Count up what your holiday is going to cost (flights, hotel, food, drinks, rentboys, gifts, tips, loss of earnings if employed, loss of business if self-employed).
Draw that money out of the bank in cash
Go on your local gay dating app
Hire local boys until your holiday money is done
No mosquitoes, no airport hassles, no sitting crammed in an aircraft seat for hours on end, no sweating like a pig the minute you step outside, no pushy mamasans
But more seriously - mosquitoes love me even more than I love myself. I have tried everything - sprays, lotions, plug-in insecticide, plug in zappers, wristbands, ankle bands, the electric shock treatment you mention, anti-histamines, hydrocortisone - and nothing works any better that a cheap bottle of SKETOLENE from (I think) Family Mart?? There are two varieties - I think it's the yellow label one that's the more effective.
