Thank you for responding. I can't believe I have bed bugs but I will check again. I am fairly sure I am picking-up these beasts in the garden and am now spraying myself with Autan anti-mosquito. The bite marks are still on my legs and arms from as long as 10 days ago and leave a hard lump under the skin and dark red circles.
I think the Autan will help so am now not so worried about them and do not require any more help from yourself. Thank you.
