Midges in Scotland - will they spoil your vacation?

Will midges in Scotland affect your experience of the Scottish Highlands? Nobody ever died from a midge bite. But, yes, they can be a bit of a nuisance.

Midges In Scotland

When it comes to midges in Scotland, let's not beat about the bush. Especially as, if you beat about bushes in the Highlands in the summer, you're liable to disturb clouds of midges. But are these little beasties that much of a problem? Will they spoil your trip?

I've travelled around Scotland for, oh, years and years, and my answer is: possibly a little - but it all depends where you go. If you travel in the Lowlands, and a breeze blows, then midges in Scotland won't be any problem at all.

A quick pronunciation hint: the Scots pronounce the insect as 'mi-jee', emphasising the first syllable. Sometimes midges are called gnats, though the US English 'no-see-ums' is much more colourful and also accurate. Make no mistake, when the conditions are right, these wee beasties can be a bit of an irritation.

Mosquitoes and/or midges?

Sometimes, people confuse the names mosquitoes and midges, especially if Scottish is not their first language. Mosquitoes are much much bigger than midges. Yes, from time to time it seems you do get some mosquitoes in Scotland - that's an Amazon link if they concern you. In any case, they may become more prevalent as global warming increases its impact on Scotland’s environment.

At the moment, mosquitoes are less of an issue - and you certainly won’t encounter any malaria-carrying species.  I think you’ll be much more preoccupied trying to keep yourself midge-free of a Highland evening…and come to think of it, I haven’t seen a single mosquito all summer up here by the Moray Firth anyway.

Buy Some Protection!

But - especially if you heading to the Highlands - you are going to need buy some protection. We find Smidge (Amazon link for anxious US readers there! UK readers see below) plus our trusty Tilley hats very effective - and for really midgie days - an anti-insect head net is recommended!


You could also, I suppose, make your own hat using midge mesh (no, really) though it is more often used for doors and windows. Tests have proved that only a mesh with a minimum of 600 holes per square inch (30x20) will stop a determined midge. Note these figures are for imperial or US measurement midges. Metric midges will be different.

Midges - a Highland problem?

Firstly, some biology. Species of midge that have a taste for us belong to the genus Culicoides. This is a world-wide genus, and the tropical species are even worse. (Don't ask.) There are more than 30 Culicoides species of midges in Scotland. The biting species vary with habitat. The species C. impunctatus is the one you usually encounter in the Highlands.

 

(Pictured here) Midges landing on my hat in quite big numbers, near Shieldaig, Wester Ross. Still evening in high summer so the conditions were just right.

You meet this species of midge in the Highlands because it lays its eggs in wet soil. So anywhere with a good growth of plant species such as sphagnum moss, various rushes or damp-loving grasses will be a potential midge breeding ground. That type of habitat includes much of the high-rainfall Highlands with their acid boggy ground.

Only half the Scottish midge population bites!

Now the good news. Only half the Highland midge population actually bites. The other half is male and feeds on flowers. (Everybody say 'ahwww'.) Basically, the female reaches the adult state with enough reserves to lay one batch of eggs. After that, if she comes over all broody again (and she will) then she needs a blood meal. She needs the protein in the blood to develop the yolk in her eggs.

And that's quite enough detail. Except to say that only about 10% of the females actually get a drink in their little lives.

I can't say I'm sorry about that. That means that 90% of Highland female midges in Scotland just hover around muttering 'Don't know about you, but I could murder a forearm...'

These are the names of the mountains in the background, by the way, not the women in the foreground. And we’ve just got high enough to catch the breeze and avoid Scottish midges.

How to avoid being a Scottish midge meal

There is a wealth of advice available on how to avoid being bitten by midges in Scotland, much of it distilled lovingly down and appearing on this page (which has all you need to know). Midges like to fly, and hence bite, near the ground and seldom attack more than 10ft (3m) above it. So, you could learn to stilt walk. (See? I told you we'd be practical.)

Keep midges off with light-coloured clothing?

Midges are attracted to dark clothing, so wear light colours and cover up. I like to think that some kind of Ku Klux Klan outfit, plus the stilts, might make you practically invulnerable, though a little conspicuous if travelling in a group. (Hmm. I don't know, maybe that observation is in bad taste….)

SUMMER EVENING - VALLEY OF THE RIVER DEE - MIDGE WEATHER

SUMMER EVENING - VALLEY OF THE RIVER DEE - MIDGE WEATHER

(Pictured here) Midges in Scotland love still, warm evenings after rain - as here in the valley of the River Dee, near Banchory, Aberdeenshire. The June evening when I took this picture, I was being eaten alive by the wee beasties. But you'd never know from the photo, would you?

Hold your breath and midges might miss you!

On the subject of what to wear; because midges have very shallow biting jaws, attacks are confined to bare skin. They don't bite through cloth: not even those really cheap t-shirts you got from Walmart.

They home in on their prey by detecting the higher than normal levels of the carbon dioxide that we exhale, although it's unlikely you'll be able to hold your breath for the entire length of your Scottish visit unless your travel agent has really messed with the schedule.

Studies have also shown that midges that feed on humans aren't really that fussy. They are equally happy to feed from cattle, deer, sheep, dogs, cats, rabbits or mice.

You could choose one of these as a decoy species and let it accompany you on your Highland travels. I'd go for something portable, though if you choose a mouse, remember that, to something that size, being bitten by a midge would be, for us, similar to being attacked by, say, a small but homicidal sparrow.

Midges are also especially active in low light and in still conditions. Highland hoteliers rely on this to keep guests in the bar when they might otherwise be taking a romantic walk to watch the sunset. Midges, therefore, are an important element in the Highland economy.

To help solve the biting insect problem, we Scots have installed giant midge-swatters all over the Highlands, only afterwards finding out - d’oh - that these kill bats that eat midges.

(Pictured here.) A giant midge-swatter installation as seen in many parts of Scotland. A failure, as they kill the bats that feed on midges. Still, they have two advantages: they produce clean electricity but, even more important for the Scots, they really annoy Donald Trump.

Take to the water where it's breezy!

Wait, here’s another idea. It’s expanded on our cruise Loch Lomond page but it’s really quite simple. Take to the water - go cruising. Here’s a view looking north-east up Loch Shiel taken from the deck of the Loch Shiel cruise operator’s fine boat Sileas (an ex-Admiralty launch, actually). Not a midge bothered us on that lovely autumn afternoon out on the loch.

Come to think of it, the fact that it was early October may have helped a little, though I had been eaten alive while photographing the Glenfinnan Viaduct just a few days earlier, on an equally sunny day.


Control that midge

No effective blanket spray exists for getting rid of midge on the breeding grounds. You would have to spray most of the Highlands, creating ecological havoc. Ditto biological controls. Dragonflies, amphibians, fish and bats do their best to eat as many as possible. So just remember that if you are a hotelier contemplating one of these midge-zapper devices all you are doing is reducing the food for the local bats.

As for repellents applied to the skin, there is a choice of sprays and creams, some using natural products. At the moment Smidge That Midge Insect Repellent is getting great reviews - see the adverts below. Avon Skin So Soft is also popular. I like my midgehood though - I wear it over my much loved Tilley hat (as vaguely seen in a pic above.)

These also help in keeping away clegs (horse-flies). To be honest, if the midges in Scotland are bad, then clegs are worse! We had a bad experience of Scottish clegs in Knoydart. Oh, and on the road to Stronachlachar in the Trossachs.



Scottish clegs (horseflies)

I think clegs are similar to the US 'blue-tail fly', but perhaps someone can clarify that for me. Don't get me started on these sly and treacherous insects. Clegs - or horseflies - are much bigger than midges, for a start.

The worst thing is the way they silently land on you and the damage is done before you are aware of them. And how do they know that you can't see the backs of your own arms or legs? Clegs are active on warm days in the Scottish countryside - but usually not in anything like the numbers of midges. Reviews of the Smidge spray also say it is effective against clegs... ( hmm, must buy some for Johanna!)

So, basically, midges are part of the Highland experience. They won't totally wreck your holiday and should be no more than a minor nuisance for which remedies are available. Really serious outbreaks may require a midge-hood.  And if you spend a day above, say, 2000ft / 700m - or at lower levels if the wind blows - you won't even encounter them.

So, now you know all about the Scottish midge. An irritation. A real nuisance sometimes. But not really a health risk.

But if you intend to roam about Scotland's countryside, you should be aware of ticks in Scotland. They are potentially a much bigger issue. Seriously, take a look on that link. (But you'll still visit, won't you?)

Finally - and this paragraph has been written quite some time our thoughts on midges was first published - I have to confess that a recent incident involving midges has made me think I have been a little too easy-going about these wee beasties. You can read about it here on a short blog piece somewhat dramatically called:

The Attack of the Killer Midges. It is seldom I actually inhale midges but this was exceptional. Moral: never forget your midge hood in high summer in the Highland moorlands.
