Wasp Control - Protecting your family or premises from wasp invasions


Wasps can be regarded as generally useful insects, helping to control other pests
and cleaning up dead insect carcasses. They can even act as pollinators, but in
general they are regarded as nuisance pests and a threat to health. Many people
have a genuine phobia against them, in some cases, with good reason.
Wasp stings may be unpleasant to most of us, but to some they can prove fatal. The
ability of these social insects to inflict multiple stings means that for certain
individuals, they can kill. Insects are no respecters of rank, the first recorded instance
of a fatal wasp sting was the death of King Menes of Egypt in about 3000 BC.
Although eleven species of true wasp are found in Europe only two, the common
wasp (Vespula vulgaris) and the German wasp (Vespula germanica), are important
as pest species and increasingly examples of the genus Dolichovespula are being
encountered. All overwinter as queens, the common wasp usually hibernating in
buildings or underground, the German wasp typically in tree cavities and
Dolichovespula is normally found well away from buildings.
The young queen emerges in the spring, feeding on nectar and sap and begins to
construct her new nest from wasp paper, a mixture she concocts from chewed
wood, plant debris and saliva. Favourite places for nests are in the ground, hollow
trees, eaves, attics or garden sheds.
Her first batch of eggs is produced within a few days and the larvae develop within
the nest. The mature larvae construct silken cocoons in which they pupate, still
within the cells of the nest. Four to six weeks later, the first generation of workers
emerge. They are smaller than the queen and all female – male wasps emerge
later in the season.
The workers then take over the ongoing nest construction, enveloping the whole
nest in wasp paper, which could by now extend to eight tiers. They also forage for
food, ventilate the nest (by vibrating their wings) and nurture and feed the
developing wasp larvae.
The queen now spends all her time egg laying, each cell being used numerous
times to rear larvae. By the end of the summer, a nest may house over 20,000
With the onset of autumn, new males emerge to fertilise new queens who go on
to search for hibernation sites. During the winter months the old queen and
workers die and the nest will not be reused.

Wasp Stings

The best treatment for non-allergic people is to wash the site of the sting with soap
and water and apply an anti histamine preparation.
Insect venoms are complex mixtures and they can produce allergic reactions of
two types: respiratory obstruction or a condition known as anaphylactic shock
syndrome. This causes vascular collapse – breathing becomes shallow, the pulse
is almost undetectable, there is profuse sweating and the victim quickly loses
consciousness. Death from wasp stings is rapid, when compared to death from
snake venom; 66% of susceptible victims die within one hour of being stung.


Wasp Life Cycle

  • Queen initiates nest
  • First workers emerge
  • Colony expansion phase
  • Peak worker populations workers become nuisance scavengers
  • New reproductives produced.
  • Colony demise, queen/male mating.

Wasp Control

Despite a high mortality rate, the need to control wasps is more and more obvious,
especially as the number of infestations appears to be increasing. Requests for
control come from two sectors, domestic and commercial and of course, the most
pressing time is in the summer months when nests are at their largest.
Historically, there have been nine principal ways to apply this control:

• Killing hibernating or spring queens.
• Nest destruction.
• Insecticidal baiting.
• Trapping.
• Electric fly killers.
• Contact insecticides.
• Preventative measures.
• Biological control
• Integrated wasp control.
