Wasps can be useful insects, helping to control other pests
and cleaning up dead insect carcasses. They can even act be pollinators, but mostlyl 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 are unpleasant to most of us with the ability to sting multiple time, but to some they can prove fatal. 
individuals, they can kill. 
two, types of wasp the common
wasp (Vespula vulgaris) and the German wasp (Vespula germanica),  are most common in the UK  both overwinter as queens, the common wasp usually hibernating in
buildings  roof spaces  garden shefs or or in old burrows  the German wasp typically in hollow trees although both will choose any dry sheltered place 
The young queen emerges in the spring, feeding on nectar and begins to
construct her new nest from wasp paper, a mixture of chewed
wood, plant debris and saliva. Favourite places for nests are bellow ground, hollow
trees,  foof spaces attics , garden sheds any dry sheltered  hollow space 
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,  Four to six weeks later, the first  workers
emerge. They are smaller than the queen and all female 
The workers then take over the  nest construction, enveloping the whole
nest in wasp paper,  They also forage for
food, ventilate the nest by vibrating their wings and feed the
developing wasp larvae.
The queen now spends all her time egg laying, each cell being used multiple 
times to rear larvae. By the end of the summer, a nest may house over 20,000
wasps.
In 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

Insect and wasp 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.
