How to identify it

Work down these in order — the first one is usually enough on its own.

  • Nest is a single open comb hanging from a stalk, with hexagonal cells clearly visible
  • Slender waist and long legs that hang down during flight
  • Typically a modest colony, often under a hundred

What it gets mistaken for

Most people arrive at a pest name by ruling things out. These are the ones that genuinely look similar, and the detail that separates them.

Where you will find it

  • Under eaves, soffits and porch ceilings
  • Inside door frames, window frames and shutters
  • Playground equipment, grills and mailboxes
  • Sheds and garages, often just inside the door

Signs it is already there

You will nearly always see the evidence before you see the pest itself.

  • A visible open comb nest, usually in a sheltered spot
  • Wasps repeatedly using the same approach path
  • Nests reappearing each spring in the same place

Moderate. Worth dealing with, but not an emergency.

Why it is harder to deal with than it looks

Knocking a nest down without treating it usually means they rebuild nearby, and doing it from a ladder is how people get stung badly. Sheltered sites tend to be reused year after year.

What actually works

Treat at dusk when the colony is on the nest and least active, then remove the nest once activity stops. Early in the season a small founding nest is far easier to deal with. If the nest is high, near a doorway, or anyone is allergic, that is a reasonable job to hand to someone else.

Common questions

How do I tell a paper wasp from a yellowjacket?

Yellowjackets build enclosed nests with no visible cells, are stockier with tucked-up legs in flight, and are far more aggressive.

How do I tell a paper wasp from a mud dauber?

Mud daubers build tubes of mud, are solitary, and are essentially non-aggressive.

Where are paper wasp usually found in a home?s

Under eaves, soffits and porch ceilings Inside door frames, window frames and shutters Playground equipment, grills and mailboxes.

Is a paper wasp dangerous?

They sting to defend the nest and can sting repeatedly. Risk depends heavily on where the nest sits — one over a doorway is a genuine problem. If anyone in the household is allergic to stings, treat it as urgent.
