Wasps coming into rooms from lofts are a common problem in the winter. This usually means that there has been a wasp nest, or even multiple nests, for quite a long time, and the wasps in the nest are now dying out. It is not uncommon for wasps to have a nest in a loft, and complete their whole cycle undetected – starting in the spring and finishing in late autumn/early winter.
Why do I have Wasps Coming from the Loft in December?
The reason is, that although a wasp nests only lasts a year and will die out if left alone they produce new queens for the following year. These Queen wasps have mated with Drone Wasps (the males) from other nests in the Summer and leave the nest in late autumn/early winter to hibernate. Each nest can produce hundreds, and in large nests up to a thousand, Queen wasps for the following year. These Queen wasps leave the old nest and disperse over a wide area. They hibernate, but can cause problems because artificial light and warmth in a house can confuse them and draw them into living areas.
Treatment for Wasps Coming from the Loft in December
PEST UK can apply an insecticide ‘fog’ to the loft area as well as a residual insecticide spray to areas inside rooms (usually walls & ceilings) where wasps are being seen. This type of treatment will reduce the problem but does take time to work as the wasps’ metabolism is very slow so the uptake of insecticide can take some time (2-3 weeks). All the insecticides used by PEST UK are virtually harmless to all mammals.
Price for Treatment of Wasps Coming from the Loft in December
Price for a fogging/residual spray treatment is generally £65.00 + VAT for up to 3 bed house.
