Yellow Globules in Potting Soil: Fertilizer Pellets, Not Insect Eggs

Clear/yellow round beads (1–6 mm) in potting soil that squirt liquid when popped are **controlled-release fertilizer pellets** (e.g., Osmocote)—not spider eggs.

How to Tell

• Uniform spheres, varying sizes.
• Only in soil from that bag.
• Hard shell, liquid center (nutrient solution).
• No webbing, no movement, no insects present.

Why They're There

Manufacturers add them to feed plants over 3–6 months. They also add perlite/vermiculite for aeration. Both are beneficial.

Rule of Thumb

If mystery soil particles could be fertilizer or drainage aids, they belong there. If not, investigate.

Relax—your soil is enhanced, not infested.
