Wasps
What do they look like?
All the wasps found in the United Kingdom, with the exception
of the hornet, are very similar with black and yellow bands on
their body and two pairs of wings.
Where do they live?
In Spring, the queen leaves her hibernating quarters to seek
nesting sites. These could be holes in the ground, hollow trees,
sheds, loft spaces etc. The queen starts to build her nest with a
papery material that she makes by chewing wood mixed with saliva;
this is known as wasp paper. She will raise the first few workers
who will then enlarge the nest and care for the immature wasps to
follow. The nest construction starts in Spring and will reach its
maximum size in September, when up to 10,000 workers may be
present. An old nest is not used in subsequent
years.
What do they eat?
Wasps usually eat insects, which are mainly garden or
household pests. They also feed on dustbin waste and animal
carcasses.
Pest status
A wasp, unlike a bee, can sting many times. Although the wasp
sting is not normally serious, it can be very painful, and in
certain cases can cause a severe reaction.
Control
Is it necessary?
Nests located in areas away from human contact can be left
untreated. It should be remembered that wasps have a beneficial
aspect as they kill many garden insect pests.
D.I.Y. treatments
If you do decide to treat the nest yourself, suitable products
can be purchased from hardware shops and garden centres. You must
first locate the entrance to the nest. Following the flight pattern
of returning wasps may help. Treatment should be carried out very
early or late in the day when activity is at a minimum. Apply the
insecticide to the entrance of the nest, or directly on to the nest
if it is visible.
Consider the risks carefully before attempting a treatment
yourself. Wasps are very aggressive when their nest is threatened,
and multiple stings may result if your protective clothing is
inadequate.
