When the midges are swarming like a biblical plague I think it's fair to say that nothing yet invented is going to reduce the madness to bearable levels, short of giving up and going indoors. Repel five in ten and you'll still have a hundred up each nostril and thousands in your hair. On just such a midsummer evening on Skye - hot, windless and midge infested - we tried to gain some respite with the Thermacell MR150. After about half an hour of hopping around wearing headnets it still hadn't thinned out the hordes so you'd notice. Even holding the device up at head level seemed to make no difference - but then how could it? So far, so inconclusive. Lisäksi pralletriinin ominaisuuksiin kuuluu, että se hajoaa nopeasti ilmakehässä (puoliintumisaika 38 minuuttia).

On several other camping evenings, where midges were also present in low numbers, the Thermacell did seem to make some sort of difference too; but again it's very hard to say how much. Not once have I been bitten by a mosquito while using the Thermacell - I have however received hundreds of midge bites in the line of duty. It's clearly not a silver bullet.The Thermacell MR450 has a more durable body and a quieter ignition than the MR300. Here’s a look at how these Thermacell portable repellents work. My experience has been that if used exactly as recommended - i.e. allow about 10-15 mins burn time for it to warm up, keep it completely flat and use it when there is little wind - it is pretty effective in creating a safe space within a limited sheltered area - enough for a tent entrance or for a couple of people sitting cooking" says Colin Wells.

But while mosquitos are very unpleasant, and in some parts of the world keeping them away is literally a matter of life or death, any UK user is going to know full well that, when it comes to sheer annoyance and persistence, not all small biting insects are equal. The midge, particularly the voracious Scottish variety, is infamous for laughing at repellent and for swarming in thousands. Our synthetic allethrin formula is inspired by repellent extracts found in plants. Independently tested and EPA reviewed for safety & effectiveness. People and pet friendly. The Thermacell MR300 and MR450 are portable mosquito repellents available in a few different models and exteriors. Here’s a look at what you get in the box from the Thermacell MR300 and MR450. hours of mosquito repellent and fuel included. Unscented repellent mats last up to 4 hours each and change color when time to replace. No mess and easy to refill.I've only used this unit for a few months, but I know a man who's had one for seven years, so I thought he'd be worth asking: Apparently the compounds have low toxicity for humans and birds, but you certainly don't want to get too close. And keep cats away, as allethrins are toxic to them. Thermacell-laite käyttää tehoaineena pralletriini-nimistä hyönteistorjunta-ainetta. Thermacell-hyttystorjuntamaton pralletriinipitoisuus on pieni, 11,61 % eli 0,19 grammaa. I'd say that for moderately midgey conditions it's probably better than nothing, but that when midge-mageddon strikes the Thermacell is as effective as anything else - which is to say, not very.
