How to Recognize the Violin Spider and What to Do in Case of a Bite

Known by its scientific name Loxosceles rufescens, the violin spider is becoming one of the most medically significant spiders in Italy. The perception of risk associated with its presence in homes and human-inhabited environments has recently increased due to the numerous reported cases.

Biological Aspects and Characteristics of the Violin Spider

A small spider (about 9 mm body length and 4-5 cm leg span) with a light brown color, it is easily recognizable due to a violin-shaped mark on its prosoma (the front part of its body) and its six eyes arranged in three pairs, instead of the typical eight found in most spiders.

Originally native to Mediterranean regions, it has now colonized the entire Italian peninsula, including urban areas. It lives in crevices and cracks, tends to be reclusive, and stays hidden during the day, becoming active at night. If it feels threatened (e.g., risk of being crushed), it may resort to biting in self-defense.

The Violin Spider Bite and How to Respond

Among the various spider species in Italy, the bite of the violin spider can pose significant medical concerns. If you are certain that you have been bitten by a violin spider—meaning you saw and identified the spider responsible—it is advisable to photograph and/or capture it and immediately contact the nearest Poison Control Center.

Lastly, if you find this guest in your home, it was likely there for a long time already. The violin spider is reclusive by nature and bites only in rare cases, such as when it is crushed or accidentally trapped in clothing or shoes.

How to Prevent the Presence of the Violin Spider in Your Home

To prevent this spider from hiding among discarded clothes or bed linens and to avoid unpleasant incidents, keeping living spaces tidy is essential. Another precaution is to eliminate potential hiding spots where it could nest, such as sealing baseboards, wall cracks, and pipe passages.

As a last resort, chemical treatments can be applied by saturating the rooms using total-release aerosol cans containing Etofenprox (Ethoshot) or fumigation with products based on Cyphenothrin (Dobol) or Permethrin (Fumikol).
