Spiderlings disperse by releasing silk threads that carry them on the wind.
The longer version
Young spiders leave crowded hatching sites by releasing silk threads and letting moving air carry them away, a habit called ballooning. The thread creates drag, so even a light breeze can lift a tiny body considerable distances. Static electricity in the air may add some lift as well.
Going separate ways matters because spiderlings compete for food and some species eat one another, so dispersal lowers that pressure and reduces the chance that every sibling meets the same bad outcome. Distance depends heavily on air movement and body size, with smaller ones usually going farther.
