As temperatures drop in our area, homeowners often notice a sudden disappearance of bees and wasps that were active all summer. This leads to a common question: Where did they go and are they really gone? The answer depends on the species and whether the insect lives socially in a colony or alone.
Understanding winter behavior helps homeowners know when a nest is harmless, when activity is normal, and when professional help may still be needed.
Social vs. Solitary Insects
Bees and wasps fall into two main categories:
Social insects live in colonies with a queen and workers. These include:
Solitary insects do not form colonies and live alone. These include:
How each group survives winter is very different.
How Bees Survive the Winter
Honey Bees
Honey bees are the exception to most winter rules. The colony does not die off. Instead, bees remain inside the hive all winter, clustering tightly around the queen. They vibrate their wing muscles to generate heat and rotate positions to keep the cluster alive. This is why honey bee hives should never be exterminated and require professional bee removal or relocation.
Bumble Bees
Bumble bee colonies die off in late fall. Only newly mated queens survive. These queens overwinter alone in sheltered locations such as:
• Leaf litter
• Soil
• Cracks and crevices
In spring, each queen starts a brand-new colony.
Solitary Bees
Solitary bees overwinter in different life stages depending on the species:
• Carpenter bees often overwinter as adults inside wood cavities or old nesting holes
• Mason bees typically overwinter as larvae inside sealed nest chambers
These bees emerge in spring and are important early pollinators.
How Wasps Survive the Winter
Social Wasps (Yellowjackets, Paper Wasps, Hornets)
Most social wasp colonies die off after the first hard freezes. Only newly mated queens survive. These queens leave the nest and overwinter alone in protected areas such as:
• Under tree bark
• Inside wall voids
• In attics or sheds
• Beneath logs or debris
The old nest is abandoned and will not be reused.
Solitary Wasps
Solitary wasps usually overwinter as juveniles in:
• Underground burrows
• Hollow plant stems
• Existing cavities
They emerge in warm weather.
Are Bees and Wasps Active in Winter?
Usually no, but there are exceptions. On warmer winter days, you may occasionally see:
• A lone wasp queen emerging indoors
• A carpenter bee moving within wood
• Honey bees briefly flying near a hive entrance
If insects are appearing inside your home during winter, this often indicates overwintering queens sheltering in wall voids or attics, and an inspection is recommended.
Should You Remove Nests in Winter?
Winter is actually the safest time to remove abandoned wasp or hornet nests because:
• The colony is no longer active
• There is no defensive behavior
• There is minimal sting risk
However, nests suspected to belong to honey bees should never be removed without proper identification. Honey bees require humane relocation by a professional beekeeper.

Final Thoughts
Bees and wasps don’t simply disappear in winter, they adapt.
