Bite's

My wife is the same. Avon "Oh So Soft" (the blue one) works well and apparently it is used by the armed forces. The other thing the wife has been doing is taking vitamin B tablets each day. She gets less bites and they are less aggressive.
A mosquito net suit works but hasn't got much street cred.

Thanks peegeenine

When you say the "Blue One" is that the colour of the bottle or the make?

Jungle Formula protects me - and they love the taste of me.  You can also get Jungle formula plug  ins - available from Boots usually.  Jungle Formula after bite is good as is Anthisan from the chemist to soothe!   Avon's Skin So Soft (you can get it online) seems to work well too although I haven't yet tested it against Highland midgies! 

It's the blue bottle. Pippah45 got the name correct.

Anti-histamine tablets from the chemist can help and the already mentioned anthisan cream. I've got a supply of Avon Skin So Soft "Original" bought on Amazon, not sure it really works but worth trying maybe. Midges are a bit selective with their victims, I built up an immunity when living in Scotland but they're still a **!!@@ nuisance!

If you are experimenting with different ideas, try garlic in your diet, or one garlic capsule a day, Might work.

I've eaten marmite every morning of my life pretty much and the blighters still bite me. Tried products containing DEET which appears to work, one called Off seemed the best but only purchased that in Canada.

I speak as one who spent a number of Summers in and out of hospital with blood poisoning due to insect bites! One bite, and area would swell up, but around joints it was as if someone had tie wrapped me! Excruciatingly painful.

I now get prepared from March onwards, taking one a day Loratideine tablets, that don't make you drowsy, they don't like Vitamin B, so yes, Marmite and yeasty products help. Use insect repellents if necessary, keep away from known mosquito hotspots. Doesn't stop the blighters biting, but it does help keep the infection and pain under control. I also find ice cubes on sore area can help. There are some really good reports for using the Avon So Soft product, in fact I think Inread somewhere that it is so good the Royal Marines use it!

Yes another one for Avon Skin so Soft, the Rangers up in Scotland also use it

Cant help with prevention but a great product for after bite is Benadryl skin allergy relief.  Takes the itchiness away pretty quickly.
