Will the hard winter impact on this season’s midge population?
Yesterday’s Times Newspaper reported on the possible impact of the hard winter on this season’s midge population; an interview with Dr Alison Blackwell of Advanced Pest Solutions Ltd. Midges overwinter as larvae, just a few centimetres below the soil surface and are susceptible to ground frosts. However, we’ll have to wait until the Spring to find out if there has been any effect.

EcoGuard Extreme Product Feedback
We are currently collecting feedback on the Saltidin-based insect repellents available at the Midge Forecast Shop. EcoGuard Xtreme is proving to be popular, with comments including:
“Ecoguard Extreme insect repellent - it was excellent. Wild camping in Scotland in late July and not one midge bite (though engulfed in midge swarms)”
and….
“Great product - I’ve been hill walking in Scotland for years and this was an excellent solution to the “midge problem”
EcoGuard Xtreme vs 50% DEET
Saltidin-based EcoGuard Xtreme has been designed to be an effective biting insect repellent, which is gentle on the skin and without the downsides of some other repellents such as being harmful to plastics etc. It is non-toxic, long-lasting, not sticky and is suitable for use on children over the age of two.
The product contains 20% Saltidin (also known as Icaridin) and in laboratory trials with mosquitoes has proved to be at least as effective as 50% DEET, if not better. In trials carried out in Edinburgh with laboratory-reared Aedes aegypti mosquitoes, cages of 30 unfed insects were offered two “attractant” targets to land on; one treated with either EcoGuard Xtreme repellent formulation or 50% DEET, and the other left blank as a control. Mosquito landing behaviour was recorded every 30 seconds for 10 minutes, at 2 hour intervals up until 6 hours (using a different batch of mosquitoes for each observation period).
Whilst the 2 repellents performed similarly for the first 4 hours of investigation, by 6 hours the EcoGuard Xtreme formulation statistically out-per
formed 50% DEET.
EcoGuard Xtreme and will provide good, long-lasting protection faced with the greatest of biting insect attacks. It can be purchased online at the Midge Forecast Shop.
EcoGuard Midge Repellent Performs Well
In it’s first full summer of use, Saltidin-containing EcoGuard Midge Repellent is performing well and even has its own slot on STV each Thursday night. The repellent has beeen formulated to provide safe, effective protection against midges, mosquitoes and othe biting insects. It is gentle on the skin and without the downsides of some other repellents such as being harmful to plastics etc. This makes it an effective alternative to
DEET-based insect repellents.
EcoGuard Midge Repellent has been scientifically developed, with rigorous assessment against Scottish biting midges throughout.
Initially, encouraging laboratory studies of EcoGuard with biting midges demonstrated that the product was as effective as DEET. Following these investigations, field trials were carried out with ‘volunteers’ exposing their repellent-treated forearms at regular time periods throughout the evening with the aim of determining both the efficacy and longevity of the product. The trials were carried out in an area of the Scottish Highland know for its huge midge populations, particularly Culicoides impunctatus, the ‘Highland Biting Midge’.
EcoGuard Midge Repllent contains just 10% of the active, Saltidin (also known as Icaridin). Compared against a 10% DEET formulation, the EcoGuard Midge Repellent provided more than 4 hours protection against the Highland biting midge, whereas the performance of the DEET formulation was very variable between individuals and overall, it provided no significant repellency.
EcoGuard Midge Repellent can be purchased online at the Midge Forecast Shop.

EcoGuard Midge Repellent Field Trial - an update
APS is currently busy on the banks of Loch Laggan carrying out field trials of the new EcoGuard Midge Repellent; the active ingredient is Saltidin®, the sponsors of the Scottish Midge Forecast.
Saltidin® is designed to be an effective biting insect repellent, which is gentle on the skin and without the downsides of some other repellents such as being harmful to plastics etc. It is non-toxic, long-lasting, not sticky and is suitable for use on children over the age of two.
Following encouraging laboratory studies of EcoGuard with biting midges, the current field trials involve ‘volunteers’ exposing their repellent-treated forearms at regular time periods throughout the evening with the aim of determining both the efficacy and longevity of the product. Counts are made of the numbers of midges both landing on- and attempting to feed on the volunteer’s arm.
The image below clearly shows the level of protection provided by the product! EcoGuard Midge Repellent can be purchased online at the Midge Forecast Shop.
