in cluttered areas.
Venomous spiders are dangerous to humans. Venom is a substance that a spider uses to overpower its prey and partially digest it. Certain types of spider venom can be extremely toxic and even deadly to humans. The Sydney funnel web spider is the most venomous spider in the world. It is found only in Australia and is restricted to a 99-mile radius around Sydney. The male of the Sydney funnel web spider is six times more venomous than the female.
The most severe form of spider bite, called a necrotizing ulcer, takes months or even years to heal. It leaves deep scars on the skin. This type of wound most often occurs during dressing when spiders become entangled in clothing, such as a pant leg or sleeve. The bite usually occurs within two to eight hours, and the pain worsens within 12 to 36 hours. A few days later, the spider begins to form necroses.
It is important to use a spray to kill the venomous spiders, especially if they are spotted near homes. If you are afraid of spiders, it is best to stay away from them. It is recommended to avoid contact with them and their environment.
The color and shape of spiders can vary greatly. Most of them have furry skin and can also vary from one species to another. Some spiders like the tarantula are quite large. Others are very tiny and require you to look closely to see them. Some start out very small and eventually grow larger when they are fully grown.
Unlike other creatures, spiders do not bite people often and most spiders that bite people are too small to penetrate human skin. Those that do bite humans in some cases are not aggressive enough to cause serious harm. The only species that is poisonous is the false widow. So remember that a female is more deadly than a male.
A mouse spider, for example, is not aggressive but can bite a human. The best way to get rid of spiders is to prevent them from entering your home. Use chicken wire on all doors and windows to keep them out. Also consider using insecticides to eradicate the pests from your home.
Despite the fear of spiders, it is important to know that they are an important part of the ecosystem and serve as food for some birds and lizards.
