Remedy Sought

Hi Everyone everywhere
Since February we have been bitten, eaten alive, scratched ourselves until we have bled, kept awake most nights, tried all sorts of products - both preventative and itch resistent claims from bugg off, stop itch, bushmans-red and green, areoguard, rid, the blue stuff from aldies, tee tree oil, mossie coils - both green and brown, sandlewood sticks, swallowed antihistamines, wraped our legs and arms in wet towels... calamine lotion, bethadie cream... deet products, we cover up-as can be seen I am wearing my ugg boots in 30degs!
February we had the march flies and mozzies, we then moved onto mozzies-huge black and white ones and now we have the very tiny black things that look like ash on our bodies but leave a pin prick that itches and when u squash these they distintergarte into nothing.
We are at our wits end - does anyone have a solution??? it seems that the only solution maybe to return to the colder climates-we are reluctant to do this..... perhaps this is the trade off....
From all of us at beautiful Dundee Beach, where we are sweltering in the sun and gazing at the beautiful green flat sea that is riddled with box sting jellyfish and a local crocodile!!!!
O! for that cold one to ease the itch....
