Fortunately I wasn't strolling around with my pants down so thankfully for them it's not required.
Just a follow up to the vinegar solution, I'm surprised how good it works. I was bitten about 5 or 6 times on my upper arm. I applied the vinegar and within an hour or two there's no sign I was bitten at all, as well as no itchiness or heat irritation.
Well done; I'm surprised and pleased for you that the vinegar remedy works; it is fascinating that something so readily available can work so well, and it is something I will bear in mind for myself. Re heat - scalding hot water and cold (ice packs), I've tried both, and both give relief.
Cheers
