Talk:Spider Den/@comment-39421695-20190524190706

Keep in mind that Spiders leave Dens at Dusk/Night, and attacking a Spider will cause all other Spiders within a couple screens to aggro. This means if you've aggro'd a Spider at Dusk/Night in a biome packed with Dens, dropping a Trap in its path is far safer than attacking it.

I try and destroy every Spider Den in the world (except one) within the first Autumn, while they're still all Tier 1 and super easy to deal with. If I encounter any Tier 2 or 3 Dens, I usually set fire to them (preferably via a nearby tree) to save time.

Homeless Spiders (even Warriors) can easily be dealt with during the Day (when they're sleeping) by dropping a Trap directly on them. Attacking them is less recommended because others nearby may awaken and aggro.

If you end up accidentally exterminating all the Spider Dens in the World, you can use Moon Rock Idols to switch briefly to Webber, who comes with Spider Eggs and can craft more.
