The cupboard spider is a common house spider that lives in dark corners and builds messy, three-dimensional webs. It is often mistaken for the dangerous black widow, but its bite is usually minor. Its name shows that it is found in many parts of the world, including Europe, temperate Asia and areas where it has been introduced.1

Pas på dig selv

Rør aldrig ved, fang eller dril et vildt dyr, heller ikke et lille et, og heller ikke hvis det ser ud til at sove eller være dødt.
Giv det plads. Hvis du møder et, så bliv rolig, træd langsomt tilbage, og lad det gå sin egen vej.
Hvis et bider dig: Bevar roen, hold dig i ro, ring til dit alarmnummer (112, 000, 911), eller kom hurtigt på hospitalet. Husk, hvordan det så ud, et billede hjælper.

Det er ikke ude efter dig. Det bruger sin gift til at fange føde eller beskytte sig selv, og det gemmer sig meget hellere. Mere om sikkerhed
