I found this on a recent house survey. In the attic tucked away in the corner by the eaves. A wasps nest as big as five footballs!
To be this size it will have been there for years. Being January and cold there was no sign of activity. When the weather warms up there is likely to be.
The buyer is not happy, and the home seller even less so. A nest of this size needs carefully removing by a pest control contractor. The outside eaves areas need checking in detail for any gaps which should be sealed to prevent a recurrence.
