Most of the spider species are harmless to humans as their venom is not powerful enough to take a human life. Humans consider them pests simply because of their eerie-looking features, and their bizarre web building ability as well as their cobwebs.
Spiders normally feed on insects and even other spiders as well. They feast by secreting saliva on their prey, breaking them into digestible substances before consuming them. Their copulation is fatal as the female spider will devour the male spider after mating.
