these have been appearing in our office last few weeks and in particular in my room, blinkin huge beasts, soon as we get rid of one or two, more appear, we don't know where from and why their still alive at this time of year. Coming to conclusion something is dead somewhere and there sneaking in.
Friday we flattended several and monday morning there were at least five more attacking us, ended up taking my tennis racket zapper in to work and zapped one first thing today, didn't hit it dead centre, need to practice my Andy Murray shots more , it was up on it's feet dusting it's self down after a few mins, it wasn't up for flying though, I scooped it with the zapper and put it through window, didn't have heart to zap it again.
Let's hope thats the last of them and can get on with some work.
