Getting dive-bombed at every backyard dinner? You're not alone.
Late summer is peak sting season in Southern California. Wasp and yellowjacket colonies have grown all summer — and now that food is getting scarce, they turn bold and defensive around anything sweet or protein-rich.
Here's what's actually happening:
→ Colonies are at their largest and most aggressive right now
→ They're drawn to trash cans, pet bowls, sweet drinks, and ripe fruit
→ A nest the size of a golf ball today is a real problem by September
Knock a nest down with a store-bought spray and you can end up in stinging range fast — especially with ground-nesting yellowjackets. If it's near a door, eave, or play area, let a pro handle it.
Save this for your next backyard BBQ.
