Giant spiders only start spawing after the player has reached 20% of the level's total depth. This mark is usually around the beginning of the 3rd earth level. It's also usually when the player get the "Explore deep down" task done. If this task has been accomplished, spiders will certainly start appearing.
Giants spiders have three growth stages. They all have the same status though - health, speed, attack, etc.
Bigger spiders will only appear on larger web sets, already built by smaller spiders.
A new web piece will be built every 40 seconds.
No matter the distance from the spiders, if a dwarf remove one piece of a set of web, all spiders in this web set become immediately aggressive towards this dwarf.
Starting a new world, avoid digging around the 3rd level of earth, where you usually can find silver. This is where you shouldn't go before you have weapons and armors to deal with spiders as they were nothing.
Inside the shelter, use pets to deal with spiders. If a spider appear inside the pet house influence radius, the pet will run and try to kill the spider. It will only get to do so, if the pet can reach the spider. Very tall rooms isn't suitable for this.
In the mining places, limit the spiders' hability to spread their webs, by building 1 block large tunnels with torches and ladders in regular intervals. The more space you give them, the worst.
