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. A decent partner pool 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
Breed Spinarak easily with 50 breeding partners from the Bug egg group. Pass egg moves like Disable, Lunge, Megahorn and 2 more to offspring.
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.

The natural movepool does the job, but Disable and Lunge from the egg pool give Spinarak something extra. Pair those with Megahorn and Sludge Wave for STAB and coverage across 7 types for reach, and the kit fills out nicely.

Swarm strengthens bug moves to inflict 1.5× damage at 1/3 max HP or less — that's the one you want on Spinarak. Sniper is the hidden ability. Niche, but it has its uses. Insomnia works too if your team needs something different.
Spinarak is leaning toward the physical side (base 60 Attack). Fragile — can't afford to take many hits, too. But the speed tells the real story — base 30 Speed is low. Priority moves or Trick Room are the way to go.
