Quick tip for the crawling nasties - Dettox spray, on earwigs, ants, rain beetles, etc!! Kinder, because it's quick - and it disinfects the area at the same time!
Dreadful!!!! I once stepped into an ants nest without realising, and it was only when I felt itching on my legs that I saw what I'd done. Amazingly, I batted them off without getting bitten once, but I still shudder at the memory.
