When we were at the house in September we noticed that a peculiar flying insect had made its home under our roof tiles, just outside the bedroom patio doors. Description is about 30-40mm in length, body divided into two parts, top part about the size of a one pound coin, brown in colour and had a furry/woolly appearance, bottom part about the size of a ten pence piece, yellow in colour, again furry/woolly appearance, from rear of yellow section what looked like a black stinger!!. Questions 1. What is it? 2.Is it dangerous? 3.If so, how do we get rid of? 4.If we can't is there any company etc. who can? Help, don't like sleeping with doors shut
