The most common types of wasps found in the UK are the European and German wasps.
SIGNS OF A WASP PROBLEM
Wasps build a nest from a papery substance in the cavities of trees, attics, walls and other parts of buildings.
WHAT DO WASPS LOOK LIKE
Their bodies consist of black and yellow bands and they have a narrow waist in the middle of the body. The worker wasp is about 10-15mm in length and the queen is usually about 20mm in length. They have two pairs of wings. Only the females will sting and only when frightened or disturbed.
The queen hibernates over the winter and then creates a wasps nest in the spring in which to lay her eggs.
She feeds her young on dead insects until they grow into sterile worker wasps...
