if most house spiders eat insects why do they bite humans?

Answer 1

cuz peter parker controls them

Answer 2

Let me just clear up something right away before i start to give the real answer to this question.......

Spiders do not bite humans for no reason, for some reason people still believe that spiders bite people in their sleep....This is completely false!!!
Spiders only bite people if they are mishandles, threatened, or in some cases if their webs are disturbed. Spiders are not parasitic in any sense, they do not feed off the blood of humans, or any other animals for that matter. ALL spiders are predatory, they will kill and consume the predigested intestinal soup of their prey

They do not suck blood, or lay eggs on people, and we do NOT eat a certain number in our lifetime....all of these are rumours going around, that severe arachnophobics create......

There is no scientific evidence of any of these events occurring to anyone anywhere!!!!!

Spiders will hunt and kill living organisms smaller than themselves, this includes insects, other spiders and even vertebrates if the spider is large enough.
I hope this answers your question, and hopefully alerts some people to the very common misconceptions about spider behaviour!

Answer 3

the respond relies upon on which u . s . you reside in, because of the fact the call "daddy longlegs" can talk with distinctive creatures in distinctive worldwide places. interior the united kingdom, a daddy longlegs is in many cases a crane fly (Tipulidae) - an insect, not a spider. interior the USA of a it always refers to a Harvestman (Opiliones) - which has 8 legs yet isn't a spider the two, technically. In Australia and NZ it always refers to a cellar spider (Pholcus Phalangioides). I say definitely because of the fact even interior an identical u . s ., some human beings use daddy longlegs to intend the insect and human beings mean the spider or the harvestman. besides the shown fact that, all 3 are probability unfastened to people. The cellar spider can bite yet its venom is so vulnerable it won't be able to harm you. The crane fly would not consume bugs or spiders. The Harvestman eats bugs, yet not spiders. The cellar spider besides the shown fact that eats the two bugs and different spiders, even greater ones than itself.

Answer 4

All animals have evolved methods of self-protection, and the spider is able to use its fangs both as defense as well as obtaining food. There are many thousands of species of spiders and while some enter houses, all species live where they can find food so all types could be considered house spiders, and if they are threatened, they bite. I have been bitten by a recluse spider while sleeping, so apparently the spider crawled on me and I moved or did something that made it afraid and it bit me.

Answer 5

They get hungry and expect you to die after biting you so they can start eating your carcass, then save the rest for later by encapsulating it in spider silk. That's their plan, anyway.

Answer 6

not the house spiders,only the ones in the jungles

Answer 7

Maybe your house spiders are telling you they are hungry.

Answer 8

Usually they don't!

They MIGHT bite a person if they feel threatened.

Answer 9

Answer 11

to defend themselves ( they feel threatened).....they bite when they are cornered or pinned against something.
