An old nest is also a fire risk. If the nests are near down lights or ceiling lights where the hot element is in the roof/wall cavity, it may catch fire. Wasps mix wood and plant material with their saliva to create a ‘papery’ substance which can be highly flammable, especially when it is old and dry.
If you have any further questions then please do call us.
Wasps can be fatal if the nest is aggravated.
Cause a fire risk -we have been to jobs where wasps have caught fire within downlighters (spot lights fitted in the ceiling/loft)
