Which spiders in the UK are dangerous?

Answer 1

If you mean by biting you, then no.

About a dozen species of spider have been known to bite people in the UK. Bites are rare, and the people bitten have usually been handling the spider roughly, or have alarmed a spider that had crawled into their clothes or bedding.

Spider bites are often painful, and sometimes become infected, but they are no more dangerous than bee or wasp stings. This includes the False Widow Spiders that caused a big fuss in the media recently.

If the person bitten is allergic to spider venom, which is quite rare, they may need hospital treatment, but I don't think anyone has actually died from this in the UK. This makes British spiders somewhat less deadly than peanuts.

Answer 2

A spider bite is ALWAYS dangerous if you're allergic to spider venom.

However, there are really only a few species to really look out for. there are ones in the widow family. these will be dry bites 15% of the time, meaning no venom will be injected. but the other 85% will have some degree of venom. the venom is akin to a neurotoxin and will cause the bitten to have cold and hot flashes, extreme headaches and muscle aches, trouble standing, motor problems, and difficulty breathing. however, try not to give in to the lure of antivenin. if you are given the antivenin shot when you're actually capable of pulling through and not having your vitals bottom out in the day or two it takes to course through your system, you'll waste your one chance to use it. this means if you're bitten by a more poisonous spider or a rattlesnake, antivenin will be useless on you.

If you're bitten by a brown recluse, you'll be very unlikely to feel the initial bite. however, up to eight hours later, you'll notice a sore bump in the spot you were bitten. the skin on the bump will start to turn black. this is the beginning of necrosis, meaning flesh death. the only thing they can really do for you is give you dilopsy, a medication used on leprosy patients. some doctors feel cutting away the dying flesh is detrimental to the healing process. you just have to wait until the sore is done forming and ride out the pain.

For other spider bites, be sure to ice it down. this slows the body's absorption of anything they may have tried to inject you with. it also keeps you from playing with the site and accidentally infecting it with staph or any number of other common infections. IF YOU START TO FEEL NAUSEATED OR WEAK, or your bite is doing funny things like becoming a giant pus factory, has dying skin, etc, get to a MAJOR HOSPITAL. only major hospitals will carry antivenin if you actually end up needing it.

Answer 3

Yes, but out of 640 species of spider in England only 12 of them are not able to bite. The bite causes about the same amount of pain as a wasp sting. I'm sorry but I only know the names of 3 of them, these are the most dangerous in england. The most dangerous is the false widow spider however this is mainly found in southern England, the second is the woodlouse spider and the last is the cave spider.

Answer 4

All spiders are poisonous - they kill prey by injecting it with venom (which also serves to liquify the prey's internal organs, allowing the spider to suck out the juices). However, no British spider poses any threat to human beings - even the really big ones. Some people - myself included - have reported a slight feeling of numbness in the immediate area of a spider bite but this will pass quickly. I once caught a particularly large example of a common house spider (Tegenaria duellica or gigantea) which sank both its fangs into the tip of my thumb, raising two tiny drops of blood similar to those created by a pin. My thumb was sligtly numb for a couple of minutes, then developed a pins-and-needles sensation before returning to normal within ten minutes.
