Vermin: Why you need to have the tarantula in your home

The trembling spider is one of the most delicate and filigree spider species you can find in your home. With its small body of only 8 to 10 millimetres and extremely long, thin legs that reach a wingspan of up to 7 centimetres, it looks very fragile. Its legs look almost like thin threads that sway slightly when it moves. Its coloration ranges from light brown to grey, and its delicate appearance makes it easy to overlook in dark corners.

Danger of confusion

Due to its long, thin legs, it is often confused with the weaver spider. However, unlike the latter, which is merely an arachnid, the trembling spider is a real spider and therefore has the ability to build webs.

Trembling spiders often build their webs in the corners of rooms, on ceilings or behind furniture. Their webs are rather irregular and not as elaborate as those of other spider species. In case of danger, the trembling spider shows a unique behavior: It begins to tremble strongly in its web, which is intended to confuse potential attackers. This trembling behavior also gives it its name. Trembling spiders are harmless and very useful, as they catch insects such as mosquitoes and flies and can even eat smaller spiders.

Habitat and distribution

This spider loves dry, warm and quiet places, which is why you will often find it in living rooms, basements or attics. It can nest unnoticed, especially in rooms that remain undisturbed for a long time, such as storage rooms or rarely used rooms. Due to their preference for dry conditions, they are less likely to be found in bathrooms or very damp cellars.

The trembling spider is widespread in Germany and can be found in almost every household. You will often only notice them when you discover their web or they give themselves away with a sudden movement. It is a frequent guest in German homes, especially in the colder months when it retreats indoors to escape the cold.
