Summer Nuisance Midges

As we start to look forward to the warmer weather, one of the negative aspects might be playing on our minds. Biting insects come out in their thousands during the warmer weather, such as annoying mosquitos and midges.

Midges are the bane of anyone’s life who works outdoors or looks after farm animals. Incredibly, there are over 4,000 species of biting midge!

The pesky biting midges grow through a larval stage and then onto a non-feeding pupal stage of between 2-3 days. They then transform into a winged, flying adult that will live anywhere between 2 and 7 weeks.

Similar to the mosquito, midges love dawn and dusk but can remain active throughout the day, even in rainy and windy conditions. A slightly damp warm day is heaven to a midge, so beware of swarms on days like these and protect yourself and your animals from bites.

They are less active in the colder, winter months but can be around for a large portion of the year, appearing in early spring and hanging around until late autumn.

What does a midge find so attractive about biting a human? Rather scarily, they can detect the carbon dioxide in our breath from a distance of 200 metres! Anyone engaging in outdoor activities or out for a nice walk will be a perfect target for bites if they don’t cover up. For some reason, they are also attracted to dark clothing.
