Almost nobody uses Spinarak in battle. It exists to evolve into Ariados, which is a completely different story. Get it there and you won't regret it. Only weak to Fire, Flying, Psychic, and Rock. Known as the String Spit Pokemon.
Nothing fancy in Spinarak's spread. It leans mixed with Attack out front. And you'll get 1 Attack EV per KO for it. Follows a fast 800K XP curve.
It sets a trap by spinning a web with thin but strong thread. It waits motionlessly for prey to arrive.
Spinarak Weakness
AvgSpinarak's Bug/Poison typing leaves it vulnerable to Fire, Flying, Psychic, and Rock moves. The Bug/Poison typing picks up 5 resistances to work with.
Spinarak is the base form in a two-stage line leading to Ariados. Check the evolution method below. Plenty of partners for breeding via one egg group. Eggs are quick to hatch. The evolved forms gain up to 150 total stats over Spinarak.
How to Evolve
Swarm isn't flashy, but it matters. Combined with Scopelens for extra utility and a spread EV build EVs, Spinarak fills the hazard lead slot reliably. Adamant nature finishes the spread.

Egg Moves
Tutor Moves
