Midges at Loch Lomond: when they're bad, when they're not, and how to deal with them
Loch Lomond catches people out because it is close to Glasgow and easy to visit. That does not make it soft on midges. You have water, trees, damp ground, campsites and sheltered banks. For day-trippers with no midge experience, a still summer evening at Loch Lomond can be a quick education.

When are midges worst in Loch Lomond?
The main Loch Lomond midge season usually runs from late May through September. June, July and August are the months to take seriously. September can still be bad if the weather stays mild and damp.
Dawn and dusk are the worst times. That matters for camping, evening picnics, paddleboard stops, fishing and anyone trying to sit outside near the water.
Terrain and microclimate note
Campsites on the east bank can be particularly annoying in still conditions because you have trees, water and sheltered air close together.
A decent breeze across the loch can make a huge difference, while a sheltered bay or wooded path can be rough only minutes away. Day-trippers get bitten too.

| Month / period | Often better | Often worse | Terrain note |
|---|---|---|---|
| Late May | Late morning and early afternoon in open shore stretches | Still evenings near wooded or damp ground | Sheltered bays often feel worse than exposed roadside viewpoints. |
| June | Breezier daytime windows | Dusk, east-bank campsites and sheltered lochside stops | Tree cover and calmer shoreline air are the main planning risks. |
| July | Open daytime periods with moving air | Humid evenings by the water | Low sheltered ground near the shore can hold midge pressure surprisingly well. |
| August to September | Fresher daytime windows after windy weather | Settled evenings after damp days | Late-summer nuisance usually lingers in the calmer pockets. |
Best overall windows
Early spring, later autumn, breezy summer days, open shorelines and the middle of the day are usually easier.
Worst overall windows
Still summer evenings beside trees and water, especially campsites, east-bank stops, bays and wooded shoreline.
Calmer experience tip
If you only have a few hours, avoid planning your main stop for a still evening beside trees and water.
Camping note
Camping Loch Lomond midges can be bad around dusk. Bring Smidge, cover skin and consider a head net if you are staying near the bank.
What to bring
For Loch Lomond, do not rely on one trick. Repellent helps, but clothing, timing and wind exposure matter too.
Start with Smidge That Midge. It is the straightforward dedicated option for most visitors and a sensible first buy for Scottish midges.
Avon Skin So Soft Dry Oil Spray is the reputation pick. Some people swear by it, but it is not a dedicated repellent and reliability varies. Fine if you already use it; less convincing as your only protection in still, damp conditions.
Pack a midge head net if you are camping, photographing at dusk, fishing, or walking in still conditions. A head net looks ridiculous until it saves your walk.
A lightweight waterproof jacket handles showers and doubles as skin cover when the midges start working your arms and neck.
If you are choosing between repellents, read which midge repellent works best before buying.
