Spider Bites: Symptoms and Identification

Last Update: 21.01.19

As a rule of thumb, spiders do not attack people. They don’t want anything to do with us. They come to our houses because there are shelter and food. There are over 600 spider species in the UK, but however scary this may sound, the fact is that less than a dozen of them, pose a threat to humans. Spiders are in every house, in every shed, in every attic or basement, in garages, etc. Don’t worry not all 600 species can be found in your home. There are a few that would rather come in your home than live outside in the woods. But you can encounter some of the outdoors spider species while you’re taking a walk in the park.

Unlike most insects that are considered pests and come out only during certain seasons, spiders are in your home all year round. They don’t hibernate in the winter and wake up in spring to come to your house again. At Panther Pest Cotntrol, we usualy deal with infestation from common house spiders.

However, it’s not unheard of spiders biting humans. It happens when the spider feels threatened. You should know what a spider bite symptoms are in order to identify your bite mark and treat it with the right ointment.

Which spider bites are dangerous?

Spiders do not transmit diseases to people. The truth is that spiders are not particularly dangerous to creatures bigger than them. The species that are indigenous to the UK, do not attack unless threatened. In fact, most cases of spider bites occur by accident, when a spider finds itself trapped by a human or a near a human who’s moving rapidly. Then the spider enters in a defensive mode, as all living creatures do when they feel a threat, and they bite.

Luckily for us, spiders are too small and not nearly strong enough to do big damages if they bite us. They don’t have strong enough fangs to pierce our skin deeply. As a whole, spider bites are not harmful to us and do not require special treatment or product to take care of them. They usually last for a day or two, and the pain, if there is any, lasts no more than a couple of hours. And on occasion, they can grow into minor infections or not so minor in allergic people.

However, it’s important to know what spider bites look like, because often times you may not see or feel the spider biting you, and only see the bite mark. Then, you will have to able to differentiate what has bit you so you can apply the right relief method.

How to identify spider bites?

The most common spiders in UK homes are the House spider, the Missing Sector Orb Web spider, the Lace spider, Daddy Long Legs, the Zebra Jumping spider, and the False Widow.

Out of all the spiders that could bite you the Black Widow spider and the Brown Recluse spider are the most dangerous ones, but luckily for us, there are no Black Widows in the UK. There are only False Widow Spiders which are not nearly as dangerous as the Black Widow.

What happens when a brown recluse spider bites you?

  • swollen and red
  • you feel pain in the are anywhere between 2 and 8 hours
  • you may even feel pain or stiffness in the joints
  • nausea and vomiting are also rare symptoms
  • you may develop a skin rash or fever

What happens if a house spider bites you?

This is also an unlikely scenario, but if you suspect that you were bitten by a spider here are the following signs:

  • a white bump with redness around it
  • itchiness is more likely than pain
  • you may feel pain if you scratch it too much

Spider bites when to see a doctor?

Severe signs and complications from spider bites can send someone to the hospital. From all of the UK spiders that could bite you, The Brown Recluse Spider bites are probably the ones that are most likely to cause complications and require special treatments and even medical help.

Signs you should go see your doctor are:

  • Swelling of the bitten area instead of local relief
  • Feeling nauseated
  • Having a heavy chest, difficulty breathing
  • Vomiting
  • Fast heart rate or anxiety
  • Swelling of the face/mouth/ have difficulty swallowing

Which spider bites are deadly?

The most dangerous spider in the UK would be the Brown Recluse Spider, whose bite could cause serious issues but deaths from this spider’s bite are extremely rare. Even though there are a couple of reported cases of deaths in the UK and in the USA, it’s unclear why exactly the spider bite leads to a fatal end. A couple of the reasons doctors mention are the weak immune system and the amount of venom the spider has released in its victim, and probably the late treatment. Because people tend to not take seriously such an insignificant thing like a spider bite, if they can’t tell the spiders species, of course.

There are many deadly spiders in the world, but they are not found in the UK. This does NOT mean that you should neglect your spider bite if you get bitten. You can never know if you are allergic to its venom or not, or if the wound gets infected. Pay very close attention to it and if you start feeling any of the above-mentioned symptoms, like nausea, muscle pain, fever, etc. seek medical help right away!

What to do if a spider bites you?

If you experience some pain and itchiness locally to the bite, you can relieve them by:

  • First, wash the bite with soap and water to clean it.
  • Second, apply an ointment, antibiotic if you have any. This is a must if you suspect that you were bitten by a brown recluse spider.
  • Third, if you still feel some uneasiness, apply a cold compress. It will also help reduce swelling.
  • Fourth, if you were bitten on your arm or leg, elevate the limb.
  • Fifth, if your pain threshold is low and you still feel pain after the initial steps, you can take a pain reliever.
  • Sixth, closely observe the bite mark, the area and any other symptoms that you feel in the next couple of hours.

Kids can also get bitten by a spider, you should educate yourself on a first-aid guide for parents, so you can take measures quickly.
