Thanks to Mark and Hendrik I now know that the "bugs are bad this year"
So an extra pack of repellant is packed and clothing can be sprayed if needed. Insect repellants being used are
PreVent, which uses pyrethrins
Autan which uses Icardin (Picardin),
also packed is a BPL headnet. I will report back on the effectiveness of all 3.
Weather the picture gives the current long term predictions, with Green indicating rather certain, Yellow somewhat uncertain (whetever that means) and Red Uncertain. Time will tell on the accuracy of the forecast.
