They can damage the insulation in your attic and interfere with the structure of your walls.
Wasp nest attic winter.
If your wasps have built a nest on the floor of your attic bomb style wasp poisons work very well.
As stated we have had hibernating wasp queens in the attic and we found a nest already abandoned.
Once winter is over any surviving queens come out of hibernation and start on the building blocks of a new nest.
Therefore it is a good idea to knock down any empty abandoned nests over the winter and thoroughly clean the area before the queen wasp reclaims the area come springtime.
During winter when the temperatures drop low only the wasp queen gets through the hibernation process the rest of the colony is wiped out completely.
Although wasps will never return to a previously used nest several species of wasp will build their new nest on top of the old one.
So if you intend to go up into your attic or do some renovations in the wall be aware that this hazard is much more prevalent in winter and take measures to protect yourself.
If a person is willing to try to remove a nest a wasp and hornet insecticide should be sprayed directly into the nest opening at night.
Holding the nozzle against the opening will prevent any.
In winter wasps are using your walls and your attic crawl spaces to hide from the cold.
If the nest is a hanging nest make sure you purchase a spray with a projectile shot so that you can completely cover the nest with it.
Wasp nests in the loft or attic another common place to see wasp nests and sometimes an occasional hibernating queen or two is in the loft or attic.

What happens to wasps in winter.
Once the warmer temperatures return those queen wasps will be desperate to get outdoors and start making nests all over your property.
It can take 10 20 days for a wasp nest to die off when treated at this time of year compared with a few hours in july or august.
I am quite protective and never harm the queens.
Spray the nest according to the directions on your spray.
Wasp nests do take longer to die off after treatment in the autumn and winter mainly due to the lower metabolism of the wasps making the absorption of insecticide slower.
All wasps do their part to help the queen wasp survive to lay eggs.
The structure of a wasp nest is able to withstand the meteorological conditions outside but this doesn t mean the wasps will use it again a new wasp is made when the winter is over.
As fall turns to winter you see fewer and fewer wasps in your backyard.
Knock down vacant nests during the winter.
