Only issue for me is slight inconvenience encountered on Thursday. Whilst lying near naked in my garden, I was was surreptitiously approached by a blackish, silent fly about 5mm wide and 15mm long. It settled on my hand and by the time I brushed it off it had drawn blood. A little later (possibly) the same one landed on my leg, where I ended it's existence my means of a sharp slap.
Neither bite was painful at the time and it was only 24 hours later that itchy bumps appeared which seemed to respond slightly to a bit of 'Anthisan' cream.
So, yesterday morning I was bothered twice more by a similar fly. This time I sprayed myself all over with Jungle Formula and had no further trouble, (With the flies at least. See below.) other than the sites of the latter two bites turning into itchy bumps within the last couple of hours.
Research appears to put these objectionable little bastards somewhere into the 'Cleg', or Horsefly group, though I'm certain they aren't the big bastards which are famed for their painful bite.
It seems there are more that 4100 species of 'Tabanidae' or 'horse fly'.
A much bigger inconvenience is the wrath of Mrs Mull, since the overspray from the Jungle Formula left little discoloured spots all over her beloved containerfuls of assorted flowers. The instructions warn against use near fabric, pets, flames, plastic, varnish etc., etc. but make no mention of outdoor container grown plants!
