My wife is a major sufferer from these little buggers and has tried most of the '
home style' remedies.
Baby Oil, Dettol etc worked OK, but left her greasy all day and dramatically increased sun effect. She reckons it only worked because when they landed on her, they got stuck in the oil.
Before one trip to NT, she took Vitamin B1 for a couple of months and continued for a further couple of months, but no noticeable impact. The following year she got some Vitamin B patches, which are supposed to continually leach the vitamin into the body. Again no impact. I have no doubt vitamin B helps some people - clearly no all.
We now have two remedies that seem to help:
The first is continued exposure. After a number of years of exposure - 6 months per year for past 5 years in Northern Australia, mostly NT) has raised her immunity. She still gets bitten, but only comes up in welts when they swarm and she is a bit lax with remedy 2.
The second remedy is Bushman's 40%. We buy it wholesale by the case. Have only used about 8 or 9 cans this winter, probably due to the impact of remedy 1.
In trying to find a solution for her, I did a lot of research, including reading a few scientific papers.
Midges DO NOT PEE on you. The females bite. Like mosquitoes, it is the female that bites and needs blood. It is the saliva she injects that causes the sting and 'allergic' reaction in many people.
DEET is the best repellent. Within reason, the higher the concentration, the longer the protection. But once the DEET concentration passes 30 to 40%, there is no real gain. We still have a couple of tubes of the old 80% DEET cream, but since reading this, we have not used them. DEET concentrations of 20% (like in Aeroguard Tropical) work, but just not as long.
Strangely, Bushman's 40% does not work well on Flies.
When Midges are swarming, you need to cover up very well and spray very well, including under the edges of clothing. The Midges are so competitive for a feed, it seems that any small area without good clothes cover or spray will be bitten. We fish up small mangrove creeks and have proven this many times.
The is no scientific evidence (that I could find) that DEET is harmful when applied to the skn, but there is anecdotal evidence. Only one country has regulated DEET. In Canada, it is illegal to supply personal insect repellents with a DEET concentration above 30%. Their Health Dept web site at the time said it was a precaution. They also advised not using it at all on babies. I think they figured that since there is evidence that going much above 30% does nothing anyway, they might as well be cautious.
I posted this link in a follow up above. Have repeated it here for completeness.
NT Health Dept re Bloodthirsty Midges
As for remedies after the bite. Kathryn uses some Sandfly Salve she got in Broom. Also another one based on Honey and other stuff - not sure of the details. If she has nothing else, she rubs some deodorant on (probably the alcohol does something). All give some relief, but not total. Sometimes a few glasses of wine (administered internally) can also help.

Interesting link off the NT Health Dept site I posted a link to above. A calendar of Midge biting activity.
Wife and I experienced swarms of Midges up the mangrove creeks we like to fish in the past few days. Guess what - these days are coded RED for highest Midge biting activity. I think they know what they are talking about.
They have used a tide chart to indicate the activity - so for us, two birds with one stone. I've now Bookmarked the site for easy reference.
