I am aware that ticks can carry Lymes disease but, has any info been put out in the public domain as to which areas around britain have these infected blood suckers.?
I always carry Antibiotics 'just in case'
Nonimouse is right that tick prevalence is linked to deer, and as roe deer can be found almost throughout the UK, ticks are pretty ubiquitous. Of course,not all are infected with the organism that causes Lyme.
There was one trial on a bunch of Swedish conscripts that found garlic (taken orally) reduced the number of tick bites - I think by about a quarter, if I recall correctly. So better than nothing, but nowhere near as effective as chemical repellents applied to the skin/clothing.
I'm not aware of any evidence that vitamin B6 can reduce tick bites, and B6 in overdosage most definitely can give you a nasty peripheral neuropathy. The strength of 'over the counter' B6 tablets was reduced because people were getting toxicity from taking excessive doses.
