Mystery Yellow Balls in Potting Soil: They're Fertilizer Pellets, Not Spider Eggs

Jen found clear yellowish round things (1–6 mm) in Miracle-Gro soil and new plants potted with it. Bag had small holes. Balls are liquid-filled, release white/gray liquid when popped. Thought they might be spider eggs.

Will Creed identifies them as timed-release fertilizer pellets. They absorb water and slowly release nutrients. Hard shell, squish when popped, liquid release is normal. No spider infestation risk.
