Problem wasp nest?

Wasps are active as pests in the UK from April to September, with their numbers peaking towards the end of August.

Wasps build their nests inside our homes and businesses. Lofts, sheds, and brick air vents are all suitable locations if left undisturbed. Wasps can be aggressive and can attack if threatened which can be dangerous for those with allergies, small children and pets. Controlling wasps can be dangerous as they will defend their young and nest; although to treat wasps the wasp nest itself does not have to be removed.


At the start of spring, in line with the arrival of warmer weather queen wasps emerge from their inactive winter state looking for a suitable location to build their new nests. The queens never use a nest from a previous year!

As soon as a suitable site has been chosen (loft space, air vent, garage, garden shed etc.) the queen will then look for materials to build her nest. Wooden substances are then collected, chewed, mixed with saliva and wax to create the nest – Wasp numbers remain relatively low.


Wasp nest locations can now be easily located due to a continuous flow of wasps entering and exiting the nest. Wasp numbers usually peak towards the end of the summer / beginning of autumn.


The onset of the colder weather reduces food supplies. With the workers numbers decreasing and new queens looking for a place to overwinter wasps’ nests are vacated towards the end of autumn. Wasp numbers fall dramatically from the beginning to the end of autumn.


Is generally recognised as the safest time to remove and dispose of empty nests. Most nests have been abandoned only very large wasp nests with a good food supply will be active.

Lone queen wasps may be seen finding shelter in the home, on the back of curtains etc. as they look for a place to survive the winter.


Wasps can be confused with bees. Although they are not protected and can be treated, bee numbers are in decline. As such the SCH Better Places team will only destroy a bee’s nest if it poses a substantial health and safety risk. Furthermore, in the case of honey bees we will first look to contact a qualified bee keeper to see if they can come and collect the bees. More information can be found via the: British Beekeepers Association

Only then as a last resort (if removal is not possible and the positioning of a nest is dangerous) will we look to remove the nest.
