Table of Contents

Many fear a spider bite. Especially at night when the eight-legged creatures go hunting, the fear of them is great. But do spiders even bite people in their sleep?

In a nutshell

  • Spiders don't specifically target people
  • at night the animals are on the prowl
  • they sometimes get lost on beds, sofas and other sleeping places while hunting
  • if they are crushed or if they feel threatened by humans, there is a bite
  • In non-allergic people, bites are similar to mosquito, bee or wasp stings

Do spiders bite people?

Unfortunately, if you are wondering if a spider bite is possible during bedtime, then you will have to settle for a yes. Spider bites can happen overnight, especially if the animals get lost in the house. Bedrooms are not spared their presence. In Central Europe in particular, however, it is very rare that you are bitten by one of the animals at night. But why are spider bites more common in your own four walls at night? The reason for this is the behavior of the animals. They only bite people randomly, and not on purpose, when they are engaged in the following activities:

  • Foraging
  • Territorial defense
  • pairing
  • Search for a new nesting place

Note: Many species of spiders are more active during the mating season, which increases the possibility of confrontation during the night.

Causes of a Bite

As already mentioned, spiders only bite when the animals feel threatened or cannot find a way out. It is precisely this defense behavior that cannot be controlled during sleep. In addition, humans are significantly larger and this can lead to a variety of situations in which a bite is the animal's last resort. The following are to be mentioned here:

  • Animal is beaten
  • is squeezed
  • gets caught in clothing
  • is being held

Note: If you keep dangerous spider species like the Brazilian wandering spider (Phoneutria nigriventer) or Sydney funnel-web spider (Atrax robustus), you should keep the terrarium tightly closed overnight. Such dangerous species are often more aggressive, which makes an even fatal bite possible.

frequently asked Questions

What is the most poisonous species of spider in Germany?

Germany is not considered a paradise for dangerous poisonous spiders. However, there are two types specifically whose bite can be uncomfortably painful. These are the water spider (Argyroneta aquatica) and the nurse's thorn finger (Cheiracanthium punctorium). The bite of the garden spider (Araneus diadematus) can also hurt a little. They are only dangerous for allergy sufferers, but do not get lost in human dwellings.

Are there spiders that are poisonous to humans that live in houses?

Yes, the trembling spiders (Pholcidae) should be mentioned here. Due to their appearance, the species are often confused with harvestmen (Opiliones). They are considered to be slightly poisonous, but their mouthparts cannot penetrate human skin. Therefore, you don't have to worry about the animals.

What should be considered after a spider bite?

If you are allergic to insect venom, you should see a doctor or hospital as soon as possible. Therefore, pay particular attention to allergic reactions. Never scratch the wound, otherwise pathogens can get into it, which in turn can lead to infectious diseases. Cool the bite wounds to suppress the itching.
