Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Mga fact

A male plucks the female's web to attract her attention before he approaches to mate. They may stay together for several days and mate several times.1

The spider rarely moves its web, so old webs become messy, with dust and small objects stuck in them.1

At night, the spider repairs and adds to its web, often by laying new silk over the old.1

The female almost never leaves her web unless she is forced to.1

Predators include the white-tailed spider, as well as parasitic wasps and flies.1
