Spiders have evolved surface chemistry (oil on their bodies or legs)that enables them not to get stuck in their own webs. The oil is slippery, so the web won't stick to it. But most spiders do tend to get stuck in the webs of other species, especially if they're very different groups of spiders
Not all of the treads in a web are sticky. Spiders first spin vertical threads, which are not sticky, and then horizontal threads, which are. Insects get caught when they touch the sticky threads, but spiders "tiptoe" over them.

Hi. The spider web has droplets of goo that are sticky. They must be able to step around them. Either that or all of the spiders who did get stuck would be extinct.

Excellent question and neat answer: because they leave certain strands unsticky, and only they know which ones are which, but insects and even other spiders do not. So - opps! There goes another bug, stuck in the web.

Because only certain strands are actually sticky and the spiders know which ones are and aren't so they can safely maneuver across the web as they get their prey.

It steps on the parts of the web that aren't sticky.

Well they're not likely to build a trap that will trap themselves are they? They spin webs to catch food and irritate me when I walk into them!

the itsy bitsy spider does not want to be food for another spider.
