Only honeybees die after stinging. Wasps can sting repeatedly.
Frequently asked
Answers to the questions homeowners ask most about wasps.
How do I tell a wasp nest from a bee hive?
Wasp nests are paper-like with visible cells; honeybee colonies build waxy vertical combs.
Will the nest come back next year?
Not the same nest — but the location may attract new queens; treat and remove to prevent re-nesting.
