Will be returning to Galu Beach in 3 weeks and am hoping that someone can provide me with an effective anti sand fly solution. No matter what I use I always get bitten by the blighters, usually in the second week for some reason. I have an allergic reaction to them so end up with large festering blisters that last for weeks and have even been hospitalised on one occassion. I've tried deet sprays, garlic etc.
Any suggestions will be very gratefully received. I've put up with them for the last 5 years, but enough is enough
