Sue,
There are so many products on the market it's mind boggling.
The mosquitos don't bother me much, or at least I should say I don't react to their bite, which is where the problem arises. Last year my sister-in-law reacted very badly to the bites which then became infected. The doctor in Arillas prescribed anti-histamines and said that the allergy would decrease each year...a great excuse to return!
I don't have any favourite repellent, but usually take something containing Deet. This year for a change I have bought a couple herbal sprays and roll-ons for my family and the Avon aftersun with repellent in it. I've also bought Mosi-Bands from Morrisons, they are stretchy bands for wrist or ankles (not too sure about that unless under trousers!) containing 30% Deet/3.5% Citronella and last for 14 days if worn for 7hrs at a time. They have been recommended by friends, who say they have also seen them fastened to baby buggys. I'm going to fasten them to my grandsons buggy as even although the instructions say they are safe for children over 6 mths I would never dream of putting Deet on a young child.
Happy mozzie and bite free holidays to everyone.
